Amazingly, in an Opening Day game where Shohei Ohtani struck out double-digit batters in six shutout innings, the most memorable highlight of the night didn’t come from him, or even Mike Trout. In the bottom of the fifth, Oakland third baseman Jace Peterson sent a fly ball to right field. Hunter Renfroe gave chase, but it appeared to be going over his head — until he leapt up, stuck out his glove to the left while facing right, and somehow made an incredible no-look catch to the delight of Ohtani and the Angels. Even Peterson had to smile.

WHAT A CATCH BY HUNTER RENFROE ?

Baseball Savant has recently released outfield catch probabilities for individual plays, and we can learn a lot from analyzing the differences between the perceived difficulty of a play from watching it on a broadcast compared to its actual catch probability. Renfroe’s circus catch in Oakland offers a perfect example: While his acrobatics were necessary to make the catch, that was only because of a poor jump. He backpedaled for the first few steps, then ran at less-than-full speed while having to crane his head around to keep track of the ball. Renfroe ended up making the catch 39 feet from his initial position in an opportunity time of 4.2 seconds — a play that has a catch probability of 99%, and that’s even when accounting for the difficulty of running backwards (which is included in calculating the odds).

For comparison, here’s a play with a near-identical distance and opportunity time made by Renfroe’s backup, Brett Phillips.

Phillips didn’t need luck or heroics to make the out here; in fact, he was able to camp out for a bit before the ball fell into his glove. A good chunk of his route was completed before the broadcast had switched to the outfield camera.

In other words, Renfroe’s play is made with little fanfare almost every time. That includes him: He was perfect on fly balls with 99% catch probability in 2022, though he did let a few in the 90–95% range drop for hits. Much of the focus that observers put on the quality of a outfielder’s defense naturally comes from what can be seen on TV – but the data indicates that what we can’t see is what truly separates the great fielders from the poor ones.

Below is an analysis of the prospects in the farm system of the Philadelphia Phillies. Scouting reports were compiled with information provided by industry sources as well as my 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 I 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.

The Blue Jays were our staff pick to win the AL East, moreso due to the strength of their lineup than their pitching, though I think it’s safe to say that nobody thought their run prevention would be this bad, this early. Indeed, the team gave up nine runs to the Cardinals in an Opening Day victory, then lost three straight, surrendering nine runs in two of those games. Whether in Canada or the United States, that’s not a good exchange rate.

It’s not often that a team gives up nine or more runs in three of its first four games, and as you might guess, it’s rarely an indicator of quality. It’s happened just 12 times in the Wild Card era (1995 onward), including twice this year:

The 10 previous teams to get beat up with such frequency to start the season combined for a winning percentage that equates to a 71–91 record. Five of those teams went on to lose 95 or more games, and only two finished at .500 or better, with the 2001 Cardinals the only ones to make the playoffs, and that as a Wild Card team.

That’s not great company to be in, and yet the Blue Jays aren’t alone even among teams in their division; the Orioles gave up exactly nine runs in each of their first three games, making them the fourth Wild Card-era team to allow at least nine in all three and the first since the 2005 Rockies. Yet neither of them came close to allowing as many runs as the Phillies did over their first four games: 37, as compared to Toronto’s 31 and Baltimore’s 27. The reigning NL champions entered Tuesday night with a staff ERA of 9.28 as the team went 0–4; at least the Blue Jays won one game and the Orioles two. Funny enough, the three teams combined to allow four runs in their victories as I was writing this, as if you needed a reminder that such ugliness was unsustainable.

Admittedly, it wasn’t pretty for the Blue Jays’ starters in those four games, as they were rocked for a 10.80 ERA and 6.49 FIP in 18.1 innings. While one turn through the front four of the rotation is just that — a mere 2.5% of the season — the lack of surrounding data feeds into anxieties about what could go wrong. As a matter of due diligence for those who might consider riding the Blue Jays’ bandwagon as well as those who are already hyperventilating, let’s take a closer look.

Alek Manoah had the honor of the Opening Day start after a season in which he made his first All-Star team and finished third in ERA (2.24) as well as the Cy Young voting. Facing the Cardinals, he was staked to a 3–0 first-inning lead but quickly gave back a run via an infield single, an error, a walk, and a single by Nolan Arenado in a laborious 29-pitch frame. After a scoreless second, he served up a two-run homer to Tyler O’Neill in the third, then gave up a two-run homer to Brendan Donovan in the fourth before getting the hook with two outs. Final line: 3.2 innings, nine hits, five runs, two walks, three strikeouts.

