There comes a time in many a Red Sox pitching prospect’s life when he is likened to Pedro Martinez, which must be every bit as intimidating as it is flattering. His name was invoked when the Red Sox acquired six-foot-flat Dominican fireballer Rubby de la Rosa — whose grandmother nannied the Martinez boys back in Santo Domingo — in the blockbuster 2012 deal that sent Adrian Gonzalez, Carl Crawford, Josh Beckett, and Nick Punto to the Dodgers. Martinez was again floated as a lofty comp for small-framed Venezuelan right-hander Anderson Espinoza when he emerged as the team’s most promising pitching prospect in 2015 and ’16. Across the league, countless others have drawn the hopeful comparison, sometimes of the Hall of Famer’s own accord.

For 24-year-old Red Sox starter Brayan Bello, the comparisons started at least a couple of years ago. The diminutive Dominican right-hander was also overlooked for his smaller frame in his youth, and while he favors a two-seam fastball over his four-seamer — both register in the mid-90s velocity-wise — it’s the changeup that is perhaps most reminiscent of the pitcher he calls an idol. In May 2021, Peter Gammons quoted a team official noting that Bello was “up to 97 with the best changeup I ever seen, at least since Pedro.” For Bello, the comparison hasn’t exactly been unwelcome; in May of last year, upon his promotion to Triple-A, he said through a translator that he ”would eventually like to be better than him,” reflecting a kind of unabashed confidence that itself is not unlike the former Sox ace.

When Carlos Rodón returns to the mound tonight — the 30-year-old New York Yankees southpaw has been out all season with forearm and back issues — he’ll be doing so with one of baseball’s best-known sliders. Long his signature pitch, it has contributed heavily to his success, which includes a 2.67 ERA, a 2.42 FIP, and a 12.23 K/9 rate between the 2021 and ’22 campaigns. As far back as 2016, former FanGraphs columnist (and now Tampa Bay Rays analyst) Jeff Sullivan compared Rodón’s slider to the one thrown by future Hall of Famer Clayton Kershaw.

Harkening back to my Learning and Developing a Pitch series, which has been on hiatus since last July, I recently asked Rodón for the story behind his slider.

———

Carlos Rodón: “The slider I throw now is the same one I threw in college. Before I got to [North Carolina State University], it was more of a slurve. My pitching coach in college was Tom Holliday, and he thought that I should throw a harder breaking ball as opposed to one that was more curvish/slurvish. He said, ‘Let’s try to make this closer to a true slider,’ showed me a grip, then said, ‘I want you to throw this as hard as you can.’ I did, and from there it didn’t take very long to develop into the breaking ball I have now. It fell into my arsenal pretty easily.

“The grip isn’t a traditional slider grip. The tracks of the ball, above the horseshoe — both horseshoes — like you’re throwing a two-seamer… you spin it like you’re going straight perpendicular across [the seams]. You’re crossing them, and then my leverage is on that next horseshoe. The leverage is with my middle finger, and while that’s traditional, the grip itself is kind of unorthodox. It’s not like I’m on just one seam. It’s hard to explain, but I’m kind of above it. Read the rest of this entry »

No one can deny that baseball’s new rules are having the intended effects. BAPIP is up, game times are down, and stolen bases are back. Attendance is growing too, and while we can’t give the rule changes all the credit for that one, they’ve certainly done their part. Even better, the new rules aren’t leading to the adverse side effects some of us feared. The pitch clock isn’t causing widespread injury, pitch timer violations have been steadily decreasing as players adapt, and bigger bases haven’t led to any reports of Ty Cobb rolling over in his grave.

As efficacious as all the new rules have been, one stands above the rest. In my humble opinion, the disengagement limit has proven to be the gold standard of rule changes. Let me explain.

I like the pitch clock. Imaginary audience applauds. I like the shift restrictions. Imaginary audience begins to turn on me. I even like the automatic runner on second in extra innings. Imaginary audience starts throwing rotten fruit. But as much as I appreciate those new rules, I understand they all came at the expense of something else, something fans once cherished. The pitch timer offends purists who believe baseball shouldn’t have a clock. The shift restrictions limit smart defensive positioning in service of hitters who can’t adjust. The automatic runner warps each team’s priorities in the 10th inning onward. But the disengagement limit? It’s been a roaring success, and it hasn’t cost us anything at all.

