Pitchers learn and develop different pitches, and they do so at varying stages of their lives. It might be a curveball in high school, a cutter in college, or a changeup in A-ball. Sometimes the addition or refinement is a natural progression — graduating from Pitching 101 to advanced course work — and often it’s a matter of necessity. In order to get hitters out as the quality of competition improves, a pitcher needs to optimize his repertoire.

In this installment of the series, we’ll hear from three pitchers — Tyler Anderson, Steven Brault, and Mike Leake — on how they learned and developed their change-of-pace pitches.

———

Tyler Anderson, Colorado Rockies

“In high school, I tried to learn how to pitch by watching other people. And I was doing all kinds of stuff. I was dropping down, throwing from all arm angles, throwing sliders. Then I got to college. At the University of Oregon, they preached fastball-changeup. Not only that, in the fall you weren’t allowed to throw breaking pitches; you had to go fastball-changeup only. Then, just before the season started, you could start mixing in curveballs and sliders.

“Before that, I’d thrown a palm ball. Honestly. I would hold it in my palm and throw a palm ball. It was slower. My dad knew about it from back in the day — it’s an old-school pitch — and mine was actually pretty good. It didn’t have a lot of spin, and as you know, limited spin creates drop. Mine would drop a lot, but it was too hard to control. Read the rest of this entry »

After a strong 2017 campaign for Tampa and Baltimore led some observers to declare, perhaps prematurely, that the former No. 1 pick had finally figured out how to sustainably deliver on his sky-high potential, Tim Beckham’s 2018 performance was sufficiently awful (a 79 wRC+ over 402 plate appearances) that the Baltimore front office declined to tender him a contract and left him to sign a $1.75 million deal with the Mariners in early January. Well, for a guy who was probably only intended to hold the middle of the field warm until J.P. Crawford gets the call up to Seattle at some point later this summer, Beckham has had a remarkably good first week in the Queen City:

Usually, I wouldn’t note a first week like this except in passing — Preston Tucker was hitting .435 through his first seven games of 2018, after all — except for two things. First, Beckham was hurt — with a core muscle injury that required surgery — throughout much of 2018, which suggests that perhaps his poor performance over the full season was less a reflection of a regression from 2017’s breakout and more what you’d expect from a player toughing it out through a debilitating injury. Second, Beckham has actually had a pretty good five weeks, dating back to September 1st of 2018. Since that date, his wRC+ of 186 is eighth-best in the game.

Beckham has always had good power to all fields, but until 2017, that power was too often undercut by a tendency to end at-bats early by swinging at the first pitch he saw offered close to the zone. In 2017, he solved the mental hurdle that had pushed him to try to do too much and instead started taking a few pitches early in at-bats until he found the one he wanted. “These days,” he told me back then, “I want to see the ball in the zone where I can drive it, and if it’s not” — here, a pause — “I want to trust that it’s going to be a ball.” The core injury hindered his ability to execute on that mindset in 2018, yes, but since September of last year, he’s been able to put it into practice again. The results have been impressive. Read the rest of this entry »

It’s been a whirlwind few weeks for Yusei Kikuchi. Not only did he see his first action as a major leaguer, a well-documented dream of his since his high school days, but his father passed away after a long battle against cancer. He is staying in the United States in accordance with his father’s wish that he concentrate on baseball. It is quite hard to imagine what the young pitcher must be feeling, and we wish for the best for him and his family in this difficult time.

Kikuchi has made two starts for the Mariners. While some data exists from his days in the NPB, MLB presents a new challenge. We can’t reach any grand conclusions about him as a major leaguer yet, but we can make observations and possibly, some extrapolations. At this moment, here are the basic numbers: 10.2 innings pitched, five hits, three earned runs, two home runs, eight strikeouts, and one walk. Kikuchi currently has a 2.53 ERA and a 4.25 FIP. It’s too early to make any calls, but Seattle has got to be pleased with the return so far.

Our analysis of this limited sample becomes trickier because we only have Statcast data for one of his starts. His Tokyo start – you know, the one where Ichiro announced his retirement mid-game – is not registered there because the Tokyo Dome isn’t equipped with Trackman or PITCHf/x cameras. So, we have his 91-pitch start against the Red Sox on March 29, which is quite a small sample to work with. Kikuchi’s tendencies could change as he pitches in the majors and adjusts to either his strengths or hitters’ weaknesses (or both). With those the caveats understood, his early efforts still merit examination.