Obviously that’s not what you want, but his performance didn’t offer any major red flags. Manoah’s fastball velocity was slightly up from last year (94.1 mph versus 93.8), and while the results on his slider weren’t good (the Cardinals went 4-for-5 with a homer), its velocity and movement were in line with last year (it scored a 117 in Stuff+). Manoah said afterwards he wasn’t aggressive enough. “One thing I’ve got to remember is I’m really good myself,” he told reporters. “Sometimes you might go in there and face a good lineup and the act of giving them a lot of credit makes them even better.”

The Blue Jays did come back to win that one despite Manoah’s struggles. On Saturday, however, they squandered a good effort by Kevin Gausman (six innings, three unearned runs, one walk, seven strikeouts), as starter Jack Flaherty and relievers Drew VerHagen and Andre Pallante kept them hitless through 6.1 frames (albeit with seven walks from Flaherty) before Kevin Kiermaier singled. The unearned runs came with two outs and two on in the third inning, when Matt Chapman’s bobble and throwing error on an Arenado grounder brought in one run and Nolan Gorman followed with a two-run single.

Gausman’s average four-seam velocity was down 1.1 mph relative to last year (93.9 versus 95.0) but off by only 0.5 mph relative to his monthly averages for April and May of that season; he averaged 93.6 mph in his first outing of 2022. Again, probably nothing to worry about.

Far more troubling were the performances of Chris Bassitt on Sunday and José Berríos on Monday. Signed to a three-year, $63 million deal in December, Bassitt had a brutal debut, serving up four homers and allowing nine runs in 3.1 innings. His first official pitch as a Blue Jay, a high changeup to Donovan, ended up going over the right centerfield wall for a 397-foot solo homer. Two pitches later, Alec Burleson hit a high fastball 363 feet over the left field wall. With two outs and one on later in the frame, Gorman destroyed a hanging curveball, sending it to right-center for a projected distance of 446 feet. He hit another two-run homer, 395 feet to right-center off a cutter in the middle of the zone, in the third inning.

By the time manager John Schneider came out to get Bassitt in the fourth, he had secured the worst outing of his career in terms of hits (10), runs, homers, and Game Score v2 (-8). He didn’t walk or strike out a single hitter and induced just four swings and misses and six called strikes from among his 57 pitches, for a CSW% of 17.5%.

As Dan Szymborski noted in his 2023 Bust Candidates rundown, the 34-year-old righty’s velocity was down all spring. “Bassitt’s fastest pitch this spring was 93.5 mph, below his average in more than half of his starts last year,” he wrote. “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.”

That trend continued on Sunday, with the velocity on Bassitt’s sinker (his primary fastball) off 1.7 mph relative to last year (91.1 mph versus 92.8), and most of his other pitches were similarly off as well; he reached 93 mph just twice. Afterward, Bassitt found himself “at a loss for words a little bit” because he’d “never had a game” where so many types of pitches from his broad arsenal (he threw eight different pitch types according to Statcast) were hit so hard. Twelve of his 19 batted ball events reached or exceeded 95 mph; among pitchers with at least 10 batted ball events this season, only Chris Sale had a higher hard-hit rate than Bassitt’s 63.2% (Germán Márquez tied him).

“I think it was just mis-executed pitches,” Schneider said. “He just didn’t really hit his spots. A team like that, you can’t make mistakes. I know he focused on the middle of their order, and it was the guys before and after those guys who did damage. I think it just came down to poor execution.”

Absent any reports of injury or discomfort, this should be something Bassitt and the Jays can fix. But if his underperformance ends up being an aberration, Berríos’ struggles against the Royals on Monday had a more familiar ring. He gave up four hits and three runs in the first inning, settled down for a couple of frames, then was tagged for five more hits — four of them with exit velocities of 98.3 mph or higher — in a four-run fourth. He also walked one batter, who scored when MJ Melendez greeted reliever Zach Pop with a sixth-inning homer. The eight runs allowed matched last year’s high and marked the seventh time in his last 28 starts in which he allowed six or more runs.