Late-career resurgences from former stars are fascinating to me. This is a terribly difficult game even when you are at your peak strength and athleticism; as your body declines, it only gets more difficult. Some are just unable to adjust to new circumstances, including former stars. But every now and then, you have a hitter who can make the right tweaks to adapt to their new body and changed environment. There are only a handful who do that every year; this season, Evan Longoria is one of them.

After an injury-laden 2022, the future was murky for Longoria. Last year, he went on the IL for hand surgery, an oblique strain, and a hamstring strain, and ultimately missed the last week of the season after taking a 100-mph line drive off the thumb, leading to a fracture. He had no intentions of retiring before or after the fracture, though; it was only a bump in the road that his potential new team would have to consider, since the Giants did not exercise his club option. He ended up signing a one-year, $4 million dollar deal with the Diamondbacks, where he has enjoyed his best offensive season since 2016 by wRC+ and xwOBA. It comes in a limited sample and strategic playing time from Torey Lovullo, but it’s far from a fluke. Longoria is impacting the ball as well as he ever has in the Statcast era. Here is a table detailing his jump in performance and quality of contact relative to recent seasons:

Every single one of these metrics is a personal high for Longoria since 2015, and some by a wide margin, which is pretty remarkable for a player coming off so many injuries in the back half of their 30s. His HardHit% is fifth in the league among hitters with at least 50 batted balls, putting him in between Juan Soto and Vladimir Guerrero Jr. on that list. Pair that with great consistency in hitting the ball between eight and 32 degrees, and you have yourself an xwOBACON over .500 — also good for fifth in all of baseball among hitters with at least 100 plate appearances.

The Joey Bart Era, such as it was, may already have ended in San Francisco. Struggling to fill the shoes of Buster Posey — admittedly, a ridiculously tall task for anyone — the 26-year-old backstop strained his groin in mid-May; by the time he was healthy enough to return, the Giants had shifted their focus to a younger catcher they were even happier with in Patrick Bailey. After finishing last season in High-A, the 24-year-old Bailey rocketed through the minors this spring, and upon arrival has hit and fielded well enough to help turn the Giants’ season around.

Recall that Posey retired abruptly after the 2021 season, at age 34. The move shocked the entire baseball world, not just the Giants, who had just won 107 games and planned to discuss retaining him upon the expiration of his nine-year, $169 million contract, whether by picking up his $22 million option or by hammering out a longer-term deal. Yet Posey, who had opted out of the 2020 season in order to spend time with his family, which had expanded to include two adopted twin daughters who had been born prematurely, felt the pull of home. Having checked every box for a Hall of Fame resumé except the padded career totals, the sad decline, and the long goodbye, he hung up his mask.

The Giants pivoted to Bart, who had looked like the heir apparent when he was taken with the second pick of the 2018 draft out of Georgia Tech. In Posey’s absence, he had done the bulk of the work behind the plate in the pandemic-shortened 2020 season, but his inexperience showed, and he spent most of ’21 in the minors. While he began the 2022 campaign with promise by homering off Sandy Alcantara on Opening Day, he was optioned to Triple-A Sacramento in early June. Though he played somewhat better upon returning a month later, he finished with just a .215/.296/.364 (90 wRC+) line and an astronomical 38.5% strikeout rate in 297 PA, with -3.7 framing runs and a meager 0.6 WAR.

After making a two-inning cameo on Opening Day of this season, Bart landed on the injured list due to a mid-back strain. He additionally missed time in late April due to right groin tightness, then was diagnosed with a Grade 1 left groin strain in mid-May. In between all of the injuries, he hit just .231/.286/.295 (63 wRC+) in 84 PA; while he trimmed his strikeout rate to 25%, he walked just twice (2.4%). He started 22 of the team’s 43 games before landing on the IL a second time, with Roberto Pérez making five starts before suffering a season-ending rotator cuff tear and rookie Blake Sabol starting 16 games.

Enter the 6-foot-1, 210-pound Bailey, who was chosen with the 13th pick of the 2020 draft out of North Carolina State. He entered last season at no. 76 on our Top 100 list as a 50 FV prospect but was downgraded due to his early-season struggles at High-A Eugene, where he had finished the 2021 season. While he finished with a respectable .225/.342/.420 (113 wRC+) line with 12 homers, he missed the Top 100 — not just ours, but every major top prospect list of note throughout the industry. Baseball America, for example, ranked him 27th among Giants prospects, calling him a plus defender with “sound footwork and quick release” but also “a switch-hitter with an inconsistent approach [who] gets in trouble when he starts chasing power.” The publication saw his ceiling as that of “a defense-minded backup catcher.”

