Mike Yastrzemski Talks Hitting

Allan Henry-USA TODAY Sports

Mike Yastrzemski became a good hitter through a lot of hard work, but it didn’t hurt that he had a good tutor growing up in Danvers, Massachusetts. The San Francisco Giants outfielder is the grandson of Carl Yastrzemski, who logged 3,419 big league hits, including 452 home runs, on his way to the Hall of Fame. A late bloomer who didn’t make his big league debut until he was 28 years old, the younger Yastrzemski may never come close to those numbers, but he is nonetheless a quality hitter. Now in his fifth season, all with the Giants, the 32-year-old Vanderbilt product has a 115 wRC+ and 74 round-trippers in 1,742 career plate appearances.

Yastrzemski — 5-for-14 with four extra-base hits so far this season — talked hitting late in spring training.

———

David Laurila: Let’s start with one of my favorite icebreaker questions: Do you view hitting as more of an art or as more of a science?

Mike Yastrzemski: “It’s definitely an art. You can have all the science in the world and it doesn’t make you a good hitter. You can have every angle, you can have every exit velo… again, that’s not going to make you a good hitter. Can it help you? Definitely. But I don’t see it as as much science-based as I see it as an art.” Read the rest of this entry »


What the Frig Is Brent Honeywell Jr. Throwing?

Mark J. Rebilas-USA TODAY Sports

There’s a lot to love about how the Padres built their roster, and I’m not talking about the obvious stuff like trading for Juan Soto or building a lineup entirely of shortstops or sneaking Xander Bogaerts out of Boston under the fuel tank of an Isetta bubble car. I’m talking about how they built their pitching depth. It’s a smorgasbord of guy-remembering, a combination of starters from the 2010s who are just hanging on and top prospects from the 2010s who are still trying to break through.

Look at the pitching staff of the 2023 El Paso Chihuahuas: Cole Hamels, Jay Groome, Julio Teheran, Anderson Espinoza, Aaron Brooks, and (pounds table) Wilmer (pounds table) Jetpacking (pounds table) Font! In a ranking of expensive San Diego-based nostalgia trips, I did not think anyone would beat Top Gun: Maverick so soon, but here we are.

One of those 2010s late bloomer prospects broke camp with the big league club. Brent Honeywell Jr., who not so long ago was one of the most interesting pitchers in the high minors, has now made two appearances in the majors for the Padres. Read the rest of this entry »


Anthony Volpe Brings the Vault Lead to MLB

Anthony Volpe
Brad Penner-USA TODAY Sports

I went to my first game of the season this past weekend: the Yankees hosting the Giants on a beautiful Saturday afternoon in the Bronx. In the bottom of the second inning, Anthony Volpe came up to the plate against Alex Cobb and hit an 0–2 slider into left field for his first career hit, drawing a standing ovation from the folks in attendance.

After his hit, Volpe got to moving on the basepaths. In 2022, he swiped 50 bags over 132 games between Double and Triple-A. The limited pickoffs rule and bigger bases aided him, but like any good base stealer, he took advantage of pitchers with slow deliveries and/or catchers with poor pop times whenever he could. As we’ve learned from the first week of games, the combination of those factors can create an ideal environment for aggressive runners. But there is one thing that Volpe does that makes him different from your normal base stealer: the vault lead. Read the rest of this entry »


Miguel Vargas Is Making Waves by Standing Still

Miguel Vargas
Jonathan Hui-USA TODAY Sports

Miguel Vargas couldn’t swing. I don’t mean that in the insulting way that little leaguers sometimes do — “hey batter, you’ve got nothing, you can’t even swing.” I mean that he was medically prohibited from swinging. That didn’t stop the Dodgers from playing him this spring, as Davy Andrews detailed for this very site last month. It did mean, however, that he had to watch every pitch thrown to him, ball or strike, and simply take it. Not exactly the way he expected to enter his first spring training with a big league job nailed down, I’m sure.

The pinky finger fracture that kept Vargas from swinging has healed, but you might not know it from his batting line so far this year, because it seems he took that lesson to heart. Five games into his 2022 season, he’s come to the plate 18 times. In nine of those plate appearances, he’s walked. That 50% walk rate is amazing on its own, and I’ll come back to that, but the way he’s gotten to it is downright stunning.