Let’s start with the obvious here: the fastball. Since he was an acclaimed prospect at the Hanamaki Higashi High, Kikuchi has been known in Japan for his fastball velocity. In 2017, he set what was then an NPB record for the fastest pitch recorded by a left-handed pitcher with a 158 kmph (roughly 98 mph), though it should be noted that his average fastball velocity was 148.6 kmph (around 92.3 mph). In 2018, his velocity slipped a bit. According to Delta, an NPB sabermetrics site, it went down to 147.3 kmph (around 91.5 mph) last year. He suffered shoulder tightness that was later diagnosed as decreased functionality of shoulder last year, so that seems to have played a part in the decline in velocity. Of all his pitches, the fastball is the only one that Eric Longenhagen and Kiley McDaniel did not describe as above average in their write up of Kikuchi for in this year’s top 100.

Against the Red Sox, Kikuchi averaged at 93.1 mph. Statcast had him as high as 95.4 mph. It is not Ohtani-esque big velocity, but it is a range that should work in the majors, especially if he can maintain it through starts consistently locate it like this:

By average velocity, he’s comparable to the likes of David Price and Sean Newcomb. Maybe he’ll gain a tick or two as the season goes on or maybe he’ll get worn down. I don’t know. But as far as the velocity goes, Kikuchi can say he belongs in the majors. One thing of note is that his fastball only induced a whiff once out of the 43 times he threw the pitch. Statcast measured the pitch’s average spin rate at 2,173 rpm. According to Travis Sawchik, an average fastball around 93-94 mph measures out to 2,240 to 2,300 rpm. At least for that one start, his fastball was not seen to be a swing-and-miss weapon, as his velocity would indicate. Obviously, Kikuchi has arm strength, but not all 93 mph fastballs are created equally. Luckily for him, he has another tool in his toolbox that drew many more swings-and-misses: his slider.

Kikuchi’s slider features a nasty 10-5 tilt. He used it as a swing-and-miss pitch in Japan, and he’s used it as one in his early going in the majors as well. Against Boston, he generated seven whiffs from 22 sliders used, which is pretty good! Here’s one to Xander Bogaerts that I feel is representative of how he likes to use the pitch.

And here’s one to Sam Travis that had a particularly vicious bite.

Looking at Kikuchi’s slider heatmap from that game, we see a lot of low and inside pitches to the right-handed heavy Sox lineup. Being aware of his pitch tendencies from the NPB, I’d assume he meant to locate them that way as well. It’s hard to draw a conclusion at this moment, but Kikuchi’s slider has been rated above-average, as noted by Eric and Kiley. Future value grades don’t always come to fruition, but I would say that Kikuchi’s slider could forecast well in the majors.

As for the bad, Kikuchi did not necessarily avoid the meat of the zone. Here is his pitch heatmap:

The good here is that Kikuchi located well to the inside edge versus right-handed hitters, and away versus left-handed hitters. However, there’s that big dark and red circle towards the middle-up part of the strike zone that indicates that he was also prone to leaving pitches “up there.” FanGraphs rated his command as a 45-grade, which is just below major league average. As of this moment, Kikuchi has thrown 64% of his pitches for strikes and allowed only one walk in 10.2 innings pitched. Those are good control numbers. Command is a different thing. The Red Sox hitters were much less than forgiving on Kikuchi’s mistake pitches.

Here’s J.D. Martinez going yard on a fastball right down the middle. The catcher had his glove up and in, but the ball missed the spot and Martinez drove it over the center field fence.

Here’s another home run allowed, this time against Xander Bogaerts. The explanation is simple – the catcher appears to have wanted it down and away but the fastball went right down the middle, which is likely to be punished by many major league hitters.

Pitching is extremely hard. You must stand a mark and locate each pitch into a glove size smaller than a pie tin from 60 feet 6 inches away. But it’s also the nature of the business – if you miss even so slightly, major league-caliber hitters can hit it a long way. It is worth noting that every pitcher makes mistakes. It’s the matter of minimizing the amount of them. There will be days when Kikuchi will makes fewer mistakes, and there will probably be days he makes more.

What’s curious for now is that Kikuchi has noticeably bumped up his curveball usage. Here’s the chart of his March 29 start versus his 2018 pitch data with the Seibu Lions, thanks to the NPB sabermetric website Delta.

