Bryan Woo wasn’t highly regarded when the Seattle Mariners selected him in the sixth round of the 2021 draft out of Cal Poly. That’s understandable. The low-slot righty had a 6.36 ERA in his three collegiate seasons, including a 6.11 mark in his injury-hampered junior year. After undergoing Tommy John surgery in April 2021, he made his professional debut in ’22.

Now, the 24-year-old is showing that Seattle’s director of pitching strategy, Trent Blank, wasn’t completely out of his mind when he reportedly told members of the Mariners front office prior to the draft that “this guy would be one-one for me.” While it’s unlikely that Woo is going to be as good or better than all of the 173 players drafted ahead of him, his numbers have nonetheless been impressive. Since making his big league debut in July 2023, he has a 3.60 ERA and a 3.96 FIP over 137 1/3 innings across his 28 starts with the Mariners. In 10 outings this year, he is 4-1 with a 2.54 ERA and a 3.25 FIP. It’s worth noting that this success hasn’t exactly come out of nowhere. Including four rehab outings this year, Woo logged a 2.97 ERA and 162 strikeouts over 115 innings as a minor leaguer.

Woo brought up his backstory when I asked him how he’s developed as pitcher.

“Going through the draft-and-scouting process, I feel like a lot of it was based on my potential,” Woo told me when the Mariners played in Cleveland last month. “I didn’t have great results at the time. It was based off of, ‘He could be this. It looks like he’s developing into that.’ For me, it was about believing that I could get there, that I could continue to get better. That’s kind of the story. I wasn’t too well-known. If you look at in on paper, it was never, ‘This guy is really good.’ The numbers never really showed that I was.”

Not surprisingly, Woo also brought up the fact that he’d been injured when he was drafted, and how that made for a lot of uncertainty. As he put it, “I didn’t quite know what was going to happen. It could have been a little higher. I could have gone a lot lower. I really wasn’t sure.”

He did know that his repertoire needed both refinement and enhancement. The Oakland native had a mid-90s four-seam fastball when healthy but nothing else to write home about. His slider, which he described as having been “OK,” was a pitch he’d throw here and there. He also had a changeup, but that mostly sat in his back pocket.

Developing a second heater has been especially impactful for him. He added a two-seamer to his arsenal last year while toeing the rubber for the Arkansas Travelers.

“Last year, before I got called up, our pitching coordinator came down to Double-A, where I was at,” Woo said. “He sat in on one of my bullpens and said, ‘Just try it.’ I was having a lot of high pitch count games — I wasn’t getting many quick outs — and he said that it could be a tool to use to get some quicker outs, some weaker contact. A lot of my game was strikeouts and fly balls. There weren’t many efficient outs, I guess you could say. So, we tried the two and it has progressed from there.”

So far this season, Woo has thrown 51.4% four-seamers and 27.2% two-seamers, as well as 7.2% changeups, 7.1% sweepers, and 7.0% sliders. The last of that mix, according to the righty, acts more like a gyro when he throws it low, and more like a cutter when he throws it toward the top of the zone. His circle changeup is a pitch he described as having “a little less vertical and a little bit more horizontal, as well as little bit slower, than my sinker.” Asked which of his off-speed pitches he sees as his main secondary offering going forward, he said that he’s satisfied with the progress of all three and wouldn’t take one over the other.

As for his two fastballs, the 6-foot-2 Woo wasn’t inclined to pick between them either. Instead of choosing favorites, he described why he’s had success with his heaters despite their relatively unimpressive metrics.

“Neither one plays super high metrically; the vertical and horizontal movement aren’t anything crazy,” Woo said. “I think it’s just my slot, kind of how the ball comes out, that makes them a little bit different.”

The slot is indeed different. As Pitcher List’s Jack Foley explained last summer, “At 4’11” off the ground, Woo has a release height a full foot below the average.”

Woo told me that he was more over the top in high school, only to have his arm “kind of lower on its own throughout college, post-surgery, and pro ball.” He claimed to have never purposefully dropped it down, but rather has just continued to throw in a way that feels most comfortable. Not so comfortable are opposing batters. They have just a .220 xBA and a 2.7% barrel rate against the low-slot righty this season. When healthy — he missed the first month with elbow inflammation and later was on the shelf for three weeks with a hamstring strain — Woo is hard to square up.

