How On Earth Is Geraldo Perdomo Pulling This Off?

Eric Hartline-USA TODAY Sports

It seems like all of our coverage of the 2023 Diamondbacks here at FanGraphs has focused on the pitching, and it’s not hard to see why. Zac Gallen has looked phenomenal (at times historically so), Madison Bumgarner was abominable (eventually too abominable to roster), and the D-backs have given some intriguing young arms the chance to prove their worth in the big league rotation.

Yet all that being so, the real story of the 2023 Diamondbacks has been the offense. They lead the National League in hitting and rank third with 257 runs scored. They’re fourth in OBP, fourth in slugging percentage, and fifth in wRC+. By and large, the pitching staff has performed as expected – Gallen good, MadBum bad, everyone else somewhere in between – but the offense has been more potent than anyone could have envisioned.

It’s been a team effort in Arizona; among the nine Diamondbacks hitters with at least 100 PA, seven have been above-average at the plate. Corbin Carroll is off to the races. Lourdes Gurriel Jr. has taken a massive step forward. Ketel Marte and Christian Walker have been predictably solid, while Gabriel Moreno and Pavin Smith are holding their own. Leading the way, however, has been none other than Geraldo Perdomo, who is pacing the club in OBP, wRC+, and WAR. What? Read the rest of this entry »


St. Louis Cardinals Top 32 Prospects

Jeff Curry-USA TODAY Sports

Below is an analysis of the prospects in the farm system of the St. Louis Cardinals. Scouting reports were compiled with information provided by industry sources as well as our own observations. This is the third 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.

Haysed and Confused: What’s Fueling Austin’s Breakout?

Scott Taetsch-USA TODAY Sports

On Wednesday night, an eight-run seventh-inning outburst against the Yankees catalyzed another Orioles win, bringing their record to 32–17, second best in the majors. Among the highlights in the frame: Adam Frazier brought home three with a shot off the foul pole, and Gunnar Henderson plated two with a pinch-hit double. Understandably lost in the scrum was the first hit in the rally, a 109.6 mph scorcher off the bat of Austin Hays that snuck through the infield.

With two hits in four at-bats Wednesday, Hays brought his season slash up to .308/.351/.484 and his wRC+ to 131. The excitement that has come along with the Baby Birds — namely Henderson, Adley Rutschman, and Grayson Rodriguez — has overshadowed what looks to be a breakout season for the left fielder despite his own former prospect status. It’s easy to forget that back in 2017, Hays homered 32 times as a 21-year-old between High-A and Double-A, earning a call-up without a single Triple-A appearance. He was the first 2016 draftee to make the majors. Read the rest of this entry »


Carlos Correa’s Rebound From a Slow Start Has Stopped in its Tracks

Carlos Correa
Gary A. Vasquez-USA TODAY Sports

Carlos Correa has foot problems. No, we’re not talking about the concerns that scuttled his preliminary agreements on a pair of contracts in excess of $300 million this past winter. Those centered around the risk of future problems with his right foot, a legacy of the fractured fibula he sustained in 2014. Correa, who was scratched from the lineup for Tuesday’s game against the Giants and sat out Wednesday as well, is currently dealing with issues in his left foot and is likely to wind up on the injured list, stalling his recovery from a very slow start to his second season with the Twins.

On Monday night at Target Field, Correa roped a double to left field off the Giants’ Sean Manaea. He came into second standing up, but as he explained on Tuesday, he took an odd step rounding first base, whereupon his left heel began to bother him. He gutted out the remainder of the game but was in more pain the following morning and, after undergoing an MRI that revealed inflammation in his heel, was scratched from Tuesday’s game.

On Wednesday, Correa was diagnosed with a muscle strain in his left arch as well as plantar fasciitis, the inflammation of the thick band of tissue that connects the heel bone to the toes. The team has not decided whether he’ll be placed on the IL, and at least as of Tuesday, he harbored hopes of returning for this weekend’s series against the Blue Jays. Manager Rocco Baldelli was less sanguine, telling reporters, “I think we get to Friday and some of our decisions might be made for us.”

