On the surface, Justus Sheffield’s developmental journey looks pretty smooth. He was a first-round pick back in 2014. He’s been a consensus top 50 or so prospect since the Obama administration — never much higher than that, but only rarely lower (Eric and Kiley had him ranked 60th overall and first in the Mariners system preseason; he’s since dropped to 109th and seventh respectively). His velocity has not materially changed. He’s suffered a few bumps and bruises, but nothing ever sidelined him long. Twenty-three years old now, he’s cracked a big league rotation right on schedule for a high school draftee of his caliber.

Statistically, he’s been consistent as well. With the exception of a very poor early season spell this year, he’s maintained an ERA under 3.40 at every minor league stop. His strikeout numbers have almost always hovered just above a batter per inning, his walk totals around 3.5/9. He typically generates more grounders than flies. Every year, a new level; every year, the same successes.

Yet Sheffield’s path has actually meandered a bit. As a high schooler, the lefty was seen as an athlete who would have no trouble throwing strikes and a guy who could develop three plus pitches. Two years into his career, he effectively pocketed one of them, shelving his curve in favor of a hard slider. He also grew quite a bit soon after the draft. Between the added weight, a new pitch mix, and a difficult delivery to repeat, his control suffered and whispers about a bullpen role grew louder even as he continued missing bats. His velocity, while stable in the aggregate, has periodically fluctuated on either side of the low-90s. We’ve learned that Sheffield’s fastball has a very low spin rate (more on that later).

He also got traded twice. On the one hand, Sheffield has had the opportunity to hone his craft under the tutelage of two of the sport’s finest pitching development staffs. On the other, those same clubs ultimately decided to work with different pitchers. As he’s matured, and as his fastball looks less like a bat-misser and his changeup remains a work in progress, he’s increasingly relied on his slider. The soothing consistency in his production belies a conflict between the quality of that slider and the reality that he must throw something else eventually. How that conflict resolves itself will shape his ultimate role.

The bullpen has long been the logical end point here. As a starter, Sheffield sits in the low-90s, touching 95 or a tick better at his strongest. In relief, he’d throw even harder. Pair increased velocity with a slider that earns a whiff nearly a quarter of the time he throws it, and you’ve got a late-inning reliever. Lefties, even ones with serviceable changeups, usually peak as eight-inning guys out of the pen. But on paper, Sheffield’s cocktail is good enough to close. Read the rest of this entry »

For teams that have been eliminated from playoff contention, September is a time for youngsters and debuts. Giving prospects a few weeks of major league experience is one of the great side effects of expanded rosters during the last month of the season. The Mariners have been auditioning their young talent since June — they’ve rostered 67 different players this season, a major league record — but the group of September call-ups were exciting nonetheless. After the Arkansas Travelers were eliminated from the Texas League playoffs, the Mariners promoted a group of four players from their Double-A affiliate: Donnie Walton, Art Warren, Justin Dunn, and Kyle Lewis.

Dunn and Lewis were the headlining names of this squad. Dunn had been ranked towards the back of a few top-100 prospect lists after his breakout last season. Lewis was a much bigger surprise. A first-round draft pick in 2016 — Jerry Dipoto’s first draft after taking over as Mariners GM in late 2015 — Lewis’s professional career was derailed almost as soon as it started. A nasty collision at home plate practically destroyed his knee after just 30 games in the minors. That injury sapped him of much of his athleticism and mobility for more than a year and he wasn’t fully healthy again until 2018. In that time, he tumbled down prospect lists and soon became an afterthought in an organization desperate for talent on the farm. Read the rest of this entry »

For the first time in a while, the Mariners weren’t playoff-adjacent in 2019. Depending on your point-of-view, over the last decade the Mariners have either been the worst playoff contender or the greatest also-ran in baseball. Rarely a thoroughly dreadful team, the mid to late 2010s Mariners were a fringe playoff threat in most seasons, typically flirting with contender status before staying home to listen to old Morrissey albums. It’s now been 18 years since the last time Seattle played postseason baseball. Team executive VP/GM Jerry Dipoto is banking on the notion that the organization can remedy that state of affairs with a quick retooling, initiated before the team reached the direst of straits.