The key to walking a lot is not swinging at bad pitches, and Vargas is doing that to a fault. Per Statcast, he’s swung at four of the 50 pitches he’s seen outside the strike zone in 2023. That’s the best rate in the majors, which is impressive on its own; 205 batters have seen at least 25 pitches outside the strike zone already this season, and every single one of them has swung at them more frequently than Vargas. We’re talking all the various plate discipline geniuses already enshrined in the pantheon of good eye; they’re all looking up at Vargas’ extreme selectivity. Read the rest of this entry »


Making Sense of the Braves’ Shortstop Situation

Orlando Arcia
Brad Mills-USA TODAY Sports

On Opening Day, when the Braves took the field after batting in the top of the first inning, everyone you’d expect ran out to their usual positions. Well, almost everyone. Taking his position as the starting shortstop was Orlando Arcia, the recipient of a three-year contract extension announced earlier that day. The deal is worth $7.3 million with a club option for a fourth year that includes a $1 million buyout and replaces the previous two-year contract extension he had signed after the 2021 season.

If you hadn’t followed the Braves’ shortstop saga over the offseason, seeing Arcia in the Opening Day lineup might have been a surprise. So let’s recap: Dansby Swanson, the everyday shortstop since his debut in August 2016, played out his final year under team control last year and entered free agency. Atlanta didn’t show much interest in re-signing him once he hit the open market, and he wound up inking a massive seven-year deal with the Cubs.

The heir apparent to Swanson was Vaughn Grissom, who had been called up midseason to fill in for an injured Ozzie Albies even though he hadn’t played above Double-A yet. He impressed with a 165 wRC+ through his first 100 plate appearances in the big leagues, but that mark slid to just 35 over his final 50 trips to the plate. His late swoon was so bad that the Braves ended up benching him in three of their four postseason games. Still, entering spring training, the expectation was that Grissom would get every opportunity to win the job for good.

For his part, Arcia had appeared in just 104 games for the Braves after they acquired him from the Brewers in April 2021. He played four different positions in the infield and outfield, essentially acting as a utility man for Atlanta — a pretty significant step backwards after beginning his career as Milwaukee’s starting shortstop. Through his first five seasons, he put up a .244/.295/.366 slash line (a 71 wRC+) and accumulated 1.9 WAR, and after joining the Braves, he spent a lot of time riding the shuttle between Triple-A and the majors. Still, he did show some improvement at the plate in Gwinnett, posting a 129 wRC+ in 322 PA with his best-ever ISO at .233.

Those improvements at the plate carried over to the next year, where Arcia spent nearly all of his time in the big leagues as the Braves’ utility man. In limited action, he posted a 104 wRC+, a career-high for him. The biggest difference for him was a jump in batted ball quality:

Orlando Arcia, Batted Ball Peripherals
Year EV FB+LD EV Barrel% Hard Hit% GB% ISO wRC+
2016–20 87.0 91.1 3.3% 30.1% 52.0% 0.121 71
2021 88.2 90.7 3.2% 38.1% 50.8% 0.111 49
2022 90.7 93.7 7.5% 42.5% 45.9% 0.172 104

His hard-hit rate improved by more than four points, up to 42.5%, and his barrel rate reached 7.5%, both career highs. He also cut his popup rate to 5.6% and simultaneously increased his fly ball rate. By elevating his higher quality contact but avoiding mis-hits, he was able to generate much more productive results on his balls in play, with average exit velocities on his fly ball and line drive contact that were particularly notable. Instead of a light-hitting, defense-first shortstop, Arcia’s batted ball contact started looking a lot more dangerous.

His plate discipline also took a big step forward. With the Brewers, Arcia had developed a very aggressive approach at the plate which didn’t go well with his middling bat-to-ball skills. Last year, he reduced his swing rate to 44.7%, a drop of nearly eight points over the year prior, and easily a career low. His contact rate didn’t budge, but simply taking more pitches allowed him to run a 9.0% walk rate and maintain his decent strikeout rate.

Despite those improvements at the plate, it still came as a surprise to see Arcia win the Opening Day gig. Grissom had an excellent spring, and a surprise contender emerged in Braden Shewmake.