Welcome back to Top of the Order, where every Tuesday and Friday I’ll be starting your baseball day with some news, notes, and thoughts about the game we love.

With just seven days to go until the July 30 trade deadline, let’s round up some news and developments from the last few days and discuss how these nuggets might affect what happens over the next week. Here’s what’s new:

The Mariners Blow Their AL West Lead

Remember when the Mariners had a 10-game lead in the AL West at the end of play on June 18? Well, they surely do, and not fondly, now that it’s gone. They salvaged Sunday’s series finale against the Astros to avoid the sweep and enter the new week in a virtual tie for first, but it took just 24 games for them to blow that double-digit lead. That’s the quickest that any MLB team has ever lost a 10-game lead in its division standings.

Anyone who’s watched even a small handful of Mariners games can tell you that the offense has been the big issue for the team. Potentially making matters worse: Julio Rodríguez was removed from Sunday’s game after twisting his right ankle while leaping for a ball against the wall in center field. X-rays came back negative, and after undergoing an MRI on Monday, he’s listed as day-to-day with a mild ankle sprain. Then, in Monday’s 3-1 loss to the Angels, shortstop J.P. Crawford fractured his right pinky finger when he was hit by a pitch in the first inning. It was announced after the game that Crawford will be placed on the IL; there is no timetable for his return. Meanwhile, the Mariners placed first baseman Ty France on waivers. Though he can continue to play while he’s on waivers, he was not in the lineup Monday, and after the game he was seen cleaning out his locker, an indication that even if he clears waivers, he is not returning to Seattle.

Also not helping this offense is its home ballpark: T-Mobile Park is the most pitcher-friendly park in the league. But even by park-adjusted stats, Seattle’s offense has been quite poor; only the Pirates have a worse wRC+ among the teams with a winning percentage of at least .500.

The Mariners are still clearly on the buying side of teams entering the deadline, but their playoff hopes largely rest on winning the division outright; entering Monday, our Depth Charts projects them to have a 49.8% chance to make the playoffs and 39.6% odds to win the AL West. Back on June 25, about a weak after Seattle’s high-water mark in the standings, I wrote about the team’s anemic offense and some of the players who could help improve the lineup if the Mariners were to acquire them in a trade. All of those hitters remain with their same clubs, and Seattle’s evaporated division lead should provide the team with even more incentive to add as many impact bats as possible. The Mariners should target players whose skill sets are more “T-Mobile Park proof,” but it’s hard to imagine this offense could be worse off with any of the possible upgrades that it may acquire over the next week.

James Paxton’s DFA Sets up Musical Chairs for the Dodgers

It was a little surprising to see James Paxton get designated for assignment as the Dodgers’ corresponding move to add top pitching prospect River Ryan to their roster ahead of his MLB debut on Monday, but the fact of the matter is that Paxton wasn’t going to last much longer in Los Angeles anyhow. While he’s tied with Tyler Glasnow for the team lead in starts (18), his outings were a mixed bag at best; he averaged under five innings per start and walked 12.3% of batters faced, by far a career worst.

The Paxton-for-Ryan swap is just the first of many rotation moves coming up for the Dodgers, who will welcome Glasnow back from the injured list on Wednesday and Kershaw on Thursday. The Dodgers will have to cut a reliever to make room for Kershaw, setting up a rotation with Glasnow, Kershaw, Gavin Stone, Landon Knack, and either Ryan or rookie lefty Justin Wrobleski. Alex Vesia is the only reliever who can be optioned, and he’s not going anywhere, so the team will have a tough DFA decision afoot. My guess is that Yohan Ramírez and Anthony Banda are the most vulnerable.

But that’s just the first round of musical chairs, with at least one of Walker Buehler (hip discomfort) and Bobby Miller (ineffective and banished to Triple-A) needing a spot at some point, which could leave Knack exposed to getting optioned despite his effectiveness when called upon. There’s also the trade deadline, at which point the Dodgers may well add yet another starter to the mix.

