How do you explain a fall in performance from a superstar player in their age-24 season? It’s hard to make any concrete conclusions, but there are always certain observations that can help us understand what happened, and when it comes to Ronald Acuña Jr., many of us are eager to know. In the first four seasons of his career, he was undeniably one of the best players in baseball, and in the last two, albeit both shortened for different reasons, his power had begun to take off. In 2020 and ’21, before he tore his ACL, he maintained an ISO above .300.

Oh yeah, about that ACL. It’s not a common injury in baseball, so we don’t have much history to go off, but there is no denying its impact on Acuña’s swing and athleticism. Depending on the stage of your career and sport you play, an ACL tear can impact you differently. When it came to Acuña, a special athlete, I thought there would be an immediate bounce back. Perhaps that was an unfair assessment. This is a major injury for such an explosive player, and it’s understandable that it would take time to recover and get the necessary level of proprioception back. That’s not to say he wasn’t successful in 2022; he put up three months with a 130 wRC+ or better and ended at 114 overall. But that isn’t close to his pre-2022 career mark of 140. I’m confident he can get back to that point. How? He’ll have to reignite his ability to keep the ball off the ground and in the air.

Sorry to simplify things so much. It’s a personal pet peeve of mine to say a hitter just needs to stop hitting so many groundballs; it’s such an obvious suggestion for any hitter or swing type. But it’s the case here. From 2019 to ’21, Acuña didn’t have a ground ball rate above 38%; in ’22, that figure skyrocketed to 47.7%. That was a career high, 5.4 percentage points higher than his rookie season. Even in the months where he was stellar, it wasn’t because he returned to his previous batted ball profile; he only had one month all year with a groundball rate under 42%.

During Game 3 of the ALCS, Jeff Francoeur noted that 10 of the 12 pitchers who had surrendered postseason home runs to Alex Bregman were All-Stars, eliciting a comment about how Bregman hits well against good pitching. That’s undoubtedly a fun fact, but the notion has been rattling around my brain for the last couple weeks. I’ve definitely heard stories about players who hit good pitching, but I’ve never heard of anyone looking at splits based on the quality of the pitcher on the mound.

The main problem with that idea is a logical one. Break down any batter’s performance into its constituent parts, and you’ve entered a zero sum game. If you’re at your best against great pitchers, that means you’re hitting worse against everyone else. It’s hard for me to imagine that there are many players who fare better against Justin Verlander than they do against, well, anyone on the Nationals.

There could be players who are less bad than average, but if I had my choice of superpowers, I’m not sure that’s the one I’d pick. It would definitely help out in the playoffs, but over the course of the season, batters see a lot more average and poor arms than they do great ones. I’d rather perform well the majority of the time. Read the rest of this entry »

Another Pirates reliever has been picked up by the Yankees, and his name is Junior Fernández, owner of 54 career innings pitched in the majors with St. Louis and Pittsburgh. This past season, he finished with a 5.79 FIP in 18.2 innings; his career FIP sits at 5.57, so he hasn’t had much success in the league so far. So what exactly do the Yankees see in him?

Like many relievers in the Yankees’ bullpen, Fernández throws high-velocity sinkers and boasts an above-average ground ball rate: 58.9%, a very similar clip as Jonathan Loáisiga. That all sounds very similar to another Yankees pickup from the Pirates: Clay Holmes. But Holmes’ sinker is of the turbo ilk that forces its way down with bowling ball action; this past season, the vertical movement on that pitch was 21% above league average. Fernández’s is much more vertical neutral. In fact, the comparison to Loáisiga is much more appropriate. The table below shows how Fernández’s sinker specs compare to Loáisiga’s:

The two pitchers have similar extension, release points, and movement profiles. The entry into the zone in terms of horizontal and vertical approach angles isn’t all that far off either. Overall, we’re looking at very similar pitches, and Fernández throws his even harder by about a tick. This alone is a good starting point to explain why the Yankees were interested enough to scoop him up off waivers. Read the rest of this entry »

Blake Sabol has versatility, Pittsburgh ties, and a bat that could be providing thump to the Pirates’ lineup in the not-too-distant future. A left-handed-hitting catcher who also plays the outfield and first base, Sabol, 24, is coming off a season where he slashed .284/.363/.497 with 19 home runs between Double-A Altoona and Triple-A Indianapolis. The seventh-round selection in the 2019 draft has other notable qualities, as well. Along with being a stat nerd, the former University of Southern California Trojan has an engaging personality that promises to make him a fan favorite if he reaches the majors.

Sabol, who is Rule 5 eligible, talked about his multi-faceted game and his connections to the city he hopes to soon play in during his recent stint with the Arizona Fall League’s Surprise Saguaros.