Braves Shortstops in Spring Training
Player PA H K% BB% OPS
Orlando Arcia 47 14 19.1% 12.8% 1.011
Vaughn Grissom 40 13 10.0% 5.0% .829
Braden Shewmake 35 10 17.1% 5.7% .823

There’s only so much stock you can put into spring numbers, though there is some evidence that exit velocity improvements can be a little sticky into the regular season. Unfortunately, based on the limited number of Statcast tracked batted balls, Grissom struggled with the same issues that undercut his seemingly impressive debut last year. In 15 tracked batted balls, his average exit velocity was just 86.5 mph — slightly better than the 84.6 mph he put up in the big leagues last year, but still well below league average. (Arcia only had eight tracked batted balls this spring, but their average exit velocity was 94.2 mph.) The lack of high quality hard contact last year was a major red flag for Grissom, who only managed a 34.3% hard-hit rate and put nearly half of his batted balls on the ground. A lot of his success was BABIP-driven, which is why he crashed so hard in September when balls stopped finding gaps in the defense.

Then there’s the problem of Grissom’s defense. He wasn’t great at second base while filling in for Arcia, costing the Braves five outs and three runs per OAA and RAA. At the more challenging defensive position, it’s likely those numbers would only get worse. Grissom worked out with Ron Washingon, who helped turn Marcus Semien’s defense into a strength, for three separate weeks during the offseason. But while there was some improvement, it wasn’t enough to warrant handing him the job out of the gate.

Shewmake’s emergence may have complicated the picture a little, but he wound up getting sent back to Triple-A for more development time. A decent defender already, the thing holding him back has been his lack of production at the plate. He has a good feel for putting the bat on the ball but no power whatsoever and limited on-base skills. His improvements this spring had coaches buzzing, but ultimately, he needs to prove it in the minors before getting a shot in the big leagues, and his ceiling may be that of a utility infielder anyway. After both Grissom and Shewmake were sent down to the minors, it’s telling that the former lined up at shortstop for Gwinnett, with the latter shifting over to second base.

Despite all this drama surrounding the position this offseason, Grissom could end up being the Braves’ shortstop of the future anyway. The extension Arcia signed doesn’t preclude the Braves from calling up him or Shewmake if they break out in the minors this year. But Arcia is only 28 years old, and it’s possible he’s in the middle of a mid-career breakout after his change of scenery. The improvements he’s made at the plate are a move in the right direction, and his defense is another positive at a premium position. If Grissom does get called up at some point to take the starting role, having Arcia as a utility man isn’t the worst outcome for the Braves.

Madison Bumgarner’s 2023 Is Off to a Rough Start

Madison Bumgarner
Jonathan Hui-USA TODAY Sports

Once upon a time, a Clayton KershawMadison Bumgarner matchup would have been a sight to behold. But when the two lefties squared off on Saturday evening in Los Angeles, it was a decidedly one-sided affair. Kershaw dominated the Diamondbacks, allowing one run and striking out nine over six innings; Bumgarner, meanwhile, was pummeled for five first-inning runs and lasted just four frames. It was the latest in a long line of disappointing performances since the former Giants ace joined the Diamondbacks.

Bumgarner was on the ropes from the beginning. He served up a double to Mookie Betts on his fifth pitch of the game, hit Max Muncy to load the bases with one out, walked the bases loaded after Chris Taylor’s sacrifice fly scored Betts, and gave up a grand slam to Trayce Thompson, who would later add homers off relievers Kevin Ginkel and Carlos Vargas.

By the time the dust had settled, Bumgarner had thrown 31 pitches and was down 5–0. The 33-year-old lefty did pull himself together enough to follow with three scoreless innings, allowing one baserunner in each, but he finished with four walks and four hits allowed, striking out just two and getting just five swings and misses. Including his 10 called strikes, his 17.6% CSW was his fifth-lowest mark from among his 66 starts as a Diamondback; his low was 15.2% (eight called strikes, two swinging strikes in 66 pitches) in a September 27, 2020 start against the Rockies, in which he at least posted five shutout innings, netting his only win of the pandemic-shortened campaign.