Banged-up Braves Bolstering Bats?

Max Fried and Ozzie Albies recently became the latest in a long line of Braves players to land on the injured list.

Dan Szymborski detailed the specifics of the injuries yesterday, but the upshot is this: Whit Merrifield (who, ironically, hurt his thumb taking grounders before his first game with the Braves and is currently day-to-day) and Nacho Alvarez Jr. probably aren’t enough to paper over the loss of Albies for two months, Atlanta’s strong rotation was already spread thin before Fried got hurt because Spencer Strider is out for the year and Chris Sale and Reynaldo López are often pitching on extra rest as Atlanta monitors their innings.

Fried’s injury is reportedly a best-case scenario, so maybe the Braves feel like they can get by for a month or so with guys like Dylan Dodd, Bryce Elder, AJ Smith-Shawver, and Allan Winans, but as Dan noted, losing Albies creates a not-insignificant hit to their Playoff Odds. It certainly doesn’t help matters that Matt Olson and Orlando Arcia have struggled mightily for most of the year.

Positional flexibility fits best for the Braves, who will have Michael Harris II (and almost certainly Albies) back for the playoffs. Better versions of Merrifield (guys who can slide between the infield and outfield) include Jazz Chisholm Jr., Luis Rengifo, and Amed Rosario.

The Tigers Hold the Keys

The Tigers are on a nice little run of late, but they’re a game under .500, which makes selling at the deadline all but a guarantee. The question is this, though: To what extent will they sell? Jack Flaherty is the best rental starter on the market by far, and fellow pending free agents Mark Canha and Gio Urshela should follow him out the door to make way for younger bats auditioning for roles next year. Andrew Chafin and Shelby Miller, who have club options for 2025, could be on the move as well if the Tigers don’t plan on having them around next season anyhow and want to avoid paying their buyouts. All those players, Flaherty especially, could return something of value, but none would alter the franchise even 10% as much as would a Tarik Skubal trade.

The Dodgers and Orioles are reportedly talking to the Tigers about Skubal, and while it would be shocking to see Detroit trade the best lefty starter in baseball when he has over two years left before he’s scheduled to reach free agency, it’s still worth considering the possibility. Skubal comes with as much club control as the White Sox’ Garrett Crochet, who is far likelier to be traded, and it stands to reason that Skubal would fetch a significantly better return than Crochet.

There’s not a right answer for what the Tigers should do with Skubal. Really, the only wrong answer would be getting an unworthy return package for him because they traded him for the sake of trading him. For this reason, the Tigers are most likely going to let suitors come to them with their best offers for Skubal, and they’ll trade him only if one of them is too good to turn down.

Editor’s Note, 9:37 a.m. ET: This story has been updated to include the latest information about the Mariners’ injuries and Ty France.

Welcome to another edition of Five Things I Liked (Or Didn’t Like) this week. This is a strange week for the column. The All-Star break cut into the number of games available to watch; mathematically speaking, fewer games means fewer chances for weird things to happen. I took a weekend trip and didn’t watch any MLB games on Friday or Saturday. I’m also hard at work on the upcoming trade value series, which comes out between the All-Star game and the deadline every year – check back Monday for that annual exercise’s kickoff. In any case, that means this is a hodgepodge list: some stuff from this week, sure, but also plays and series that got left out last week, and some low-level baseball to boot. Thanks, as always, to ESPN’s Zach Lowe for the format idea. And two quick programming notes: I won’t be doing my regular Monday chat or Five Things next week; instead, I’ll be doing a jumbo-sized chat Friday morning.

1. The New Derby Format
The modern swing-happy Home Run Derby has been a great success, at least as far as I’m concerned. It’s more fun to see sluggers launch as many home runs as they possibly can than it is to see them agonize over every single swing. The format wasn’t perfect, though. I’m not trying to be a grump about it – is it even possible to be a grump about the Home Run Derby? – but there was one downside to the timed-round format: not enough drama.