It wasn’t until last week that Eric Longenhagen and Tess Taruskin published the Giants’ Top 49 Prospects list here. Ranking Bailey third behind Luis Matos and Kyle Harrison, they began the entry with a mea culpa: “Time to eat double crow here, as Bailey was just outside the Top 100 when he was drafted and throughout 2021 before we rounded his FV grade down during an uneven 2022. When we put together the lengthy Giants Imminent Big Leaguers piece, Bailey was not included, as we didn’t anticipate he’d spend just two weeks each at Richmond and Sacramento before the club decided to insert him as their primary big league catcher.”

Indeed, Bailey moved quickly this spring, hitting .333/.400/.481 (143 wRC+) with two homers in 60 PA in Double-A and .216/.317/.353 (61 wRC+) in 60 PA at Triple-A. He got the call when Bart hit the IL, debuted with a late-inning cameo on May 19, and went 1-for-3 in his first start the next day, singling off the Marlins’ Tanner Scott. The day after that, he clubbed a solo homer off Jesús Luzardo and added another RBI later in a 7–5 win. A week after his debut, on May 26, he went 4-for-5 with three RBI in a 15–1 rout of the Brewers; three days later, he went 3-for-5 with a double, a homer, and four RBI in a 14–4 shellacking of the Pirates.

The hits keep coming, and the Giants keep winning. Bailey is batting .302/.336/.512 for a 128 wRC+ — second on the team behind LaMonte Wade Jr.’s 139 — with five homers in 139 PA. The Giants, who were 20–23 before he was called up, are 27–17 since; they won nine straight from June 11 to 21 and soon after pulled to within 1.5 games of the NL West lead. They’ve since fallen back to third place in the division behind the Diamondbacks (50–37) and Dodgers (48–38) and are three games out at this writing, though they’re in a virtual tie with the Phillies (46–39) for the third NL Wild Card spot.

The one win during the team’s recent 1–6 skid was something of a Bailey showcase. Last Friday (June 30), in the eighth inning of the opener of a three-game series against the Mets at Citi Field, he hit a 432-foot three-run homer to center field off David Robertson, turning a 4–2 deficit into a 5–4 lead. With heat-throwing closer Camilo Doval issuing a one-out walk in the ninth, Bailey then made a perfect throw to nab pinch-runner Starling Marte attempting to steal, thus ending the Mets’ franchise-record streak of 35 straight stolen base attempts. On the next pitch, Doval struck out Brandon Nimmo to preserve the win.

“That was as good as it gets,” manager Gabe Kapler said afterwards. “That was superstar-caliber stuff.”

Getting back to our prospect team’s evaluation of Bailey: while putting a 40 present and 50 future grade on his overall defense and a 45 grade on his throwing, they noted, “He is a skilled one-knee’d receiver, great at beating the pitch to the spot in all parts of the zone, often subtly shifting his body to help him receive borderline pitches with strike-stealing stillness.” The numbers back this up; by FanGraphs’ measure, Bailey is 4.8 runs above average in framing in just 302 innings behind the plate, and by Statcast’s measure, he’s four runs above average. He’s done a great job against the running game, with pop times to second base averaging 1.87 seconds. He’s thrown out 12 out of 31 stolen base attempts for a 39% success rate, nearly double the league average of 20%; Statcast rates him as two runs above average in that department, but one run below average in blocking.

On the offensive side, while Bailey hit well from both sides of the plate in college, he struggled mightily against lefthanders in the minors, albeit in a comparatively small sample, an average of less than 50 PA per year. “A natural righty, he viewed the splits as being in part because of a lack of opportunity — he had just 61 at-bats against lefties last year — and made adjustments this spring to his swing and approach,” wrote NBC Sports’ Alex Pavlovic. “The Giants sent Bailey off to Double-A with a plan to spend more time on his right-handed swing during batting practice since he won’t get as many opportunities in games.”

The practice seems to be paying off, because Bailey has not only been effective against lefties within a very small sample, but he’s also put up insane numbers thanks to a BABIP that’s nearly double what it was in the minors — and quite unsustainable. Those have propped up a righty performance that’s slightly above the league average for a catcher (86 wRC+) but hardly exceptional, with strikeout and walk rates that rate as concerns.