Berríos’ 93.9-mph average four-seamer velocity was just 0.1 mph off last year, and he did strike out seven with 11 swings and misses (seven on his slurve) and a 30.3% CSW%; his 33.3% chase rate matched his career average. But when he was hit, he was hit hard, with an average exit velo of 94.1 mph and a hard-hit rate of 61.1%. His performance wasn’t as extreme last year — we are talking about one start compared to 32 — but those contact stats were dreadful. His 9.5% barrel rate placed in the 15th percentile, which was at least higher than his 90.0 mph average exit velo (13th), 43.8% hard-hit rate (11th), or 5.11 xERA (ninth); meanwhile, his 5.23 ERA was the highest of the majors’ 45 qualifiers, and his 4.55 FIP was the AL’s second highest. In the context of his being in the first year of a seven-year, $131 million extension, the performance was an unsettling one, to say the least.

Last August, Ben Clemens noted that where Berríos had previously gotten away with leaving a lot of four-seamers in the middle of the strike zone, last year those were getting demolished. More recently, old friend Travis Sawchik added that Berríos threw a career-low 7.1% of fastballs (four-seamers and sinkers) on the edges of the plate against lefties. More:

Berríos allowed a career-worst batting average of .447 to lefties on fastballs in the “heart” of the strike zone, according to MLB’s Statcast data – which was more than .100 worse than his next worst season.

He allowed 29 home runs last year, sixth most in the majors, and left-handed hitters crushed 20 of them; 12 came via Berrios’ fastball. Only Josiah Gray of the Nationals allowed more home runs to lefties.

On the whole, the Statcast value of 17 runs above average on Berríos’ four-seamer made it the majors’ sixth-least valuable heater and the eighth-least valuable pitch of any stripe. Repeating a table from my Madison Bumgarner piece:

While Berrios did throw 9% of his fastballs on the edges of the zone against lefties on Monday, 14.6% of such pitches wound up in the heart of the zone, nearly double last year’s rate of 7.7%. Three of the hits he allowed, including a Nicky Lopez triple, came on such pitches, and the six batted balls those pitches produced averaged 102.2 mph with a .957 xSLG. His 13 pitches in that location to lefties had a .559 wOBA, even higher than last year’s .511. All of which is to say that Berríos still has work to do, particularly against lefties.

Thankfully for the Blue Jays, on Tuesday night, Yusei Kikuchi stopped the bleeding with a five-inning, three-hit, one-run performance in a 4–1 victory over the Royals, with a 455-foot Franmil Reyes homer the only blemish. It was only one victory, and that against a team that lost 97 games in 2022, but the winning has to start somewhere.

If you compare our staff predictions for the season to our preseason Playoff Odds, for five of the six divisions our staff picks line up with the crunched numbers, with the Braves, Cardinals, Padres, and Astros all favored to win, and the Twins and Guardians a tossup. Only in the AL East did our staff go against the odds, picking the Blue Jays over the Yankees by a margin of 19–6 despite the latter’s 42.7%–29.4% edge.

I was one of those 19, my own pick influenced — perhaps overly so — by the mounting casualties within the Yankees’ rotation. First it was Nestor Cortes‘ hamstring and Frankie Montas‘ shoulder, then Carlos Rodón‘s forearm and Luis Severino’s latisimuss dorsi. Of those, Cortes’ injury was minor enough that he still took his first regular-season turn on schedule, and only that of Montas — a shoulder issue that required arthroscopic surgery that could keep him out until late in the season — is serious. Even so, it’s not hard to look at the track records of Rodón and Severino and imagine much longer outages than initially projected.

The Jays’ rotation, though it ranked “only” 11th in our preseason Positional Power Rankings (where the Yankees were first even with their injuries) entered the year seemingly healthy, with the projections for Manoah (2.9 WAR) and Gausman (3.7) feeling a bit light compared to what they’d shown last year (4.1 WAR and 5.7, respectively), suggesting some possible upside. Combine that with a stronger lineup that carried fewer question marks — only at second base did the Blue Jays rank below 11th among the non-pitchers, where the Yankees had three such spots — and you can understand why Toronto was a trendy pick.

The Blue Jays may indeed come out on top, but at the very least, their starters will have to pitch up to their capabilities if that’s to happen. As the first week of their season has shown, it’s not all going to happen simply based on hype.

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 »

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 »

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 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 »

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:

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.

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.

Once upon a time, a Clayton Kershaw–Madison 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:

Looks like the D-backs were tipping pitches last night against the Dodgers. Some pictures: Kevin Ginkel slider (wrist curl, grass between arms), Kevin Ginkel fastball (no wrist curls, no grass) and Madison Bumgarner letting runner on second see right into his glove. pic.twitter.com/rd2H8C1TAL

— Eno Sarris (@enosarris) April 2, 2023

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:

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:

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.