Even leaving aside the strain, plantar fasciitis isn’t something that’s going to dissipate in a couple of days. The Baseball Prospectus Recovery Dashboard contains 13 instances of players going on the IL for plantar fasciitis since 2016 (though none for 2020). Those 13 stints averaged 35 days, with a low of 12 (John Lackey in 2016), a median of 30, and a high of 85 (Harrison Bader last year).

Again, this is the opposite foot from the one that led the Giants and the Mets to pull their respective offers — 13 years and $350 million for the former, $12 years and $315 million for the latter — due to concerns that emerged during his pre-signing physicals this past winter. Those concerns could be traced back to 2014, when as a 19-year-old prospect at High-A Lancaster, Correa caught his cleat in a base as he slid, fracturing his right fibula, damaging ligaments, and requiring the surgical insertion of a plate in his ankle. Though he’s never missed a major league game traceable to those injuries, both teams got spooked. Once the Mets backed away, Correa returned to the Twins, with whom he spent 2022, via a six-year, $200 million deal that has vesting and club options that could reach a maximum value of $270 million over 10 years.

While Correa’s current woes aren’t related to those previous concerns, the fact does remain that he’s had a hard time staying on the field. He’s topped 150 games only once, playing 153 as a 21-year-old in 2016, and averaged just 116 games in the five non-pandemic seasons since. What still appears to be a Hall of Fame career in the making thanks to his excellent play at a young age — early in his age-28 season, he’s already tied for 34th in JAWS at the position, 10 spots ahead of Omar Vizquel, and could pass the likes of Miguel Tejada and Nomar Garciaparra by the time he’s 30 — can only withstand so many roadblocks on the way to Cooperstown.

If Correa winds up on the IL, he’ll fall short of 150 games again. Even if he misses a comparatively short amount of time — six of the 13 stints were 20 days or fewer — that’s a blow to the Twins, who at 26–24 lead the AL Central by three games but have been in a slide lately. After going 17–12 in March and April, they’re 9–12 this month and had lost three in a row and five out of six before beating the Giants, 7–1, on Wednesday. Kyle Farmer started at shortstop, as he had done on Tuesday and April 9–12, when Correa missed four games due to back spasms. Even with those outages, Correa entered Thursday tied with Byron Buxton for the team lead in plate appearances (192) and 41 innings ahead of any other Twin in defensive innings (376.1).

That said, Correa has been off to a slow start, hitting just .213/.302/.396 with six homers and a 94 wRC+, though lately he had been trending upwards, with a .227/.326/.453 (114 wRC+) line in May after a dismal .202/.283/.351 (77 wRC+) line in April. His numbers have improved notably since the point just over two weeks ago when he had a .185 batting average and conceded, “I’d boo myself, too, with the amount of money I’m making if I’m playing like that and I’m in the stands.”

Correa’s .244 xBA and .410 xSLG suggest his overall numbers should be at least a bit better. On Monday, Esteban Rivera examined the shortstop’s early-season struggles, pointing out that his Statcast percentile rankings — 67th for hard-hit rate, 80th for barrel rate, 94th for maximum exit velocity, with only a 50th percentile for average exit velo out of the ordinary — offer reassurance that he’s still hitting the ball hard. He’s hitting to the opposite field more often (32.8%, well above his career 27,1%), though Rivera was able to tease out of the data the likelihood that a flatter swing and contact deeper within the strike zone are contributing to less impactful contact even when pulling the ball — a matter of timing, but probably a transient one.

The whole piece is worth a read. One thing I will note is that Correa’s oppo/pull imbalance was really an April thing (30.8% pull rate, 45.8% oppo) that had disappeared this month (47.2% pull, 15.1% oppo). Here’s a look at his rolling 15-game rates over the past two seasons:

And here’s a look at his rolling xwOBA:

Beyond his performance, Correa’s injury comes at a particularly inopportune time for the Twins. Second baseman Jorge Polanco, utilityman Nick Gordon, and corner outfielders Trevor Larnach and Max Kepler are all on the 10-day IL, and none has a clear timetable to return. Kepler and Polanco both have left hamstring strains, though both are considered mild. Larnach is battling pneumonia. Gordon is out with a fractured right tibia sustained when he fouled a ball off his leg and will be down for quite awhile. Additionally, Joey Gallo missed Wednesday’s game due to left hamstring soreness but is hoping to avoid an IL stint.