It’s an interesting bump. He never threw his curve more than 11.1% in a season with the Seibu Lions. He was known for his fastball/slider mix in Japan. The curveball, according to multiple scouting reports, was a third pitch that he would use to give different looks. And it’s not just his start against the Red Sox either. Over at Lookout Landing, Jake Mailhot recorded Kikuchi’s pitch data by hand during the Athletics game in the Tokyo Dome. The chart below indicates that Kikuchi has shown very similar pitch mix for his first two starts as a big leaguer.

One theory on why Kikuchi increased his curveball usage lies in data. Last June, Jim Allen of Kyodo News wrote on how Kikuchi relies on data to make adjustments to things like his release point and extension. I’m not sure how much attention he puts on his pitch metrics, but his curveball does grade out well on Statcast. Take a look at his pitch data from Baseball Savant:

Not only does an effective curveball give hitters another thing to worry about, but the velocity difference can also make his heater stand out more. Here’s a curveball that he threw to the reigning AL MVP Mookie Betts. Betts reacted like he was not expecting this pitch. He held up a for a microsecond and got his bat head out, but made weak contact that ended up being a groundout.

He didn’t generate any whiff with the pitch, but it induced two bits of weak contact for an overall .124 xBA. He also used it to get ahead in counts. Out of 18 curves thrown, nine of them were called strikes. Here’s one of them to Betts.

Kikuchi has had two decent starts and the pitch has worked well, so I don’t anticipate him making drastic changes anytime soon. It will be something to monitor, though. History has shown that many successful pitchers – Tanaka, for instance – have demonstrated the ability to modify their approach to survive in the majors. As time goes on, major league teams will have a book on how to approach Kikuchi. Once they know better what to expect, I don’t know how successful they’ll hit against him, but surviving in the majors involves series of adjustments. If Kikuchi runs into a harder time getting hitters out, I would expect him to take a different approach.

Lastly, it’s worth noting that Kikuchi seemed to struggle when facing the order the third time around. In a very small sample, Kikuchi faced five batters a third time through the order between the A’s and Red Sox games, and allowed two hits, including that aforementioned JD Martinez home run. Again, it is hard to draw conclusions out of five-batter sample, but the concern is not unfounded. The lack of a big fastball could become a problem late in games in instances where he struggles to give hitters different looks. As Bill Petti has written for FanGraphs about how pitchers with a big fastball — who can maintain that velocity late in games — are more likely to pitch deeper.

There will be so much more Kikuchi to watch. Personally, I’ve waited for awhile for him to arrive to the majors, as I’ve written about the lefty a couple of times in the past. Two starts in, Kikuchi gave his team a real chance to win on both occasions. For a starting pitcher, there’s not a lot more you can ask for.

Spring training numbers need to be taken with a grain of salt, but there’s no denying that Ryan McMahon has been a monster in the month of March. In 59 Cactus League at bats, the Colorado Rockies infielder banged out 25 hits while slashing a behemothic .424/.470/.763. His 1.233 OPS led the leaderboards in Arizona and Florida alike.

No, he isn’t about to approach those numbers in games that count — this isn’t Ty Cobb we’re talking about — but the 24-year-old is being counted on to provide value to the Rockies lineup. Three games into the regular season, he’s done just that. McMahon has four hits, including a pair of doubles, plus two walks, in a dozen plate appearances. Lilliputian sample size? Sure, but it’s nonetheless a nice start for the 2013 second-round pick.

His 2018 rookie season was a disappointment. In 202 big-league PAS, he fanned 64 times, and logged a .683 OPS. That came on the heels of spring training numbers which, while not as heady as this year’s, suggested he was ready to rake at the highest level. Instead, he scuffled.

McMahon is self-aware enough not to have forgotten last year. Asked a few weeks ago about his scorching spring, he reminded reporters that it had only been a few dozen at bats — spring training at bats, no less — and that “Baseball is a very humbling game. You never have it all the way figured out.” Read the rest of this entry »

Sure, he’s won seven straight batting titles in Japan, but it’s telling that, in English, “Ichiro Suzuki” roughly translates to “Can’t hit Pedro.”