———

David Laurila: I understand that you play multiple positions and have put up some good offensive numbers. How do you see yourself?

Blake Sabol: “Defensively, I kind of consider myself a Swiss Army Knife. I’m primarily a catcher, but I can be in the outfield and have also been taking some ground balls at first base. I’m hoping to be like a three-level player.

“With the bat, I’ve had a couple of good seasons under my belt — I’ve been able to hit for power and have a good OPS — so I feel I can impact the game that way. I think I can help a big league team. Instead of having a guy who is only a catcher, maybe just a backup catcher, I can be playing multiple spots, or even be in the lineup as a DH.”

Laurila: Your goal isn’t to be a starting catcher in the big leagues?

Sabol: “My goal is ultimately to be in the big leagues, anyway, anyhow. I mean, I would love to be a catcher. There’s a lot of value there, and I think I could do it. But ideally, and I’ve talked with Henry Davis about this, even if we’re splitting games behind the plate, I can go in the outfield or be a first baseman. I just want to be in the lineup as much as possible.” Read the rest of this entry »

Once you get past Aaron Judge, this offseason’s free agent outfield class gets real thin real fast. Brandon Nimmo is a very good player, but not a power threat, and after him and maybe Mitch Haniger, you get into the Michael Conforto–Cody Bellinger zone with alarming speed. “I can fix him” is as risky a conceit in baseball as it is in romance.

Andrew Benintendi sits in a bit of a no-man’s land between Nimmo and the true reclamation projects. There will be a team that misses out on Judge and Nimmo and finds itself with a hole in an outfield corner and about $15 million a year to spend to fill it; Benintendi will likely be the beneficiary of that vacancy when it emerges.

The sales pitch for Benintendi is pretty simple: At 28, he’s hitting the market fairly young and could command a deal as long as four years without including much of his decline, if any. He’s a capable defender in a corner who posted a career-high .373 OBP last year, which for what it’s worth was a hair higher than Nimmo’s, and has had a few monster seasons in the past, including a 20-20 campaign in 2017 and a nearly-5 WAR year the following season.

But there are drawbacks. When he was drafted seventh overall out of Arkansas in 2015, the question about Benintendi was, “How does such a teeny, tiny man hit so many home runs?” Twenty home runs, to be precise, in just 65 games, along with a .717 slugging percentage. That power has never showed up in the majors for Benintedi, whose career high in homers is exactly 20 in 151 games, and what moderate power he once had is going away. Read the rest of this entry »

Last week, I contemplated baseball as a carnival game. It gave me great joy because I think there should be more silly games in the world. It also gave me great joy because I got to spend hours watching beautifully located pitches, on a loop, for work. I wouldn’t necessarily recommend trying this yourself – bosses are wild these days – but trust me, it’s really fun.

Another thing I really enjoyed in writing that article was watching batters react to those perfectly placed pitches. One, in particular, stuck with me, so I snuck a piece of it into the piece. Here’s the full clip. In it, Vladimir Guerrero Jr. has either just realized he had a huge cryptocurrency position on FTX or been called out on strikes:

I love it. I love it so much. It makes me even happier that he wasn’t right. That was a strike! Everyone loves to think they’ve been wronged. Everyone has their own perspective. Vlad’s perception of the strike zone is surely that it smaller than the actual zone. In this case, the difference between perception and reality led to a delightful expression of disbelief.

Nolan Jones might be ready to break out in Colorado, and turning 4 o’clock into 7 o’clock is how he would go about doing it. His time in Cleveland over — the Rockies acquired the rangy 6-foot-4 outfielder from the Guardians earlier this week in exchange for Juan Brito — Jones heads west with a swing that is, by his own admission, compact in the cage and too long in the batter’s box. Striking an effective balance between the two is an ongoing goal and a key to his future success.

“I’ve got really long levers, so I’m trying to simplify my moves and make them more efficient,” Jones told me earlier this summer. “Like anybody else, my moves become bigger in the game, and when your limbs are long, a two-inch move in the cage can become a six-inch move. My swings in the cage are those toned-down moves. I’m trying to be shorter to where, when they get bigger in the game, they’re right where I want them to be.”

Reaching his potential has been a frustrating endeavor for the 24-year-old. Selected in the second round of the 2016 draft out of Philadelphia’s Holy Ghost Preparatory School, Jones has ranked as Cleveland’s top prospect multiple times, and he was No. 51 in our Top 100 as recently as the spring of 2021. What has largely held him back is a penchant to swing-and-miss, a trait that accompanied him to the big leagues this season. Along with a .244/.309/.372 slash line over 94 plate appearances, the rookie had a 33% strikeout rate and a worst-on-the-club 71.6% Z-contact rate. Given the Guardians’ preference for hitters who can consistently put the ball in play, Jones no longer fitting into their plans comes as no surprise. Read the rest of this entry »

Mini trade alert! Yesterday, the Seattle Mariners sent outfielder Kyle Lewis to the Arizona Diamondbacks in exchange for outfielder/catcher Cooper Hummel. That’s the entire exchange – no other players, no cash, just a one-for-one swap. It’s not terribly exciting, but its simplicity makes it easier to break down. Shall we?