Saturday’s bad news went beyond that meager CSW rate. For one thing, old friend Eno Sarris suggested that Bumgarner and Ginkel were tipping pitches:

Even if that hadn’t been the case, the average velocity of Bumgarner’s pitches was down by nearly two miles per hour relative to last year:

Madison Bumgarner Velocity Comparison, 2022–23
Year 4-Seamer Cutter Curveball Changeup Slider
2022 91.2 87.4 78.6 85.5 83.3
2023 89.1 85.8 76.7 83.7 84.4
Change -2.1 -1.6 -1.9 -1.8 +1.1
SOURCE: Baseball Savant

You can safely ignore that positive bump on Bumgarner’s slider, as he threw just one on Saturday. Additionally, the spin on his four-seamer averaged just 2,041 RPM, down 162 from last year and 184 from his final start of the spring, on March 27 against the Guardians. The pitch also got 2.7 inches less horizontal break than last year’s model. The Dodgers didn’t actually do any damage off of Bumgarner’s four-seamer, though hitters last year destroyed it to the point that it was the majors’ second-least valuable pitch according to Statcast:

If all of this sounds like a pitcher who’s Physically Not Right, the thought crossed the minds of the Diamondbacks. On Sunday, the team sent the 33-year-old lefty back to Phoenix to be evaluated by team doctors, with manager Torey Lovullo telling reporters, “Bum was talking about fatigue postgame last night.” More via MLB.com:

“Information was kind of coming in slowly and we just thought it’d be the best thing for him to get back to Phoenix where our doctors can get a look at him. On the urgency scale, I don’t think it’s very high, but it’s all precautionary at this point.”

“There was nothing major from his standpoint,” Lovullo said Saturday night. “It was more just us asking questions and trying to find out if everything is OK. There was looseness to the breaking ball, and things just weren’t consistent. He’s always around the zone, but there were some big misses today. Red flags go up when we see that, our eyes tell us a story, but Bum was OK.”

Bumgarner underwent an MRI that showed no structural damage, and as Lovullo said before Monday night’s game, he’s on track to make his next start, likely Friday against the Dodgers at Chase Field. But even if he’s got the green light physically, that’s a long way from finding reasons to be particularly optimistic about his 2023 chances. The former World Series hero is coming off a season in which he pitched to a 4.88 ERA and 4.85 FIP in 158.2 innings and set full-season lows with his 16% strikeout rate and 9% strikeout-walk differential (he was 0.2 points lower in both categories in 2020). Meanwhile, his 9.8% barrel rate and 42.8% hard-hit rate were both full-season highs for the Statcast era. Though he made 30 starts for just the second time since 2016, his 0.5 WAR was the second-lowest among pitchers with 30 or more starts, ahead of only the Mariners’ Marco Gonzalez (0.1).

Since joining Arizona via a five-year, $85 million deal in December 2019, Bumgarner has put up a 5.06 ERA and 5.08 FIP in 350.2 innings, netting just 1.2 WAR. Highlighted by a seven-inning hitless outing that didn’t count as an official no-hitter, his best work came in 2021, when he pitched to a 4.63 ERA and 4.67 FIP in 146.1 innings en route to 1.5 WAR; he missed over six weeks that year due to shoulder inflammation, and while he pitched better after the injury than before, his career has continued its downward trajectory.

Indeed, as measured by Stuff+, the quality of Bumgarner’s pitches has been deteriorating:

Madison Bumgarner Stuff+, 2020–23
Season Stf+ FA Stf+ SI Stf+ FC Stf+ CU Stf+ CH Stuff+
2020 92 98 95 75 107 90
2021 86 80 105 102 57 94
2022 80 95 100 87 57 86
2023 66 102 76 72 82

Woof. Obviously you can take this year’s one-game sample with a grain of salt, but as Sarris, the model’s co-creator, wrote, the fastball Stuff+ does capture some signal at this level. Aside from his cutter, which he throws about 28% of the time, Bumgarner doesn’t have a pitch that’s consistently average or better, and at this point, one has to wonder what exactly he and the Diamondbacks, for whom former Astros pitching coach Brent Strom now works, are doing to reverse this rather dismal trend. In an age when pitchers reinventing themselves with new offerings or refinements of old ones seems like a constant, why is none of this is happening for Bumgarner?