The Setup

The 2018 Seattle Mariners played baseball quite adequately, winning 89 games, the team’s most since 2003. It wasn’t enough to punch a ticket to October, thanks to the Houston Astros winning 103 games and it taking a 97-win season merely to tie with the second wild card team, the Oakland A’s. The Mariners made it interesting and were able to stay close to the Astros for most of the year. The team’s divisional deficit didn’t permanently stretch to more than five games until late August. They scared Houston for a while, grabbing sole possession of first-place for part of June. Perhaps most impressively, the Mariners did it with bandaids and duct tape; former cornerstone players Félix Hernández and Kyle Seager were no longer stars, and second baseman Robinson Canó missed most of the midseason thanks to an 80-game suspension for a banned substance.

After the season, the Mariners made a rare decision for an 89-win team: they blew it up. The decision to enter a rebuild is a hard one, typically resulting in multiple years of struggle. But one of the advantages of going this route is that the Mariners were better able to control their destiny. Unlike the Orioles or the pre-Luhnow Astros, Seattle wasn’t forced to take a long view by having a system devoid of talent at the major and minor league levels.

For an extremely active executive like Jerry Dipoto, having a lot of options is important. The 2018-2019 Mariners were still able to find someone interested in Canó, and rather than treating a closer as a player you build around *coughRedscough*, they bundled Edwin Diaz with some cash and were able to land Jarred Kelenic and Justin Dunn. In addition to getting two of their top five prospects from the Mets — both ranked 50 or better by THE BOARD — the Mets picked up some spare baubles in Anthony Swarzak and Gerson Bautista. Even Jay Bruce, mostly brought in to make the cash work, has been occasionally useful in recent years. Read the rest of this entry »

A man in black stands in the bullpen. He looks different than the last time we saw him here, almost six months ago now. The strange uniform hangs off him so loosely; his hair is clipped shorter; his beard is longer. It is the early evening, and the sky is loosely clouded, the light and shadow falling in that way that is so familiar now, the way it only does in this specific place, this close to the ocean in the west.

The energy, though, is not familiar for this building: the loud blue everywhere, the excitement of thousands who are experiencing something they can only have once a year, or once every few years, or even once in a lifetime. They are not here for the man in black; he might as well be one of the shadows.

In the corner, though, above the bullpen, the faithful form their block of yellow. They hold up their signs, and the kids wear their little foam crowns. And if it wasn’t for the fact that the words they hold up mirror the ones sewn to the back of his uniform, you might not know that the person they were so excited to see is the same subdued presence now taking the man.

It is the 209th time that Félix Hernández has started a game in this ballpark. Read the rest of this entry »

In Steph Curry’s junior season, his Davidson Wildcats played a non-conference game against Loyola Maryland. Curry led the nation in scoring at the time, and as expected, Davidson rolled that night. But Curry himself didn’t score a point. Loyola’s coach, Jimmy Patsos, instructed his players to double-team Curry up and down the court. So, Curry stood in the corner with two Greyhounds next to him as his teammates played 4-on-3 and won by 30.

After the game, Patsos more or less copped to the farce. Defending his tactics, he asked: “Anybody else ever hold him scoreless? I’m a history major. [Are people] going to remember that we held him scoreless or we lost by 30?”

Whether all that makes Patsos infamous, cynical, or pathetic is up to your interpretation. Regardless, he’s right about one thing: you can generate attention in defeat, even humiliating defeat, so long as you lose in notable fashion.

It’s a lesson the Seattle Mariners reinforced over the weekend. On the surface, Sunday’s matchup between Seattle and Houston looked as lopsided on paper as a major league game can. The Astros are perhaps baseball’s best team; the Mariners may lose 100 games. Cy Young contender Gerrit Cole was on the mound for Houston, opposed by former Cy Young winner but current-6.00-ERA-holder Félix Hernández. The Astros had already defeated Seattle 15 times in 16 tries. Vegas handicappers set one of the highest lines I can ever remember seeing for a major league contest.