Contact-wise, Bailey’s got enough total batted ball events that he’s past the point where the numbers start to stabilize. While the individual platoon splits haven’t entirely reached that point, his actual numbers from both sides are close to his expected numbers — and quite robust:

Bailey really is hitting the ball much harder from the right side of the plate, not that anyone should expect him to maintain Rogers Hornsby’s 1924 numbers.

Getting back to the walk and strikeout stuff: Bailey’s rates are out of balance, but it’s not as though his 44.7% swing rate, 29.1% chase rate, or 9.9% swinging-strike rate stand out as egregious or as marks that can’t be attached to reasonable production. Consider, for example, this list of players who are within 0.2 percentage points of his overall swing rate, two points of his chase rate, and one point of his swinging-strike rate:

Those are largely productive hitters, and the biggest difference seems to be that they’re taking fewer called strikes than Bailey en route to more balanced walk and strikeout rates. But again, it’s not like he is extraordinarily passive or aggressive. Note his -1 run rating in the Statcast shadow zone; he’s taking slightly more pitches in that zone than the league average (52% to 47%) and slightly more than average in the heart of the zone (31% to 28%) as well:

Anyway, for now as he’s making his way around the majors for the first six weeks of his career, Bailey has been exceptionally productive. I would caution that while he appears to have taken a significant leap forward from his minor league stats and pre-2023 scouting profile, the Posey comparisons he’s drawn — comparisons to a franchise pillar and future Hall of Famer (seriously, fight me) who began his career by winning NL Rookie of the Year honors in 2010 — are over the top. “Hey, let’s pump the brakes a little bit,” said Kapler in response to that line of discussion prior to Bailey’s big game in New York. “It’s a month into his career. Let’s let things unfold.”

As for what this means for Bart, he hasn’t exactly been Pipped out of a job given his struggles, but it’s tough to see him getting it back. For the near future, he may be blocked by Sabol, a Rule 5 pick from the Pirates who’s hitting .251/.313/.438 (104 wRC+) and putting up decent defensive numbers while splitting time between catching (26 starts and a total of 228 innings) and left field (183.2 innings). With his versatility, the Giants could carry three catchers, but doing so only to have Bart sit on the bench instead of working to improve at Sacramento probably isn’t in his best interest. For the longer term, he may be a change-of-scenery candidate — a player whose value is currently at the lower end of its range but one who was previously judged to have the makings of an everyday catcher, who has fewer than 500 PA under his belt, and who still has five years of club control remaining. If he doesn’t get another look in San Francisco, somebody out there will give him a shot.

As the Giants approach the August 1 trade deadline, it will be interesting to see if Bart’s name comes up as they shop to fill their needs. In the meantime, we should probably expect Bailey to cool off and should hope that folks cool it with the Posey comparisons; he casts a long enough shadow over the Giants’ organization as it is. Nonetheless, it’s exciting for any rookie to arrive, put his claim on a starting spot, and help turn his team’s fortunes. Let’s see where Bailey goes with this next.

Bryce Miller led off last Friday’s game with a fastball to Yandy Díaz. He missed low and away, and Diaz took the pitch for ball one. Miller came back with another fastball, wildly away, then another one low to send the count to 3–0. But then things turned. He threw another fastball right down the middle for strike one, fired one past Díaz for strike two, and finally threw a perfectly-located missile that Díaz waved through. Six pitches, six fastballs, and one out: it’s exactly how Miller drew it up at home.

The rest of the first inning held more of the same. He threw Wander Franco three straight fastballs to garner another strikeout, one that Luke Raley tapped into play (he reached on a fielding error), then six straight fastballs to Randy Arozarena to duplicate the 3–0-to-strikeout path he’d walked against Diaz. All told, Miller threw 16 fastballs in the first inning and nothing else whatsoever.

To some extent, this was an unsurprising tactic. Miller boasts one of the best fastballs in baseball, period. It’s one of those mindbending pitches that seems to defy gravity by rising out of its path halfway to home plate. Whether you’re looking at it statistically or visually, it’s hard to find faults. He’d used it nearly two-thirds of the time heading into last Friday’s game. Read the rest of this entry »

When my colleague Ben Clemens wrote about Eury Pérez a week ago Tuesday, he called him “amazing.” It’s an apt description. Over his first 10 big-league starts, the 6-foot-8 Miami Marlins right-hander is 5–2 with a 2.47 ERA, a 3.61 FIP, and 54 strikeouts in 47.1 innings. Moreover, if not for a clunker in his most recent outing — six runs allowed and just one out recorded against the powerhouse Atlanta Braves — his numbers would be even better. Less than three months after celebrating his 20th birthday, Pérez has already established himself as one the best young pitchers in the game. His bona fides preceded his mid-May debut; the precocious youngster came into this season ranked as our top pitching prospect (and No. 3 overall on our Top 100).

