In terms of rankings and projection, Mick Abel is much the same pitcher he was 24 months ago. When the now-22-year-old right-hander was featured in February 2022 during our annual Prospect Week, he was No. 1 in the Philadelphia Phillies system and No. 20 on our Top 100. Fast forward to the present, and he is No. 2 in the Philadelphia Phillies system and No. 22 on our Top 100. As Eric Longenhagen explained in his recent writeup, “Abel didn’t have an especially good 2023… [but] still has most all of the ingredients needed to be an impact starter, he just isn’t totally baked yet.”

How has the 2019 first-rounder out of Beaverton, Oregon’s Jesuit High School matured the most since our conversation two years ago? I asked him that question at Philadelphia’s spring training facility in Clearwater, Florida on Friday.

“I’d say it’s the separation of over-the-rubber and over-the-plate mentality, knowing how to distinguish between the two,” replied Abel, who had a 27.5% strikeout rate but also a 13.5% walk rate in 108-and-two-third innings with Double-A Reading last year. “Whether it’s in the bullpen or on the game-mound, knowing when and how to make adjustments without getting too deep in my head about it.

“Staying more direct and knowing that if I get too long with my arm action in back I’m going to be a little later to the plate,“ Abel said when asked to elaborate on the actual mechanics. “I want to make sure that everything is on time going down the hill.” Read the rest of this entry »

When Adam Jones compared his former Orix Buffaloes teammate Masataka Yoshida to Juan Soto, he quickly established the lofty expectations that Yoshida would face as he made the transition to the major leagues. The comparison painted a clear picture of the type of batter Yoshida was in Japan. For all of Soto’s success on contact, his truly elite skill is his plate discipline, and the same was true for Yoshida. In five of his seven seasons in Japan, he ran a walk rate higher than his strikeout rate while posting a 176 wRC+ during his career in his home country. In his final year in NPB, he had the second-lowest strikeout rate and second-highest walk rate among qualified batters.

The transition from Asian leagues to the majors has usually been more difficult for batters than for pitchers. High velocity is the greatest concern, but the quality of breaking and offspeed offerings is much higher as well. For Yoshida, his pitch recognition skills seemed like they’d help him overcome these common problems, even if his overall plate discipline suffered a bit. While he wasn’t able to reach the heights of his career in Japan, he did manage to record a 109 wRC+ in his first big league season, though his 0.6 WAR was certainly lower than the Red Sox were expecting when they signed him to a huge five-year deal. His overall value was hurt by some ugly defense in left field; then again, his glove was never his strength. More concerning was that his approach at the plate worsened as the season went on, leading to a dreadful final two months that greatly diminished what otherwise would have been a successful rookie year.

Through the first three months of the season, everything looked like it was working out; he was posting a 129 wRC+ with 8.7% walk rate and an 11.3% strikeout rate. The plate discipline looked like it had made the transition without any fuss, and he was hitting for some power to top it all off. Unfortunately, over the next three months, things took a turn for the worse, dragging his overall line down to where it ended the season. It’s pretty easy to see what the issue was when you look at his rolling strikeout and walk rates during the season.

From July 1 through the end of the season, he took just seven walks total and his strikeout rate jumped to 17.0%. He continued to produce in July, even as he began to lose his plate discipline, but everything crumbled over the final two months, when he slashed .257/.276/.371 and had a 68 wRC+ across 181 plate appearances.

So what happened to his legendary plate discipline skills that drew comparisons to those of Soto during the second half of the season? Looking under the hood, it seems like he started pressing once he started struggling. When you compare his underlying plate discipline metrics from his time in Japan to his rookie season, you can pretty clearly see where things went wrong.

In Japan, Yoshida’s low swing rates were the backbone of his approach. The qualified batter with the lowest swing rate in the majors last year was Yoshida’s World Baseball Classic teammate Lars Nootbaar (35.3%), followed by Soto (35.7%). At his peak in Japan, Yoshida approached that level of selectivity. This, combined with a low chase rate and high contact percentages on pitches in and out of the zone, was Yoshida’s recipe for success.

During the first half of last season when his plate discipline was still intact, his swing and chase rates looked similar to what he had been running in Japan. Everything trended the wrong way during the second half of the season; he became much more aggressive and started chasing pitches out of the zone at a far higher rate than he had in years.