In Correa’s absence, the Twins are likely to continue rolling with Farmer, who’s currently hitting .274/.326/.405 (105 wRC+) and has split his time between third base, second base, and shortstop. The Twins acquired the versatile 32-year-old from the Reds with the belief that he would be their shortstop this year after Correa opted out of his contract, one year into the three-year, $105.3 million deal he signed shortly after the lockout ended in March 2022.

Given the slew of injuries, it’s worth noting that as of next Monday, Royce Lewis will be eligible for activation. The first pick of the 2017 draft tore his right ACL for the second time in a year and a half last June, just 12 games into his first stint in the majors (and three innings into his first major league appearance in center field), during which he hit an impressive .300/.317/.550 in 41 PA. While it’s tantalizing to imagine the Twins taking the wraps off of a player who placed 55th on our Top 100 Prospects list this spring, Lewis has just eight games of his rehab stint under his belt, the last six at Triple-A St. Paul, and while he’s hitting .333/.375/.700 through 32 PA, the Twins don’t sound inclined to rush him back. “We’ll see what he’s doing when the rehab assignment comes to an end and we have to make a decision, or whenever that time is when he’s physically and repetition-wise ready,” Baldelli said. More, via TwinCities.com:

“If Byron Buxton goes on the IL, the first day Byron Buxton is ready to come back, he’ll be back — and he’ll be hitting second or third or fourth. Correa, something similar,” Baldelli said. “But Royce, I can’t put Royce or any young player in that same type of conversation.

“He’s playing well right now, I think he’s swinging the bat well. He’s physically doing just as we would have hoped.”

If Correa does require an IL stint, obviously that increases the likelihood of Lewis turning up in the near future. In the meantime, the Twins have a difficult stretch of games ahead of them, with five of their next six series against teams with winning records: the Blue Jays (six games), Rays, Astros, and Brewers. The other is against the Guardians, who are just 21–28 and 4.5 games out of first in the AL Central but are probably the biggest threat to Minnesota in the division. If they’re lucky, the Twins will have Correa’s help for at least some of that.

Checking In on the Toronto Outfield

Kevin Kiermaier
Nick Turchiaro-USA TODAY Sports

I don’t know about you, but I was very excited about the Blue Jays’ outfield coming into this season. In December, the team signed veteran defensive wizard Kevin Kiermaier to take over in center field, pushing incumbent George Springer to right. Just a few weeks later, they sent catcher Gabriel Moreno to the Diamondbacks so that young defensive wizard and all-around rising star Daulton Varsho could play left. If you’re keeping score at home, that makes one George Springer and two defensive wizards. Most teams don’t have two defensive wizards. There just aren’t that many wizards running around, and the ones who play baseball tend to prefer the infield. The Blue Jays had three center fielders, two of whom were well-respected veterans with long track records on successful teams, two of whom were coming off four-win seasons, and two of whom could reasonably claim to be, when healthy, the best defensive outfielder in all of baseball. That’s a pretty exciting Venn diagram.

Brent Suter Is at It Again. Bring a Mop and Bucket.

Brent Suter
Charles LeClaire-USA TODAY Sports

Back in March, I used the Rockies’ signing of Brad Hand as an entry point into an interesting trend: the Rockies were stockpiling soft-tossing lefties. A couple weeks later, I went to Scottsdale and talked to Austin Gomber. And now I’m writing about the Rockies’ pitching staff again. And not their erstwhile no. 1 starter (Kyle Freeland) nor their closer (Pierce Johnson) nor the guy who was supposed to be the closer (Daniel Bard) nor the hard-throwing setup guy with the goofy slider (Justin Lawrence). I’m writing about Brent Suter, another finesse lefty. The most soft-tossin’ lefthander in all the land, as a matter of fact.

Why? Because I can, mostly. If you’re tired of reading about the Rockies’ bullpen, write your Congressperson. They can’t stop me either. But also because Suter seems to have cracked it. This 33-year-old, whose fastball is so slow passing motorists would give it the finger for holding up traffic in parts of Texas, has been one of the best relief pitchers in baseball this year.