Two years ago isn’t a lot, but considering all the ruckus that has occurred between then and now – and I’ll spare you the loathsome, often non-baseball-related details – it might as well be forever. That’s also when Lewis won American League Rookie of the Year. After a lengthy detour caused by persistent knee injuries, Lewis seemed on a sure path to becoming an integral part of an up-and-coming Mariners core. But the hardship continued into his sophomore season due to another tear to the same knee that had been bothering him for years; he played just 36 games in 2021. And if that wasn’t enough, the already battered Lewis, who began his 2022 on the injured list, was hit by a pitch a mere week after being called up in May. He recovered, but struggled immensely at the plate. Eventually, the Mariners sent him back down to Triple-A Tacoma, where he wrapped up a grueling season.

Laid in front of us are four fragmented seasons, including a cup of coffee in 2019, from which to evaluate Lewis. The truth is, it’s a tricky task. When samples are small and distant from one another, distinguishing the effects of injury from random variance and a possible decline in skill is about as productive as imagining “what could have been.” But from a projection system’s perspective, a short resume actually paints Lewis in a positive light. Steamer, for example, forecasts a .240/.323/.426 slashline and a 110 wRC+ for 2023, likely because of his recent minor league output and the fact that most of his major league experience comes from an award-winning rookie season. The ceiling of an everyday center fielder still exists, and a 116 wRC+ in Triple-A last season that wasn’t BABIP-driven is reason for optimism. Read the rest of this entry »

Thad Ward should be of interest to several teams come next month’s Rule 5 draft. Currently no. 15 on our Boston Red Sox prospect rankings with a 40+ FV, the 25-year-old right-hander wasn’t added to the club’s 40-man roster — a decision that left Eric Longenhagen “a tad surprised.” Our lead prospect analyst explained that Ward “looked good in the Arizona Fall League, locating 92-94 mph fastballs while mixing in two above-average breaking balls… [and] looks like a possible bulk relief fit right now.”

Three years ago, Ward looked to be well on his way to securing a spot in Boston’s starting rotation. When he was featured at FanGraphs in October 2019, the 2018 fifth-rounder out of the University of South Florida had recently been honored as the organization’s Minor League Pitcher of the Year. According to then-Red Sox pitching analyst Brian Bannister, Ward was in possession of “a Chris Sale slider.”

But fate had its say. The 2020 minor league season was canceled due to the pandemic, and the following year, Ward underwent Tommy John surgery after making just two starts with Double-A Portland. By the time he returned to action this past July, he had essentially missed two-plus seasons. But while taking the mound again didn’t feel akin to jumping back on a bicycle for the righty, he did pitch well. In 51-and-a-third innings spread across four levels, Ward fanned 66 batters and allowed just 40 hits while logging a 2.88 ERA.

Ward discussed his comeback, including how his stuff compares to what it was pre-injury, during his stint in the Arizona Fall League.

———

David Laurila: You came back from Tommy John this year. Are you the same pitcher now that you were before going under the knife?

Thad Ward: “In some ways, yes. In some ways, no. I’ve matured a lot in terms of stuff I can’t control. I don’t get as upset over mistakes. That’s not to say my competitive edge has gone away, it’s more that I feel I’m channeling it in a better direction.” Read the rest of this entry »

Last week, I wrote about the overcrowded NL MVP ballot. Eight different position players finished within 1.0 WAR of the top spot on our leaderboard, more than in any other year since WAR was introduced. The MVP nearly always goes to one of the top position players by FanGraphs WAR. Thus, this past year presented us with one of the most hotly-contested MVP races in recent memory, regardless of how voters ultimately cast their ballots.

To have so many worthy choices for the award is exciting, even if we already know that Paul Goldschmidt emerged as the winner, with Manny Machado and Nolan Arenado placing second and third, respectively. As I wrote last Friday, “such a close race between so many contenders compels us to look beyond the go-to methods we might normally rely on to pick a winner. It allows us to think about how we measure value. It’s a chance to get creative.” I don’t know about you, but that sounds like a fun challenge to me. Now, from the headline and the image at the top of this piece, you can already guess who I would’ve picked. But indulge me for just a moment longer so I can explain how I came to that decision. On a ballot full of deserving choices, how was I to single out one name as the most deserving of all? Read the rest of this entry »