It’s worth noting that fatigue certainly contributed to Yoshida’s struggles. The schedule in the majors is far more grueling than it is in NPB, where all the games are played in the same time zone and the longest flight takes about 3 1/2 hours. Yoshida was gassed by the end of June, right around the time he lost his approach.

When we’re analyzing a hitter’s plate discipline, looking at swing, chase, and contact rates are usually the most commonly cited metrics because they’re publicly available, but they’re a pretty blunt tool when trying to discern a hitter’s swing decisions. Thankfully, Robert Orr of Baseball Prospectus has done some fantastic work to illuminate this problem. Back in November, he introduced his SEAGER metric, which looks at expected swing or take run values and grades a player’s swing decisions based on what they actually did. It has two components: the rate of hittable pitches taken, which measures aggression; and the rate of bad pitches taken, which measures selectivity.

As you’d expect from the name of the metric, Corey Seager’s swing decisions grade out incredibly well. Juan Soto also does well via this methodology, sitting ninth in baseball in SEAGER and first in selectivity. Based on his reputation and his swing, chase, and contact rates in Japan, you’d expect Yoshida to have a high-selectivity, low-aggression SEAGER profile. That’s not exactly what the data bears out.

Yoshida’s SEAGER was quite poor because he wasn’t aggressive enough on hittable pitches to compensate for his lower-than-expected selectivity, which was roughly league average. For comparison’s sake, I included Soto’s SEAGER metrics above just to marvel at how incredible his ability to lay off bad pitches is.

When we look at the rolling graphs of Yoshida’s SEAGER components, we get a much clearer picture of what happened during his season. First his selection tendency:

We can see that Yoshida was extremely selective early in the season, up near the Soto range, but that cratered as the season went on and only barely recovered by the end of the year. His discerning eye at the plate was supposed to be the elite skill that would help him make the transition to the major leagues. That was the case for the first few months before he lost his way.

His rolling rate of hittable pitches taken doesn’t look much better:

As expected, Yoshida was pretty passive to start out the season, but he became more aggressive as he started to slump and never really recovered. Swinging at hittable pitches more often would be a good thing in a vacuum, but when taken into context with all the other things that were trending the wrong way during Yoshida’s second half, I’m not so sure it helped. Plate discipline is a fine balance between identifying bad pitches to take and being aggressive on good pitches to hit. Yoshida’s strengths seem like they’re more focused on the former, and when he became more aggressive, he threw that balance out of whack.

There were plenty of knock-on effects as Yoshida’s plate discipline deteriorated. Early on in the season, he was producing above average contact quality, helping him post a .174 ISO through the end of June. That metric dropped to .138 during the second half of the season as his contact quality collapsed along with his approach.

Despite seeing some decent results on balls in play in July, his contact quality took a steep dive in that month. Only a high BABIP and a couple of lucky home runs were able to buoy his production. His contact quality improved slightly in August, but he was hitting his batted balls at less than ideal angles, which led to far too many outs. Things got really interesting in September. His batted ball quality rebounded significantly with his highest expected wOBA on contact of the season coming during that month. Unfortunately, his actual results on those batted balls lagged well behind his expected stats. On top of that, he made far less contact that month, when he struck out 23.5% of the time. Still, it’s encouraging to see that his contact quality improved during the final month of the season, even if his discipline hadn’t recovered.

With this additional context, we can paint a pretty clear picture of Yoshida’s season. He started the season with his established approach and things were going well for him. In July, that approach started to unravel as he started swinging much more aggressively. His results on balls in play boosted his batting line that month, but everything collapsed once those hits stopped falling in. When he started slumping, he abandoned his extremely selective approach and his plate discipline never recovered. By the end of the year, his approach was completely unrecognizable from what it was in Japan.

With a full year of experience in the majors now under his belt, Yoshida has a better understanding of what to expect moving forward. His offseason training program was designed to better prepare him for the grind of a major league season, and being less fatigued should make it easier for him to return to form the next time he struggles. As he heads into his second year in the majors, he will need to lean on his excellent pitch recognition skills to sustain his success and pull him out of a slump when he goes cold. And when he inevitably scuffles again, he’ll need to remember why those skills are so critical to his success, so he doesn’t lose himself again.