Logan Gilbert Details His Switch From a Change to a Split

Bill Streicher-USA TODAY Sports

Logan Gilbert discussed his new changeup in detail when he was featured here at FanGraphs 12 months ago. Not satisfied with the one he’d been throwing, the Seattle Mariners right-hander had gone to “more of a traditional circle,” a grip he felt would yield better command and consistency. His stated goals included upping the pitch’s usage from 8% (it had been 7.8% in 2021) to 10-15%.

A certain amount of success followed — opposing hitters batted .125 with a .122 wOBA against the pitch — but Gilbert’s goals went largely unmet. The 6-foot-6 hurler never felt completely comfortable with the revamped offering, and by season’s end, his changeup usage was still a meager 8%. Instead of becoming a reliable weapon, it remained little more than an infrequently used, hit-or-miss option in his arsenal.

As pitching nerds are wont to do — and Gilbert certainly qualifies as such — he went back to the drawing board. The righty traded in his circle change for a splitter over the offseason, and the results have been just what he was looking for. He has been comfortably throwing his new weapon 12.7% of the time, and it has yielded a paltry .111 batting-average-against and an equally impressive .111 wOBA.

Gilbert explained the successful transition from his changeup to his splitter when Seattle visited Boston last week. Read the rest of this entry »


Effectively Wild Episode 2011: Who Was That Mascot Man?

EWFI
Ben Lindbergh and Meg Rowley banter about the major leagues’ sudden influx of 24-year-old right-handed pitchers with the surname “Miller,” the Rays’ surprisingly precarious position in the AL East (7:48), and the Cubs, the Brewers, and the state of the NL Central (12:45), before focusing their bat-resuscitating powers on Trea Turner (17:22), with almost immediate effect. Then they talk to David Raymond, the original Phillie Phanatic performer, Gritty co-conceiver, frequent team mascot consultant, and founder of the Mascot Boot Camp and Mascot Hall of Fame, about all of their mascot questions, the mascot design process, and what it’s like to be inside a mascot costume, plus updates and a Past Blast from 2011 (1:26:54).

What’s the Matter With Alejandro Kirk?

Alejandro Kirk
Nick Turchiaro-USA TODAY Sports

The 2022 Blue Jays won 92 games and finished second in the American League in runs scored, and Alejandro Kirk had a lot to do with that. Hitting .285/.372/.415 and playing better defense behind the plate than most expected when he was a prospect, he formed a dynamite catching chimera with Danny Jansen and Gabriel Moreno, who was sent to Arizona this offseason. The resultant pairing of Kirk and Jansen projected to give the Blue Jays the best catching situation in baseball in 2023. But while the rest of the top catchers in the majors have worked out about as expected, Toronto’s have not, combining to hit a respectable but disappointing .232/.311/.384. As the younger and much less experienced of the two, with more time to grow as an offensive player, Kirk’s struggles concern me more.

It’s easy to forget how quickly Kirk rocketed through the minors in recent years. After playing mostly in High-A Dunedin in 2019, the Blue Jays were interested enough in his talent to put him on the taxi squad at the start of September 2020, even getting him into nine games, seven as a catcher. The following season, he only played a couple of weeks at Triple-A Buffalo before becoming a permanent major leaguer. While a promotion that aggressive does happen once in a while, there’s no situation that I can remember in which a team promoted a catcher who wasn’t an extremely polished defender that quickly. He hit .242/.328/.436 — a solid triple-slash for any catcher, but exciting for a player with such little high-level experience. Perhaps as importantly, while Kirk didn’t fool anyone into thinking he was the next Yadier Molina with the glove, he played far better defensively than the DH-pretending-to-be-a-catcher archetype that players like Zack Collins fall into. But Kirk’s .234/.353/.324 line so far is not what people expected in the follow-up season, and while the resulting wRC+ of 96 is far better than trainwreck status, it’s also far from the stardom he displayed last year.

When you see a dropoff like that, especially in a fairly short stretch of games, you frequently see a BABIP blip along with it. But while Kirk has dropped about 40 points of BABIP since last year, his hit profile supports a fairly low BABIP. In fact, ZiPS thinks that he’s “earned” a .249 BABIP based on how he’s hit this year, lower than his actual BABIP of .261. The plate discipline stats also show no red flags; he still makes good contact and isn’t suddenly offering more often at worse pitches.