Pérez has matured exponentially, both physically and as a pitcher, since being signed by Miami out of the Dominican Republic in July 2019. Reportedly 170 pounds when he inked his first contract, he’s now listed at a sturdy 220. His fastball velocity has grown just as much, climbing as high as triple digits and averaging a firm 97.6 mph. He’s also honed his secondary offerings: a changeup, a curveball, and a slider.

I asked the über-talented Santo Domingo native about his development path when the Marlins visited Fenway Park last week. Read the rest of this entry »

The Dodgers came into 2023 with a ton of question marks. Was a platoon of James Outman and Trayce Thompson truly the answer in center field? Was Miguel Rojas a sufficient backstop given Gavin Lux’s injury? Was Jason Heyward’s bat salvageable, and where would he play if it was? Was Miguel Vargas ready? The offense was hardly up to the standards of the team’s recent run.

They didn’t answer all those questions positively, but with the benefit of hindsight, the offense seems fine. The team is hitting a collective .243/.328/.446, good for a 110 wRC+. They’re one of the best baserunning teams in baseball. Mookie Betts can play shortstop now, which is neat. But they’ve exchanged those worries for one that has dogged every team in baseball over the years: Is there enough starting pitching to go around?

In the past week, the Dodgers were dealt two more blows on that front. One is a bump in the road: Clayton Kershaw’s sore left shoulder sent him to the IL Monday, where he hopes to make a minimum 15-day stay. That’s mildly concerning, but if Kershaw and the Dodgers are right, it’s just a temporary setback. One of Kershaw’s potential replacements got far worse news, however. Yesterday, the club announced that Dustin May will have elbow surgery to repair his flexor tendon, which means he’s done pitching in 2023. Read the rest of this entry »

Mookie Betts ended June the way he began it, by leading off the Dodgers’ half of the first inning with a homer, then adding another later on as one of his three additional hits. He bookended his month by doing so against the Yankees in Los Angeles on June 2, then against the Royals in Kansas City on June 30. Along the way, he added an additional five homers, boosting his season total to 22 (he hit his 23rd on Tuesday night against the Pirates), and he’s remained hot as July has begun. Not surprisingly, he’ll be the National League’s starting lineup in next week’s All-Star Game.

Betts has been on a leadoff homer binge this season. Just past the midway point, he’s hit nine already, including five in June, and three in an eight-day span as the month ended:

Betts’ total to date ties him for ninth on the single-season leaderboard, though he’s just four homers shy of the record, which was challenged by Jose Altuve last year, when he fell one short:

You’ll note that all but one of those 13 seasons has taken place in the Wild Card era (1995 onward), and over half of them have occurred in what we might call the Statcast era (2015 onward). Those high concentrations have plenty to do with the higher home run rates of recent seasons, and they also owe plenty to teams’ increasing willingness to bat power hitters first. Who doesn’t find the possibility of a quick 1–0 lead tantalizing? Read the rest of this entry »

Jacob Berry saw his prospect stock drop earlier this season. Highly regarded coming in, the sixth overall pick in last year’s draft had an abysmal .477 OPS in April and his .509 mark in May was barely better. Showing little resemblance to the player who’d raked first at the University of Arizona and then LSU, he fanned 41 times while logging just 25 hits, only two of which left the yard. Playing at High-A Beloit in Midwest League spring weather certainly didn’t help, but red flags were nonetheless flying. When our Miami Marlins Top Prospects list was published on May 31, Eric Longenhagen wrote that he was “content to have a hair trigger when it comes to sliding Berry because I was already skeptical… but deciding how much to slide him is challenging.” Our lead prospect analyst ultimately settled on No. 11 and a 40+ FV for the switch-hitter.

Berry’s June was markedly better. Rebounding from his two-month swoon, the 22-year-old third baseman slashed a solid .287.358/.447, with 10 of his 27 hits going for extra bases. Only one of them cleared the fence — his surprising lack of pop remains a concern — but overall, his success at the plate was much more in line with expectations. Despite understandable concerns, he remains a viable big league prospect.

What’s been behind his improved performance? Berry declined a recent interview request to discuss any adjustments he might have made, but he did sit down to discuss his hitting approach late in spring training. Read the rest of this entry »