– The Utah Chronicle, March 30th, 2001

It is late afternoon in Seattle, and it is the beginning of April, and it is quite cold. The Mariners are going to play the Oakland A’s. Today, the baseball starts counting. Across the infield dirt, just behind second base, a few faint letters mark the time: 2001.

More than 45,000 people are here, the most that have ever crowded into this still-new stadium. There’s less team spirit on display than you might expect. Most of the attendees aren’t flaunting jerseys; they’re bundled up, hands tucked into coats. The fading sunlight falls over the stadium from behind the pale, high clouds, and as a few Mariners take the field, running sprints across the outfield grass, a hearty cheer rises up to greet them. The men in white stretch, pulling arms and bouncing in lunges, before trotting back to the dugout. Not much longer, now. Not much longer.

High up on a view level fence, in front of a kid and their dad, you can see a white posterboard, letters painted in amateurish block text: “WELCOME ICHIRO.”

Many of them know only what the numbers can tell them, the list of achievements that made him worth tens of millions. Seven straight batting titles and a lifetime .353 average. Some may have gone down to spring training, gathering in the Arizona heat, and seen it for themselves: 26 hits, catching batting practice fly balls behind his back, throwing runners out at third with seemingly effortless throws from deep right. The speed — the Mariners said they’d clocked his home-to-first time at 3.7 seconds. (The fastest average home-to-first time among major leaguers in 2018 was 3.86.) Read the rest of this entry »

Even if you didn’t wake up at an ungodly early hour to watch Thursday’s Mariners-A’s game at the Tokyo Dome, by now you may have seen the stirring footage of Ichiro Suzuki exiting the game in the eighth inning en route to his official retirement. If not, beware the coming dust storm:

That the 45-year-old Suzuki — who was nudged off the Mariners’ roster and into an unofficial retirement and special assistant role last May 3, at a point when he was hitting .205/.255/.205 through 47 plate appearances — went 0-for-5 with a walk and a strikeout in his two-game cameo matters not a whit as far as his legacy is concerned. His awe-inspiring total of 4,367 career hits (1,278 in Nippon Professional Baseball, 3,089 in Major League Baseball) still stands as the signature accomplishment for a player who has spent more than a quarter-century serving as a wonderful ambassador for the sport on two continents. His stateside resumé, which includes not only his membership in the 3,000 Hit Club (despite not debuting in the majors until he was about half past his 27th birthday) but also his 10 All-Star appearances, 10 Gold Gloves, AL MVP and Rookie of the Year awards, and so on, is ample enough to guarantee him first-ballot election to the Hall of Fame. In the wake of Mariano Rivera’s groundbreaking unanimous election to the Hall in January, it’s even possible that Ichiro could replicate the feat.

The question is when. Hall of Fame election rules require a player to be retired for five seasons before appearing on the BBWAA ballot, which means that had he been content to hang up his spikes last May, he would have been eligible for the 2024 ballot (the date refers to the year of induction, not the year of the ballot’s release, which is typically in late November or early December of the previous year). Barring what would be an unprecedented ruling by the Hall, his two-game cameo resets his eligibility clock, pushing him to the 2025 ballot, a small price to pay for his being able to check off the bucket-list item of retiring on his own terms, in his native country. Not only will he become the first Japanese player to be elected to the Hall, but according to the Baseball-Reference Play Index, he will be the owner of the shortest final season of any elected position player.

Update: Following Seager’s surgery, it appears that he will now miss 10-12 weeks, rather than the six weeks or so estimated at the time this article was written. Please update your misery accordingly.

Last Friday, Kyle Seager dove for a ball that was smacked down the third-base line by the Cubs’ Javy Báez and hurt his hand in the process. Scott Servais removed Seager from the game during a subsequent pitching change, and the Mariners announced Monday that the third baseman would undergo immediate surgery to repair an extensor tendon in his left hand. I am not intimately familiar with extensor tendons as a matter of course, but I understand they’re what allow you to straighten your fingers and thumbs. Since you need to be able to do those things in order to play baseball, Seager will be out six weeks.