On a team that aspires to break .500 for the first time since 2019 but that projects for just 78.4 wins via our preseason Playoff Odds, Bumgarner now stands out as one of the weak links. The Diamondbacks’ rotation placed just 23rd in our Positional Power Rankings, with six Arizona starters — staff ace Zac Gallen, veteran righties Zach Davies and Merrill Kelly, rookie Ryne Nelson, and prospects Brandon Pfaadt and Drey Jameson — all forecast to exceed Bumgarner’s projected 0.3 WAR, the last three of those each with 40–100 fewer innings. In other words, the case that he is one of the Diamondbacks’ best five starters relies upon some combination of reverence for his track record, a desire to justify a contract that looks like a sunk cost, and a need for prospects to get more seasoning. Bumgarner’s World Series exploits are the stuff of legend, but since spraining his AC joint in a 2017 dirtbike accident that cost him three months, he’s managed just a 100 ERA- and 108 FIP- and reached 30 starts only twice. Going by batted ball stats, he’s had an xERA of 5.53 or higher in every season with the Diamondbacks save for 2021.

Bumgarner is the Diamondbacks’ highest-paid player, owed $23 million for this year and $14 million for next year, but at best he looks more like a guy who can eat 140–150 innings at the back the rotation. It’s understandable why he’s begun the year in the starting five as Arizona breaks in Nelson, uses Jameson out of the bullpen, and farms out Pfaadt, who made just 10 starts at Triple-A Reno last year. But if the Diamondbacks are going to turn the corner, they’ll have to reckon with what the 2023 version of Bumgarner can give them. Right now, that doesn’t look like a whole lot.


Adam Frazier Looks Back Fondly on Pittsburgh (But Not the Losing)

Adam Frazier
David Butler II-USA TODAY Sports

Adam Frazier is off to a hot start with the Baltimore Orioles. Signed as a free agent over the offseason, the 31-year-old infielder/outfielder went 5-for-8 with three doubles, a home run, and a stolen base in his first series of the season. A National League All-Star in 2021 when he slashed .305/.368/.411 with the Pittsburgh Pirates and San Diego Padres, he is now in his eighth big-league season and his 11th in pro ball; Pittsburgh selected the left-handed hitter in the sixth round of the 2013 draft out of Mississippi State University.

Frazier had no idea what to expect on draft day. The erstwhile Bulldog — his teammates at the SEC school included Kendall Graveman, Hunter Renfroe, and Brandon Woodruff — had talked to scouts from most MLB teams and “didn’t really have a feel” for where he’d be going. It nearly ended up being Houston.

“We were in Virginia to play a Super Regional,” Frazier explained. “It was the day before the game, and the draft was going on during our practice. It was basically ‘have your phone on you and see what happens.’ My agent called. The Astros actually wanted to draft me, but they were offering under slot. I was like, ‘Tell them no, unless they want to do slot.’ I fell from there and ended up going to Pittsburgh.”

Houston, which had the first pick in the sixth round, ended up selecting Jacob Nottingham. The Pirates then took Frazier with the 13th pick. As an Oriole, he now has a tie-in to the could-have-been: Baltimore GM Mike Elias was in Houston’s front office at the time, as was assistant GM Sig Mejdal. Read the rest of this entry »


Lessons From 11 Years of Darin Ruf

Darin Ruf
Wendell Cruz-USA TODAY Sports

The actual process of cutting a major league baseball player on a guaranteed contract is easy enough in theory, but time-consuming in practice. The Mets designated Darin Ruf for assignment last Monday and had likely known he wouldn’t make the team for at least a couple weeks before that. But it wasn’t until this Monday that the 36-year-old former Creighton Blue Jay finally received his release. That ends the fifth act in Ruf’s career, one everyone would probably just as soon forget.

Ruf was one of several first base/DH types who passed through waivers just before the season, as teams weighed the potential for a bounceback against the downside of being on the hook for $3 million in his case, plus another $250,000 to buy out his club option in 2024 if things didn’t go well. Perhaps he’ll be more attractive at the league minimum or as depth in Triple-A if he accepts such an assignment, and we’ll see him in the majors again.

Even if this is the end of Ruf’s time as a major leaguer, he’s had a noteworthy career, spanning 561 games over parts of eight seasons across 10 years, on either side of a dominant three-year run in the KBO. I, for one, did not expect to be writing about Ruf in 2023, but he’s confounded my expectations and then some. Read the rest of this entry »


Szymborski’s 2023 Bust Candidates: Pitchers

Corey Kluber
Eric Canha-USA TODAY Sports

Today, we we wrap up my yearly breakouts/bust series with the pitchers I’m pessimistic about in 2023 to some degree. Since any breakouts or busts beyond what a projection system suggests are naturally going to be low-probability outcomes, there’s a high probability of me looking pretty silly — something writers try to avoid. Let’s start by looking back at how smart I was last year… or how foolish.