Worried that civilization is going to come to an end this year? Fear not. The Red Sox and Brewers have both made big bets that life will go on in 2025. Boston has signed reliever Liam Hendriks to a two-year, $10 million contract with a mutual option for 2026. In Milwaukee, Brewers ace Brandon Woodruff, who was non-tendered in November, will remain a Brewers ace for the time being; Jon Heyman reported Monday morning that Woodruff and the team were in agreement on their own two-year contract, the terms of which are as yet undisclosed.

Based on their performance over the past several seasons, both Hendriks and Woodruff would probably be in line to make way more money on much longer-term deals if either one were expected to pitch in 2024. Woodruff made only 11 starts in 2023 and underwent shoulder surgery in October. Hendriks underwent treatment for non-Hodgkin’s lymphoma last offseason; cancer defeated, he returned to the field in May. His comeback was as short-lived as it was widely celebrated, though; less than two weeks after his first outing of 2023, Hendriks’ elbow started barking. The dreaded forearm strain turned into the even-more-dreaded torn UCL, and the avuncular Australian had Tommy John surgery in early August. Read the rest of this entry »

Kyle Teel is well positioned as Boston’s catcher of the future. Drafted 14th overall by the Red Sox out of the University of Virginia last summer, the backstop, who turned 22 last week, enters his first full professional season as the fifth-ranked prospect in Boston’s farm system and no. 80 on our Top 100. According to our lead prospect analyst Eric Longenhagen, Teel “presents a well-rounded overall profile” that includes “a fabulous offensive résumé.”

His 2023 numbers were certainly exemplary. Teel slashed .407/.475/.655 with 13 home runs in his junior year at UVA, helping earn him first-team All-American accolades and rocketing him up draft boards. Upon reaching pro ball, his left-handed stroke produced a .363/.483/.495 slash line and a 173 wRC+ in 114 plate appearances across three minor league levels, his last stop being Double-A Portland.

Defense is, of course, a major responsibility for catchers. Last month, when Teel was at Fenway Park for Boston’s rookie development program, I spoke with him about his preparation and setup behind the plate, his throwing, and his offensive profile.

David Laurila: Catching is a science as well as an art. With that in mind, what role does data play in what you do defensively?

Kyle Teel: “I really like data when it comes to how pitchers’ stuff moves, and heat maps on what to throw to certain guys at certain times. That’s obviously beneficial, but there is also nothing like the feel of the game. You need to be using your eyes and seeing what you can take in, in the moment. But the data is definitely important. Before every game, I look at what pitchers like to throw, their tendencies in certain counts, and things like that. That’s both as a catcher and when I’m hitting.”

Laurila: Do you think like a catcher when you’re in the batter’s box?

Teel: “I kind of do. There are benefits to doing that, just knowing how pitchers work and what guys tend to throw in certain counts. Overall, I would say that having a good feel at the plate and calling pitches is very similar.”

Roman Anthony arguably has the highest upside in the Boston Red Sox system. Three months shy of his 20th birthday, the left-handed-hitting outfielder is No. 14 on our recently-released Top 100, and in the words of Eric Longenhagen, he “has the offensive foundation (plate discipline and contact) to be a top five prospect if he can more readily get to his power in games.”

Getting to more of his in-game power was an organizationally-driven goal throughout a first full professional season that saw the 2022 second-rounder begin in Low-A Salem and finish in Double-A Portland. Progress was made. Of the 14 home runs Anthony swatted over 491 plate appearances, all but one came from mid-June onward. Learning to lift was the key and, according to the youngster that came not from an overhaul of his mechanics, but rather from subtle adjustments.

“At the beginning of the year, I was pulling it on the ground a little more than I would like to,” acknowledged Anthony, who was 200-plus plate appearances into the season when he went yard for a second time. “But I worked with my hitting coaches and eventually it clicked. It was really just minor tweaks. It’s not as though I was redoing my swing, or anything like that. I still have pretty much the same swing I’ve always had.”

According to Red Sox farm director Brian Abraham, Anthony’s adjustments were crafted primarily in a batting cage with simple, yet creative, drill work. Read the rest of this entry »

Corey Kluber announced his retirement on Friday, bringing the curtain down on an exceptional career whose later years were so often curtailed by injuries. Kluber pitched in the majors for parts of 13 seasons, but topped 100 innings just seven times, six in a row from 2013–18 and again in ’22. Within that limited timeframe, he made three All-Star teams and won two Cy Youngs, with a pair of top-three finishes and a ninth-place finish as well. His 2016 postseason run came up just short of ending Cleveland’s long championship drought. His is a career worth celebrating and putting into context, as his best work stands alongside that of a handful of Hall of Fame contemporaries.