Because the Mariners aren’t expected to be very good this year — their 75-87 projection is better only than the Rangers’ in their division — this isn’t the kind of injury that you’d expect to materially affect the way the season plays out for Seattle, but it is kind of a bummer for Seager, who had a pretty bad year last year and could use a bounceback. Here are Seager’s numbers for 2011-2017 and 2018, respectively:

There’s a reasonable argument to be made that some of Seager’s under-performance last year was due to an unusually low BABIP (.251, compared to a career mark of .281), and that .178 ISO isn’t too far off his career mark of .183, but it’s hard to write off the sudden spike in strikeout rate — Seager posted a 14.3% full-season mark as recently as 2015 — especially when it comes, as it does, alongside a three-year slide in contact rate, from 83.4% in that 2015 season to 78.8% last year. Last year, for the first time in his career, Seager had a negative run value  on fastballs (-0.69 per hundred seen). Something, clearly, was a little off. Read the rest of this entry »

We’re just a week away from actual major league baseball games and two weeks from Opening Day, and the free agent market is about spent. Dallas Keuchel and Craig Kimbrel remain free agents for now, the only two available players projected for two or more WAR on our depth charts. Even lowering the bar to a single win only adds two additional names in Carlos Gonzalez and Gio Gonzalez.

Unless your team is willing to sign Keuchel or Kimbrel, any improvements will have to be made via a trade. And since pretty much every team could use an improvement somewhere, it’s the best time of the year for a bit of fantasy matchmaking until we get to post-All Star Week.

Note that these are not trades I predict will happen, only trades I’d like to see happen for one reason or another. Until I’m appointed Emperor-King of Baseball, I have no power to make these trades happen.

1. Corey Kluber to the San Diego Padres for Wil Myers, Josh Naylor, Luis Patino, and $35 million.

One of the reasons the Kluber trade rumors so persistently involved the Padres this winter is because it made so much sense. The idea was that Cleveland had a deep starting rotation and an offense that looked increasingly like that of the Colorado Rockies, with a couple of MVP candidates and abundant quantities of meh elsewhere.

On the Padres side, the team’s lineup looked nearly playoff-viable in a number of configurations with the exception of a hole at third base. The team was awash in pitching prospects but had a drought of 2019 rotation-ready candidates.

These facts have largely stayed unchanged with the obvious exception of San Diego’s hole at third base. The Padres aren’t far away from contending, and while signing Keuchel is cleaner, revisiting Kluber is a bigger gain.

At four years and $28 million guaranteed after the trade’s cash subsidy, Myers actually has some value to the Indians, who have resorted to fairly extreme measures like seriously considering Hanley Ramirez for a starting job. Most contenders aren’t upgraded by a league-average outfielder/DH, but the Indians would be. Cleveland can’t let Kluber get away without taking a top 50ish prospect, and Naylor is a lot more interesting on a team like the Indians, which has a lot of holes on the easy side of the defensive spectrum, than he is on one that wants to be in the Eric Hosmer business for a decade.

Unfortunately, in the end, I expect that Cleveland wasn’t as serious about trading Kluber as they were made out to be and would likely be far more interested in someone who could contribute now, like Chris Paddack. And Paddack makes the trade make a lot less sense for the Padres, given that they have enough holes in the rotation that they ought to want Kluber and Paddack starting right now.

2. Nicholas Castellanos to the Cleveland Indians for Yu Chang, Luis Oviedo, and Bobby Bradley.

The relationship between Castellanos and the Tigers seems to oscillate between the former wanting a trade and both sides wanting to hammer out a contract extension.

Truth is, trading Castellanos always made more sense as the Tigers really aren’t that close to being a competitive team yet, even in the drab AL Central. Castellanos is not a J.D. Martinez-type hitter, and I feel Detroit would be making a mistake if lingering disappointment from a weak return for Martinez were to result in them not getting value for Castellanos.

While one could envision a future Indian infield where Jose Ramirez ends up back at second, and Chang is at third (or second), I think the need for a hitter, even if the first trade proposed here were to happen, is too great. Oviedo is years away and Cleveland’s window of contention can’t wait to see if Bradley turns things around.

3. Dylan Bundy to the New York Mets for Will Toffey and Walker Lockett.

I suspect that if the Mets were willing to sign Dallas Keuchel, he’d already be in Queens. In an offseason during which the Mets lit up the neon WIN NOW sign, they’ve confusingly kept the fifth starter seat open for Jason Vargas for no particular reason.

Rather than wait for Vargas to rediscover the blood magicks that allowed him to put on a Greg Maddux glamour for a few months a couple of years ago, I’d much rather the Mets use their fifth starter role in a more interesting way. Bundy has largely disappointed, but there’s likely at least some upside left that the Orioles have shown little ability to figure out yet.