Szymborski Bust Pitchers, 2022
Pitcher K/9 BB/9 HR/9 FIP ERA- ERA- Percentile WAR
Jack Flaherty 8.25 5.50 1.00 4.97 109 19th 0.0
Noah Syndergaard 6.35 2.07 0.94 3.83 98 32nd 2.2
Chris Flexen 플렉센 6.21 3.33 1.11 4.49 101 55th 0.7
Michael Pineda 5.01 1.54 2.51 6.13 151 5th -0.4
James Karinchak 14.31 4.85 0.46 2.29 53 70th 1.0
Emilio Pagán 12.00 3.71 1.71 4.21 116 28th -0.1
Mark Melancon 5.63 3.38 0.80 4.20 114 18th 0.1
Bryse Wilson 6.15 2.49 1.56 5.06 137 31st -0.1

All in all, this doesn’t look too bad. Karinchak was about at his typical levels, but the rest of the list didn’t generally provide much excitement. Syndergaard was the most valuable of the group, but hardly as the God of Thunder, and a league-average season was certainly a disappointment compared to what we remembered of him. Flaherty may have the been saddest bust on the list, as he was more or less a mess.

From the comments in the hitter articles, there’s still some lingering confusion on what I mean by a breakout or bust. When I pick a player to break out or bust, I’m basing this relative to the general expectations as I perceive them, not relative to the previous season’s performance. For example, Joey Gallo is a bust not because I think he’ll be worse than last season, but because I think he’ll be worse than those baked-in expectations; there has been a lot of speculation that the shift will save him, and I don’t think that’s true. You see this on the financial markets quite a bit, when the market reacts negatively to good news that’s not as good as what was already priced into the valuations, and vice-versa. Also remember that this isn’t necessarily me versus ZiPS; sometimes ZiPS agrees with me, and sometimes it angrily disagrees, or at least it would if I didn’t have the power to delete it from existence.

Without further ado, let’s get to the picks, and may the baseball fates have mercy on my soul. As this piece was completed over the first few days of the season, all eight players were finalized before the season started. A few of these players did have awful 2023 debuts, but that’s just “luck” on my part.

Sandy Alcantara, Miami Marlins

Alcantara is still likely to be one of the better pitchers in the league, and ZiPS certainly likes him, placing him among the leaders in WAR. But ZiPS is explicitly not trying to take into account rule changes, and I think Alcantara is one of the pitchers with the most significant chances to be affected by them. That’s a common theme among several of my bust picks this year, simply because this year, it’s something that causes additional uncertainty.

In this case, Alcantara, by far, had more groundballs hit into shifts than any pitcher in baseball in 2022, with 166; only seven other pitchers were above 100. I still think he’ll be a really good pitcher, but I expect his platoon splits will rise farther than ZiPS does, and before remaining confident he’s in ultra-elite territory, I want to make sure that the changeups that lefties facing Alcantara drive into the ground aren’t sneaking through at high rates.

ZiPS Projection Percentiles – Sandy Alcantara
Percentile ERA+ ERA WAR
95% 173 2.36 7.0
90% 156 2.62 6.5
80% 143 2.85 5.7
70% 135 3.02 5.2

Robbie Ray, Seattle Mariners

I’m a bit worried about Ray’s strikeout rate. While the dip from 2021 to ’22 wasn’t a big one, his peripherals in this department took a giant splat last year, with his swinging-strike rate falling off by 30%. His contact rate was his worst as an established major leaguer, and his called-strike performance also dropped considerably. ZiPS thought his peripherals, which are a leading indicator of strikeout performance, suggested a whopping 37 fewer strikeouts than were actually reflected in the record. And this isn’t a case of ZiPS having a pattern of underrating Ray’s strikeouts; zSO predicted 1,149 strikeouts for him in 2016–21 versus his 1,152 actual strikeouts. The dropoff in first-strike percentage also tends to mean an increase in walks, though Ray should at least be better than his first start this year!