Today the Killers list turns the corner — or rather turns to the teams receiving less-than-acceptable production in the outfield corners. While still focusing on teams that meet the loose definition of contenders (Playoff Odds of at least 9.5%), and that have gotten about 0.6 WAR or less out of a position thus far — which prorates to 1.0 WAR over a full season — I have also incorporated our Depth Charts’ rest-of-season WAR projections into the equation for an additional perspective. Sometimes that may suggest that the team will clear the bar by a significant margin, but even so, I’ve included them here because the team’s performance at that spot is worth a look.

As noted previously, some of these situations are more dire than others, particularly when taken in the context of the rest of their roster. I’ve batched the two corners together into one supersized roundup because three of the seven teams below the WAR cutoff for left field also make the list for right field, and because there’s plenty of crossover in play with regards to personnel. The capsules are listed in order of their left field rankings first, while noting those three crossover teams with an asterisk. As always, I don’t expect every team here to go out and track down upgrades before the July 30 deadline, but these are teams to keep an eye on. All statistics are through July 14.

Let’s start with a riddle: Team A and Team B have both played 98 games this season. Due to the vagaries of extra innings and unplayed bottoms of ninths, Team A’s pitchers have thrown four more innings than Team B’s pitchers. However, Team B’s pitchers have faced 259 more batters than Team A. How is this possible?

OK, yeah, so this was actually a pretty easy riddle. The answer is that Team B’s pitchers stink, while Team A’s pitchers are very good. Team A gets a higher percentage of batters out, which means that it faces fewer batters per inning. Let’s put some names and numbers to our hypothetical, shall we? Allow me to introduce you to the Mariners and the White Sox.

The Mariners have better pitchers and a better defense behind them. Consequently, the White Sox have allowed a whopping 130 more runs. But take a look at the last row of that table. The White Sox have thrown the most pitches in baseball, while the Mariners have thrown the second fewest. Having good pitching and good defense has allowed them to throw 1,477 fewer pitches than the South Siders. The average team throws 146 pitches per game, so we’re talking about 10 entire games’ worth of pitches. Ten games! That is a huge number, and these teams still have 64 games left to go.

Today, we turn our attention to the second base Killers. While still focusing on teams that meet the loose definition of contenders (a .500 record or Playoff Odds of at least 9.5%), and that have gotten about 0.6 WAR or less out of a position thus far — which prorates to 1.0 WAR over a full season — I have also incorporated our Depth Charts’ rest-of-season WAR projections into the equation for an additional perspective. Sometimes that may suggest that the team will clear the bar by a significant margin; as you can see by the table below, four of the six teams listed here project to receive more than a win from their current cast of second base options. Even so, I’ve included them here because the team’s performance at that spot is worth a look, and the incumbent may no longer appear to be the best option.

Particularly in light of those projections, I don’t expect every team to go out and track down an upgrade before the July 30 deadline, though I’ll note that some of the players cited within for their poor performance are themselves change-of-scenery candidates; one team’s problem may be another team’s solution, albeit not necessarily an ideal one. Either way, I’m less concerned with those solutions – many of which have more moving parts involved than a single trade — than I am with the problems. Unless otherwise indicated, all statistics are through Sunday.

Josh Rojas has turned himself into a plus defender. My colleague Ben Clemens chronicled that advancement last month, citing the Mariners infielder’s improved ability to go to his left as a primary reason for his markedly-better metrics. Exactly what type of adjustments have allowed the 30-year-old third baseman to turn the proverbial corner with his glove? I happened to be in Cleveland when Seattle began a road series against the Guardians on the day Ben’s article ran, so was able to get the answer right from the horse’s mouth.

“It was a matter of adjusting what works best for me reacting to balls left and right,” Rojas told me. “It has to do with my preset. Not getting down too early, not getting down too late. Picking up contact points. Another thing that helps is knowing how the ball usually comes off guys’ bats when certain pitchers are throwing. There is constant communication between me, the pitching coaches, and Bone [infield coach Perry Hill] on what the plan is for the series.”