Toffey would struggle to get at-bats in New York unless the team’s plethora of third-base-capable players came down with bubonic plague, and given that the team isn’t interested in letting Lockett seriously challenge Vargas’ role, better to let him discover how to get lefties out on a team that’s going to lose 100 games.

4. Mychal Givens to the Boston Red Sox for Bryan Mata.

Boston’s bullpen was a solid group in 2018, finishing fifth in FIP and ninth in bullpen WAR. But it’s a group that is now missing Kimbrel and Joe Kelly, two relievers who combined for 2.2 of the team’s 4.9 WAR. The Red Sox haven’t replaced that lost production, and while they talk about how they really think that Ryan Brasier is great, they already had him last year. Now he’ll throw more innings in 2019, but that will largely be balanced by him not actually being a 1.60 ERA pitcher.

The Red Sox have dropped to 22nd in the depth chart rankings for bullpens, and although ZiPS is more optimistic than the ZiPS/Steamer mix, it’s only by enough to get Boston to 18th.

The Orioles are one of the few teams who might possibly be willing to part with bullpen depth at this point in the season and Givens, three years from free agency, gives the Red Sox the extra arm they need. Mata is a fascinating player, but he’s erratic and Boston needs to have a little more urgency in their approach. The O’s have more time to sort through fascinatingly erratic pitchers like Mata and Tanner Scott.

5. Madison Bumgarner to the Milwaukee Brewers for Corey Ray and Mauricio Dubon.

You know that point at a party when the momentum has kinda ended and people have slowly begun filtering to their cars or Ubers, but there’s one heavily inebriated dude who has decided he’s the King of New Years, something he proclaims in cringe-worthy fashion to the dwindling number of attendees?

That’s the Giants.

The party is over in San Francisco, with the roster not improved in any meaningful way from the ones that won 64 and 73 games in each of the last two seasons. The Giants are probably less likely to win 90 games than George R. R. Martin is to finish The Winds of Winter before the end of the final season of Game of Thrones.

You can’t trade Bumgarner expecting the return you would for 2016-level Bumgarner, but you can get value from a team that could use a boost in a very competitive National League.

6. Mike Leake to the Cincinnati Reds for Robert Stephenson.

An innings-eater doesn’t have great value for the Mariners, who are unlikely to be very October-relevant. The Reds seem like they’ll happily volunteer to pick up the money to keep from trading a better prospect; they can’t put all their eggs into the 2019 basket.

With Alex Wood having back issues, a Leake reunion feels like a good match to me, and with Stephenson out of options, he’d get more time to hit his upside in Seattle than he would with a Reds team that really wants to compete this year.

7. Melvin Adon to the Washington Nationals for Yasel Antuna.

Washington keeps trading away highly interesting-yet-erratic relievers midseason in a scramble to find relief pitching. Why not acquire one of those guys for a change and see what happens? Stop being the team that ships out Felipe Vazquezes or Blake Treinens and be the team that finds and keeps them instead.

The Giants have a bit of a bullpen logjam and realistically, a reliever who can’t help them right now isn’t worth a great deal; relief is a high-leverage role and by the time Adon is ready, the Giants will likely be a poor enough team that it won’t matter. They may already be! Antuna gives them a lottery pick for a player who could help the team someday in a more meaningful way.

Below is an analysis of the prospects in the farm system of the Seattle Mariners. Scouting reports are compiled with information provided by industry sources as well as from our own (both Eric Longenhagen’s and Kiley McDaniel’s) observations. For more information on the 20-80 scouting scale by which all of our prospect content is governed you can click here. For further explanation of the merits and drawbacks of Future Value, read this.

All of the numbered prospects here also appear on The Board, a new feature at the site that offers sortable scouting information for every organization. That can be found here.

Other Prospects of Note

Grouped by type and listed in order of preference within each category.