Because he spent half a decade at the front of Cleveland’s rotation, it’s easy to forget that Kluber was actually drafted by the Padres, who chose him in the fourth round out of Stetson University in 2007. He climbed to Double-A San Antonio by 2010; on July 31 of that year, he was part of a three-team trade, heading to Cleveland while Jake Westbrook was sent from Cleveland to St. Louis, Ryan Ludwick from St. Louis to San Diego, and Nick Greenwood from San Diego to St. Louis. After a cup of coffee in late 2011, Kluber spent the first two-thirds of the next season at Triple-A Columbus, then joined the big club’s rotation in August. Read the rest of this entry »

The best pitch in baseball is a well-located four-seam fastball. It is the rhythm guitar of pitching, the rock upon which the church is built. To establish the fastball first is fundamental; to pitch any other way is backwards.

Maybe you don’t need it at all.

In the late 20th century, rock and roll evolved into different popular forms that either de-emphasized the role of the guitar or eliminated it altogether. Some artists went forward and embraced electronic instruments; others went back in time and rediscovered the piano. Of the 603 pitchers who threw at least 250 pitches last year, 49 didn’t throw a single four-seamer. Many of them were quite successful. The anti-four-seamer crowd includes top relievers like Josh Hader, Camilo Doval, and José Alvarado, as well as elite starters like Corbin Burnes and Framber Valdez. Read the rest of this entry »

Richard Fitts is a big right-hander hoping to do big things in a new organization. He has a chance to do just that. Acquired by the Boston Red Sox from the New York Yankees in December’s Alex Verdugo trade, the 6-foot-4, 245-pound Auburn University product is coming off a season where he logged a 3.48 ERA and fanned 163 batters in 152-and-two-thirds innings with Double-A Somerset. A 2021 sixth-round pick slated to begin the forthcoming campaign in Triple-A, he ranks among the top starting pitcher prospects in the Red Sox system.

Fitts discussed his game earlier this month when Boston held its annual Rookie Development Camp at Fenway Park.

David Laurila: Let’s start with how you approach your craft. Are you a pitching nerd?

Richard Fitts: “I’d like to be considered a pitching nerd. I’m by no means a genius, but I take a lot of pride in trying to get better every single day, and that includes figuring out the ins and outs of what can make me the best that I can be.” Read the rest of this entry »

Billy Wagner has a chance to be voted into the Hall of Fame this year. As I type these words on Saturday evening, the erstwhile left-handed reliever — this in his penultimate appearance on the BBWAA ballot — is polling at 80.0% with nearly half of the electorate having disclosed their choices. If he finishes at or above the 75% threshold required for induction he will become the ninth closer enshrined in Cooperstown.

Many will argue that closers — at least not those named Mariano Rivera — don’t belong in the Hall of Fame. The reasoning, by and large, is lack of innings thrown (Wagner has just 903), which factors into comparably low WAR totals (Rivera has 38.6, whereas workmanlike starters such as Kenny Rogers and John Lackey are north of 40). Add in a rule that allows for what might be deemed “cheap saves” and the argument against closers is understandable.

Personally, I don’t think there are enough closers in the Hall of Fame. It’s not as though the role isn’t important, and it certainly isn’t recent. The first 15-save season came exactly 100 years ago, with Firpo Marberry doing the honors with the Washington Senators (the right-hander added two more saves in that year’s World Series). Marberry subsequently logged the first 20-save season in 1926, and by career’s end he’d led the American League in saves and appearances six times each. Marberry isn’t in the Hall of Fame, but when you factor in his historical significance — ditto his higher JAWS score than all of Rollie Fingers, Lee Smith, and Bruce Sutter — he arguably should be.

If a “closer” with Marberry’s statistical résumé — he finished with 99 saves and 148 wins (56 of them as a reliever) — could be deemed Hall-worthy, what about a Wagner contemporary like John Franco? While not as overpowering as Wagner, Franco did amass 424 saves — two more than the on-the-doorstep Hall of Famer’s total, and the most ever for a southpaw. Moreover, it ranks fifth-most all-time, while his 1,119 appearances ranks third-most. With the caveat that JAWS isn’t bullish on his credentials, Franco presents an intriguing case.