This being baseball, anything can happen on any given day, and as it turned out, 35,000 Houstonians saw a pretty spectacular version of “anything:” the most lopsided ballgame in recent memory. Read the rest of this entry »

If you follow baseball from the East Coast, it’s easy to forget about Kyle Seager. Though never quite as famous as his performance would merit, he’s been a star for the better part of the last decade — he and Félix Hernández were the solitary workhorses trying to drag the Mariners out of a playoff drought and back to glory. Seager arrived in the majors at the tail end of Félix’s peak, but they were both always there, annually among the game’s best and never in the playoffs.

That feels like eons ago now. The Mariners have been redefined since then; by Jerry Dipoto’s manic trading, by the delight of watching Daniel Vogelbach hit, by painful injuries and eagles landing. Meanwhile, time has dragged the old generation down. With Félix’s rapid decline as a guidepost, it’s easy to lump Seager in with him as a deprecated model of Mariner.

The numbers tell the story. From 2012 to 2016, Seager posted a wRC+ between 108 and 134 every season and averaged 4.5 WAR per year. He seemed to only be getting better — 2016 was his best season yet, a 5.2 WAR, 134 wRC+ masterpiece when he struck out only 16% of the time and walked at a 10.2% clip. A down 2017 (106 wRC+) was understandable, with a low BABIP and slightly worsening plate discipline dragging down his overall line, but a downward trajectory for a 29-year-old was enough to make observers a little worried.

2018 was worse — his walks plummeted, his strikeouts ballooned to 21.9%, and he posted a lower ISO than he had in dead-ball 2014 on his way to an 83 wRC+. He started 2019 on the injured list after hand surgery, a worrisome injury for any hitter. It was slow going upon his return, and as the Mariners wilted after their strong start, it felt as though Seager’s career was doing the same. Read the rest of this entry »

September call-ups, both high-profile and totally innocuous, have been trickling in over the transaction wire for the last several days. As always, there are some who will have real impact on the playoff race and some who are interesting for the purposes of player evaluation, like your usual spare lefty reliever and catcher (by far the most common types of September additions). Some teams with no new names at all. Below I’ve compiled notes on every player brought up by an American League team since the start of the month, no matter how inconsequential; I’ve slipped some rehabbers and August 31 acquisitions in here, too. It’s a primer for you to get (re)acquainted with players who might impact the playoff race or the seasons to come. (The National League’s complement can be found here.)

Contenders’ Reinforcements

Houston Astros– OF Kyle Tucker, C Garrett Stubbs, RHP Josh James, RHP Jose Urquidy

Kiley and I have Tucker projected as an above-average regular, ranked 15th overall among prospects in baseball. I have no idea what kind of playing time he might get this month. Stubbs (24th in the org) has begun playing a little bit of second base and outfield. A part time, multi-positional role might help keep his tiny frame from breaking down, and enable Houston to get his long-performing bat in the lineup, as well as create flexibility on other parts of the roster.

James was 94-97 in rehab outings before he returned, then reached 99 on Monday. Urquidy projects as a strike-throwing fifth starter.

New York Yankees– OF Clint Frazier, RHP Jonathan Loaisiga, RHP Ryan Dull, RHP Chance Adams, LHP Tyler Lyons, INF Brenny Escanio (prospect)

I think it’s likely Frazier, who many scouts/teams continue to think has everyday ability, gets traded this offseason, both because he’s part of a crowded outfield/DH mix and because he and the org don’t seem to be a great fit. Read the rest of this entry »

A little over a decade ago, the soft-tossing lefty was all over the place. There was Barry Zito, Mark Buehrle, and Ted Lilly. Late-career Tom Glavine, Kenny Rogers, and Jamie Moyer were getting by on guile, too. Even Mark Redman and Chris Capuano were getting outs without much velocity. Looking around today’s game, we have Jason Vargas trying to hang on and CC Sabathia declining with age, along with diminished velocity and stuff from Dallas Keuchel and Gio Gonzalez. The last four years have seen just three low-velocity left-handers put up three-win seasons, and the only pitcher with two such campaigns is Marco Gonzales, king of the soft-tossing lefties.