The preset is what I was most interested in, so I asked the erstwhile Arizona Diamondback — Rojas became a Mariner at last July’s trade deadline — if he could elaborate. Read the rest of this entry »

In a race for a playoff spot, every edge matters. Yet all too often, for reasons that extend beyond a player’s statistics, managers and general managers fail to make the moves that could improve their teams, allowing mediocre production to fester at the risk of smothering a club’s postseason hopes. In Baseball Prospectus’ 2007 book, It Ain’t Over ‘Til It’s Over, I compiled a historical All-Star squad of ignominy, identifying players at each position whose performances had dragged their teams down in tight races: the Replacement-Level Killers. I’ve revisited the concept numerous times at multiple outlets and have adapted it at FanGraphs in an expanded format since 2018.

When it comes to defining replacement level play, we needn’t hew too closely to exactitude. Any team that’s gotten less than 0.6 WAR from a position to this point — prorating to 1.0 over a full season — is considered fair game. Sometimes, acceptable or even above-average defense (which may depend upon which metric one uses) coupled with total ineptitude on offense is enough to flag a team. Sometimes a club may be well ahead of replacement level but has lost a key contributor to injury; sometimes the reverse is true, but the team hasn’t yet climbed above that first-cut threshold. As with Supreme Court Justice Potter Stewart’s definition of hardcore pornography, I know replacement level when I see it.

For this series, I’ll go around the diamond, pointing out the most egregious examples of potential Killers at each position among contenders, which I’ll define as teams that are above .500 or have Playoff Odds of at least 9.5%. That definition covers 20 teams, down from 22 last year. I’ll include the rest-of-season projections from our Depth Charts, and while I may mention potential trade targets, I’m less focused on these teams’ solutions than I am the problems, because hey, human nature.

Below is an analysis of the prospects in the farm system of the Seattle Mariners. Scouting reports were compiled with information provided by industry sources as well as my own observations. This is the fourth year we’re delineating between two anticipated relief roles, the abbreviations for which you’ll see in the “position” column below: MIRP for multi-inning relief pitchers, and SIRP for single-inning relief pitchers. The ETAs listed generally correspond to the year a player has to be added to the 40-man roster to avoid being made eligible for the Rule 5 draft. Manual adjustments are made where they seem appropriate, but we use that as a rule of thumb.

A quick overview of what FV (Future Value) means can be found here. A much deeper overview can be found here.

All of the ranked prospects below also appear on The Board, a resource the site offers featuring sortable scouting information for every organization. It has more details (and updated TrackMan data from various sources) than this article and integrates every team’s list so readers can compare prospects across farm systems. It can be found here.

Julio Rodríguez is having a down year with the bat. Three months into the season, the 23-year-old Seattle Mariners center fielder is slashing just .257/.308/.343 with seven home runs and a 92 wRC+, numbers that are well below the .279/.338/.495 with a 135 wRC+ and 60 home runs he put up over his first two big league campaigns. There are a pair of silver linings, though. One is that Rodríguez was markedly better in the second half of the 2023 season (a .942 OPS) than he’d been in the first half (.721). The other is Seattle’s record. Even with the superstar performing at less than his usual standards, the Mariners are 45-36 and sitting atop the AL West standings. If Rodríguez were to repeat last season’s second-half resurgence — something you might not want to bet against — that surely would go a long way toward helping propel Seattle’s postseason push.

In the 104th installment of our Talks Hitting series, Rodríguez discussed his early development as a hitter, how he balances staying the course with a need for change, and the perspective he takes when looking at his stat sheet.

———

David Laurila: How did you first learn to hit?

Julio Rodríguez: “Little League. I just picked up a bat with my dad and started swinging it.”

Laurila: Do you consider yourself a natural hitter?

Rodríguez: “Kind of, yeah. I could say that. In Little League, I had my coach and all that, but my dad was a big part of it too. There was a point where he was kind of my coach before I went to this academy in Santo Domingo, in the Dominican Republic. He, as well as some other coaches, helped me out.”

Laurila: What is your father’s baseball background?

Rodríguez: “He just played amateur — he didn’t do professional — but he loved the game. That’s why I started playing.”

Laurila: What about hitting instruction when you went to the academy? Read the rest of this entry »