The icky part of Kirk’s seasonal line involves the loss of power, and unfortunately, the drop in both his exit velocity and loft is real; four miles per hour and seven degrees of launch angle are not small deviations. For the Statcast era, I took every player who put 75 pitches into play in consecutive years, ranked their dips in exit velocity and launch angle (out of 2,389 players), and found those with the biggest dropoffs, using the average of their ranks (we’re trying to get a general idea, so a very simple method is fine). Here are the results:

Largest Launch Angle/Exit Velocity Droppers

Jonathan Lucroy 2016-2017 -2.6 -6.6 195 44

Paul DeJong 2020-2021 -2.9 -5.3 147 106
Jed Lowrie 2015-2016 -3.3 -4.8 102 158
Carlos González 2018-2019 -2.3 -7.3 233 30
Christian Yelich 2020-2021 -3.4 -4.5 88 183

Kirk ranks highly in terms of dropoff in these stats, so it’s not surprising to see his power evaporate. It’s also not something that bodes well. ZiPS and other projection systems deal with these issues in a more scientifically sound fashion than this, but there are a lot of fading players on this list. The ones that did improve overall in seasons after the two-year window, such as Díaz and Acuña Jr., managed to reverse this process. I went down the top 50 players on this list and found that this held true as well. And Kirk actually showed some dropoff from 2021 to ’22 despite his excellent performance, suggesting that the seeds of a future issue had already been sown.

One culprit here is that he is simply topping hard pitches down in the zone, whereas last year he was getting just enough loft to squeeze a bunch of hits out of them; he hit .452 on low fastballs and lifted the majority of them with a positive launch angle. This season, only three of 13 low fastballs haven’t been driven into the ground, and Kirk has lost about eight degrees of launch angle on average compared to last year. It’s not just luck either: he’s hitting them with less velocity, resulting in an xBA of .231 compared to .336 last year.

The exit velocity issue is important for Kirk because he’s not a fast player and hits a lot of grounders; he’s not going to be legging out many soft infield hits, so he needs to hit the ball hard. Groundball BABIP is very sensitive to exit velocity, as unlike fly balls, there’s no sweet spot where a soft hit becomes an impossible-to-field bloop.

BABIP by Hit Type and Velocity, 2021-2023
Exit Velocity GB BABIP LD BABIP FB BABIP
95+ mph .364 .659 .157
90-94 mph .235 .550 .036
85-89 mph .197 .542 .020
80-84 mph .160 .590 .029
75-79 mph .139 .677 .104
<75 mph .162 .588 .609

And if you check the Statcast leaderboard in terms of year-to-year change, Kirk is near the top of the list in terms of most increased topped contact rate.

The good news is that the full model of ZiPS is aware of these hit tendencies and still thinks Kirk is going to be alright over the long haul, though his problems right now have increased the downside risk, pushing his projections down from the 3.5–4.0 WAR range they were in before the season:

ZiPS Projection – Alejandro Kirk
Year BA OBP SLG AB R H 2B 3B HR RBI BB SO SB OPS+ DR WAR
2024 .261 .350 .405 410 48 107 20 0 13 56 55 57 0 110 2 2.9
2025 .260 .349 .407 420 49 109 20 0 14 58 57 57 0 111 3 3.0
2026 .257 .347 .405 420 49 108 20 0 14 57 57 56 0 109 3 3.0
2027 .258 .347 .407 415 48 107 20 0 14 56 56 54 0 110 3 3.0
2028 .254 .345 .398 405 46 103 19 0 13 54 55 53 0 107 2 2.7
2029 .251 .341 .389 391 44 98 18 0 12 51 53 51 0 104 2 2.4
2030 .249 .339 .382 374 41 93 17 0 11 48 50 49 0 101 1 2.1

These types of changes aren’t good, but they’re also not death sentences for careers and can be reversed. Kirk, even while struggling, still retains a lot of the characteristics that made him such a good hitter last year. The key to improving his baseball game right now may be working on his golf game and re-embracing the modern trend of turning low pitches into long drives rather than worm-burners.