On June 2, Gonzales gave up 10 runs to the Angels on the heels of giving up eight runs to the Rangers. It ended a five-start stretch that saw him allow 30 runs in 24.2 innings. He struck just 15 batters and walked nine in that span. Still, due to a solid start to the year, his FIP stood at a decent 4.33 and his ERA was a little worse than average at 4.89. Since that game, roughly half a season of starts has passed and Gonzales has been one of the better pitchers in the game with an ERA and FIP both around 3.50 and his 2.3 WAR ranking 11th, just behind Justin Verlander and just ahead of Lucas Giolito. Gonzales isn’t a great pitcher, but he’s uniquely good, and this is the second straight season he’s accomplished that feat.

There are only 10 qualified starting pitchers in the game who put up a three-win season last year (3.4 for Gonzales) and have already eclipsed that mark this season (3.5 for Gonzales). Verlander, Max Scherzer, Patrick Corbin, Jacob deGrom, Trevor Bauer, and Gerrit Cole are the easier guesses. Zack Wheeler, Jose Berrios, and German Marquez are also in there along with Gonzales. His 6.9 WAR ranks ahead of only Berrios in that group, but it is worth mentioning even lowering the bar to two 2.5-WAR seasons in a row only adds Jake Odorizzi, Charlie Morton, Zack Greinke, Aaron Nola, Jon Gray, Kyle Hendricks, and Kyle Gibson. We are still talking about a relatively small group. Read the rest of this entry »

The 2019 Arizona Fall League rosters were (mostly) announced today, and we’ve created a tab on THE BOARD where you can see all the prospects headed for extra reps in the desert. These are not comprehensive Fall League rosters — you can find those on the AFL team pages — but a compilation of names of players who are already on team pages on THE BOARD. The default view of the page has players hard-ranked through the 40+ FV tier. The 40s and below are then ordered by position, with pitchers in each tier listed from most likely to least likely to start. In the 40 FV tier, everyone south of Alex Lange is already a reliever.

Many participating players, especially pitchers, have yet to be announced. As applicable prospects are added to rosters in the coming weeks, I’ll add them to the Fall League tab and tweet an update from the FanGraphs Prospects Twitter account. Additionally, this tab will be live throughout the Fall League and subject to changes (new tool grades, updated scouting reports, new video, etc.) that will be relevant for this offseason’s team prospect lists. We plan on shutting down player/list updates around the time minor league playoffs are complete (which is very soon) until we begin to publish 2020 team-by-team prospect lists, but the Fall League tab will be an exception. If a player currently on the list looks appreciably different to me in the AFL, I’ll update their scouting record on that tab, and I may add players I think we’re light on as I see them. Again, updates will be posted on the FanGraphs Prospects Twitter account, and I’ll also compile those changes in a weekly rundown similar to those we ran on Fridays during the summer.

Anything you’d want to know about individual players in this year’s crop of Fall Leaguers can probably be found over on THE BOARD right now. Below are some roster highlights as well as my thoughts on who might fill out the roster ranks.

Glendale Desert Dogs
The White Sox have an unannounced outfield spot on the roster that I think may eventually be used on OF Micker Adolfo, who played rehab games in Arizona late in the summer. He’s on his way back from multiple elbow surgeries. Rehabbing double Achilles rupturee Jake Burger is age-appropriate for the Fall League, but GM Rick Hahn mentioned in July that Burger might go to instructs instead. Sox instructs runs from September 21 to October 5, so perhaps he’ll be a mid-AFL add if that goes well and they want to get him more at-bats, even just as a DH. Non-BOARD prospects to watch on this roster include Reds righties Diomar Lopez (potential reliever, up to 95) and Jordan Johnson, who briefly looked like a No. 4 or 5 starter type during his tenure with San Francisco, but has been hurt a lot since, as have Brewers lefties Nathan Kirby (Thoracic Outlet Syndrome) and Quintin Torres-Costa (Tommy John). Dodgers righty Marshall Kasowski has long posted strong strikeout rates, but the eyeball scouts think he’s on the 40-man fringe. Read the rest of this entry »