At least, that is, when he returns from his current flexor strain. If that turns out to be more serious than it looks right now, we’ll have to call this an incomplete; it would be manifestly unfair for me to claim victory in a small sample size.

Corey Kluber, Boston Red Sox

ZiPS already isn’t too bullish on Kluber, so I’m in agreement with the computer in this case. I think what we have here is a perfect storm of risky indicators. He was solid in 2022 but also in a beneficial environment, with the Rays’ defense and the Trop being a good fit for him. He was never a flamethrower, but his limited velocity is getting even worse; he’s lost two mph from 2021, placing him at risk of “going Jered Weaver.” What’s more is that in a year in which there are additional incentives for putting balls in play — already less than ideal for Kluber — Fenway is the best non-Coors park for BABIP, and the Red Sox don’t have a particularly good defense. I think Kluber can still have success as the saavy, groundball veteran in a Chelcie Ross/Eddie Harris sense, but it’s more likely when he has the right support behind him.

Johnny Cueto, Miami Marlins

While Cueto has never been a pitcher who has relied on high strikeout rates, dipping under six last year was quite worrisome, both in its absolute number and the dropoff from the year before with the Giants. A large part of his success was one of his best seasons for home run rate allowed — especially impressive in Guaranteed Rate Field — but ZiPS thought that even his good exit velocity numbers last year should have yielded an additional seven homers. The fact that Cueto is the second Marlin on this list reflects one of the reasons I’m uneasy about the Pablo López trade: I think the Marlins would have been a lot better off had they tried to meet their offensive needs with money instead of lopping off some of their pitcher surplus. If Cueto struggles (and in his first start on Monday, he did, and also had to leave the game with a trainer), that pitcher surplus becomes more and more iffy.

Craig Kimbrel, Philadelphia Phillies

Kimbrel’s occasional implosions are a lot easier to stomach if he’s striking out 15 batters a game. He wasn’t in 2022, with easily the worst strikeout rate of his career, and that’s with the Dodgers, who seem to have a shocking ability to wring good performance out of practically anyone. Once one of the hardest pitchers in baseball to make contact again, he’s gradually degraded towards league average in this number, which isn’t exactly a formula in which he’ll find success given his penchant for occasionally getting hit very hard. While I wouldn’t overreact to his first appearance with the Phillies, I think he’s a very ordinary reliever who is getting by more on reputation than performance.

Mike Clevinger, Chicago White Sox

Clevinger got two starts in the playoffs last year, but his stint with the Padres has to go down as a major disappointment, one somewhat camouflaged by the decline in offense and being in a pitchers’ park. Losing a couple miles on his fastball may not have been fatal in itself, but it was hit quite hard last year, and none of his pitches were able to put away batters effectively on two strikes. I think he’s more of a reclamation project than a bounceback solution, and I don’t think an allegedly competitive team in a home run friendly park is necessarily the best place for that to happen.

Chris Bassitt, Toronto Blue Jays

ZiPS isn’t worried about Bassitt, at least in the short term (it has him dropping off fairly quickly in future seasons). But what ZiPS doesn’t know is that his velocity took a big dip in the spring. Last year, he was regularly in the 93–94 mph range with the occasional pitch at 95 or 96; in Florida, it was 90–92. It’s not unusual for a pitcher to dial it back a bit before the season starts, but he wasn’t just applying the brakes more often; all his fastballs were off. Bassitt’s fastest pitch this spring was 93.5 mph, below his average in more than half of his starts last year. If he were averaging 90–92 but still hitting 95–96, I’d be less worried, but I’m skeptical that he simply chose to go through a whole month without ever throwing his fastest fastball. Velocity drops tend to be red flags, so I think there’s additional risk here.

Kyle Freeland, Colorado Rockies

ZiPS thought that Freeland should have allowed 12 more homers in 2022 than he actually did, a pretty hefty number. To put this into context, zHR has been part of ZiPS since 2015, and over that period, only Madison Bumgarner in 2018 has “underperformed” by at least 10 homers (10.7). This isn’t a case in which Freeland has a history of beating his peripherals here either; zHR has never missed on him by more than two homers over a season. Add in the decline in his velocity, more flyballs than ever, and a park that’s still somewhat of a pinball machine post-humidor, and I think Freeland is a very risky pitcher.