Corner Hitters With Fringy Offensive Profiles
Joe Rizzo, 3B
Dan Vogelbach, DH
Joey Curletta, 1B
Eric Filia, 1B/RF
Keegan McGovern, 1B
Ariel Sandoval, RF

We’ve never been huge on Rizzo despite his obvious feel for contact because his frame has been maxed out since high school and we weren’t sure where sufficient power was going to come from, especially if he were to ever move off of third base. He’s still just 20 and had respectable peripherals at Hi-A last year, so we’ll continue to keep tabs on him despite our skepticism. Vogelbach and Curletta might each see big league time this year. Vogelbach’s approach prioritizes contact over the type of selectivity he’d need to have to get to all his power. His bat control makes this approach viable, but it may not generate offense that clears the bar at 1B/DH. He may be a good buy low target for an NL team trying to get ahead of the universal DH implementation. Like a lot of Dodgers and ex-Dodgers, Curletta’s batted ball profile has shifted and become flyball heavy over the course of several years. He did have 23 dingers last year, though he was a 24-year-old in Double-A and struck out quite a bit. Those two are both younger than Filia, who has raked for his entire college and pro career amid several off-field issues and a trade that fell through due to a medical red flag. He may fall into a late-career Lenny Harris type role if a team has enough defensive flexibility elsewhere on its roster. McGovern was a high-priority senior sign who remade his physique and had a tool uptick. He’s 23 and will need to move quickly. Sandoval has big power and runs well, but the 33% strikeout rate is ominous.

Sleeper Arms
Sam Delaplane, RHP
Deivy Florido, RHP
David McKay, RHP
Brayan Perez, LHP

Delaplane has a 2700 rpm curveball and low-90s sinker, and he hides the ball pretty well and K’d 100 hitters in 60 innings at Low-A last year. Because he’s a cold-weather college arm, it’s a little more acceptable that he performed that way at 23, and we think he’s an interesting sleeper who might get pushed quickly this year. Florido will be 18 all year. He sits 87-89, has modest physical projection, advanced fastball control, and feel for spin. McKay was part of a group of minor league players the Mariners acquired from the Royals for cash early in 2018, presumably for minor league depth reasons. Seattle ‘penned him, and it turns out McKay is actually a decent fastball/slider middle relief prospect. Perez is an 18-year-old pitchability lefty who threw well in the DSL; his stuff is currently a bunch of 45s and 50s and his arm action is good, but the frame limits projection.

Older Relievers
Nick Rumbelow, RHP
Art Warren, RHP
Brandon Brennan, RHP

These are all relief or depth types in the age 25-27 range. Seattle gave up Juan Then to acquire Rumbelow from the Yankees and he barely pitched last year due to a nerve issue in his neck. When healthy, he’s 92-95, and touches 97, with an above-average changeup and slider. Warren pared his repertoire down and is now a fastball/slider middle relief prospect of somewhat advanced age. Brennan was the team’s Rule 5 pickup; his report is available here.

System Overview

This list, of course, looks much different than last year’s iteration, which was arguably the saddest list we’ve ever done, the Charlie Brown Christmas tree of prospect lists. Of course, stocking this system with several of the high-profile names now present cost Seattle 2018’s best reliever, a shortstop with a 70 bat, a Dominican icon, an emerging if perhaps unassuming face of the franchise, and Mike Zunino.

Most of the prospects Seattle acquired in return are relatively close to the majors, supporting the front office’s public assertions that this will be a short-term rebuild. Additionally, the two teenagers in the system most likely to be stars (Rodriguez and Kelenic) are quite advanced for their age, and could be on an accelerated developmental path that enables them to overlap for a while in the big leagues with the other 50 FV prospects in the system, even though they are about four or five years older than Kelenic and Rodriguez on average.

There will be prospect entropy — J.P. Crawford, who doesn’t look so great thus far in the spring, is a great example of this. Not all of these guys will end up as good as we and the Mariners currently project them to be, and this system is still pretty thin beyond the names who were brought on this offseason. The structure of the rebuild indicates intelligent design, but chaos and entropy will play their role. Mitch Haniger (who looks like a star), Domingo Santana (who has the talent to be one), and the charismatic Mallex Smith (who may sneakily already be one) will be fun to watch while the kids grow up.

We still don’t know a lot about this org’s player development. The swollen physiques of the Jack Zduriencik era seem to be a thing of the past as the strength and conditioning program has improved, but this group really hasn’t had much talent to mold, let alone enough to draw results-based conclusions about the player dev approach, and the cement is pretty dry on the 50 FV prospects listed above.

How much better is this system now than at the end of the year? It was last by a good bit in Craig’s end-of-season analysis and, while we consider re-working our math, it has currently moved up into the 14-19 range in all of baseball.
