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.

Welcome back baseball! After an exciting and dramatic World Baseball Classic to whet our appetites, the main course is finally here. I introduced these power rankings a few years ago as a way to think about all 30 teams in baseball and stack them up against each other outside of the rigid structures of leagues or divisions. Nearly every major site has some form of power rankings, usually derived from whatever panel of experts each site employs. These rankings, though, are entirely data driven.

A reminder for how these rankings are calculated: first, we take the three most important components of a team — their offense (wRC+), their pitching (a 50/50 blend of FIP- and RA9-, weighted by starter and reliever IP share), and their defense (RAA) — and combine them to create an overall team quality metric. For these offseason power rankings, I’ve used each team’s projected stats based on their Depth Charts projections which are now powered by our blend of ZiPS and Steamer projections. I’ve also used the projected fielding component of WAR that appears on our Depth Charts projections as the defensive component for each team in lieu of RAA.

The Braves haven’t budged from the top of these rankings throughout this offseason. Sure, the Mets spent a ton of money this offseason, and the Phillies just went to the World Series, but Atlanta has owned this division for the last half decade. There are still some lingering questions, however. Orlando Arcia likely isn’t the long-term solution at shortstop, but both Vaughn Grissom and Braden Shewmake were optioned to Triple-A last week; the former has some defensive issues to work through, and the latter needs more exposure to high-level pitching before being handed a job in the big leagues. There are also some injury concerns in their pitching staff, with both Kyle Wright and Raisel Iglesias dealing with shoulder issues this spring and Michael Soroka not fully recovered from his many maladies. Still, this team is loaded with young talent and poised to win its sixth consecutive division title.

The big storyline for the Yankees this spring has been the competition for starting shortstop, with top prospect Anthony Volpe earning a spot on the Opening Day roster. That should provide youthful excitement to cover the very real concerns in the rotation and outfield. Harrison Bader likely won’t be out for long with his strained oblique, but his absence has revealed how shallow the position group is when Aaron Judge has to slide over to center field. And injuries of varying severity to Carlos Rodón, Luis Severino, and Frankie Montas aren’t exactly how you want to start off the season. Read the rest of this entry »

Some pitchers approach their craft by trying to hone their established pitch repertoire to make the most of what they’ve always thrown. Then there’s Logan Gilbert. Rather than stick with the pitches that were the foundation of his success in college and through the minors, he’s consistently tinkered with new grips and new pitches to enhance his arsenal, even after reaching the big leagues. Last year, he revamped each of his secondary offerings in an attempt to gain more consistent effectiveness with them. He hasn’t been afraid to make adjustments on the fly during the season either, all in an effort to maximize his abilities on the mound.

This spring, Gilbert debuted a brand-new splitter to replace his changeup. That older pitch was effective in limited action, but he rarely had a good feel for it, making it an inconsistent offering at best. “I’ve always tried the changeup and just kind of struggled with it, [it] just wasn’t natural for me,” Gilbert said in an interview with Daniel Kramer of MLB.com. “So I’m just trying to find basically a variation of a splitter that I can throw like a fastball.”

Before we get too deep into his new pitch, I want to go back and look at how Gilbert’s entire repertoire has evolved over the last two years. To do so, I’m going to be using the new Stuff+ leaderboards recently introduced on the site. Stuff+ is a pitch model developed by Eno Sarris and Max Bay that attempts to quantify the quality of a given pitch using only the underlying physical characteristics of said pitch. Stuff+ becomes reliably predictive very quickly — in under 100 pitches — and is extremely sticky year-to-year. That reliability means it’s sensitive to changes in a pitch’s characteristics, making it an excellent tool to evaluate someone like Gilbert.

The one constant for Gilbert has been his fastball, which possesses excellent raw velocity that plays up even higher when you take into account his elite release extension. With above-average ride and good command, his heater has been the backbone of his pitch mix. If anything, he’s leaned on it a little too much early in his career, but only because his secondary offerings have lagged behind. The graph above puts the inconsistency of those pitches in stark relief. His changeup finally found some sure footing last season, even if he couldn’t command it at all. More importantly, his two breaking balls have oscillated in effectiveness, with neither registering above average at the same time. Read the rest of this entry »

It has been a pretty quiet offseason in Seattle. The Mariners got things moving fairly quickly, trading for Teoscar Hernández and Kolten Wong to cover the holes left by a couple of departing free agents, but things slowed down after that. They’ve brought in a couple of veterans to provide a bit of depth, but are otherwise largely banking on a repeat of their success last year and some continued growth from their young core. They made one more last minute addition yesterday, signing Kole Calhoun to a minor league contract with an invitation to spring training.

Bringing in an 11-year veteran like Calhoun is the type of move that plenty of teams make during the spring, but they rarely work out for the player involved. Most ball clubs are content to roll out whatever internal depth they already have instead of clearing a 40-man roster spot to add a player on a minor league deal. But every once in a while, a veteran will show that he has just enough left in the tank during spring training to break camp on the Opening Day roster.

If you squint, you can see how Calhoun could be primed for a bounce back season in 2023. A long-time Angel, he really started to struggle during his final seasons in Anaheim. From 2017–19, he put up a 94 wRC+ and accumulated 3.5 WAR, with a career-high 33 home runs in his final season for Los Angeles. He joined the Diamondbacks in free agency the following year and produced a career-high 125 wRC+ and 1.5 WAR during the shortened season. The last two years haven’t been kind to him, however. A recurring hamstring injury cut short most of his 2021 season and his production cratered last year after signing a one-year deal with the Rangers, with his wRC+ falling to a career-low 67.

The Dodgers have had a fairly quiet offseason by their recent standards. Because they are set to exceed the competitive balance tax threshold for the third consecutive season, any spending over the $233 million limit will carry a 50% tax. As a result, Los Angeles has settled for smaller moves, bringing in Miguel Rojas via a trade with the Marlins and signing a couple of veterans to one-year deals. They added another free agent to that group on Friday, inking David Peralta to a one-year, $6.5 million contract with incentives that could bring the total to $8 million.

A long-time member of the Diamondbacks, Peralta peaked in 2018 with a 130 wRC+ and a career-high 30 home runs. In the three years after that breakout, he fell back to being a league average hitter with good plate discipline and decent power. A late-ish bloomer who converted away from the mound after he had already made his professional debut, the 35-year-old was never going to fit into Arizona’s rebuilding plan despite becoming a fan favorite in the desert.

The beginning of spring training is just a week away, and the majority of the big moves this offseason have already happened. There are a few free agents left looking for a new home, but for the most part, teams have set their spring rosters and are looking forward to sifting through their guys as they work toward Opening Day. Now that the ZiPS projections have been plugged into the site and the hot stove is set to a preseason simmer, I thought it would be a good time to revisit these power rankings to check in on how teams did over the offseason. You could think of the Delta column as a rough grade, since it reflects the change in ranking from the last time these ran in mid-November.

A reminder for how these rankings are calculated: first, we take the three most important components of a team — their offense (wRC+), their pitching (a 50/50 blend of FIP- and RA9-, weighted by starter and reliever IP share), and their defense (RAA) — and combine them to create an overall team quality metric. For these offseason power rankings, I’ve used each team’s projected stats based on their Depth Charts projections which are now powered by our blend of ZiPS and Steamer projections. I’ve also used the projected fielding component of WAR that appears on our Depth Charts projections as the defensive component for each team in lieu of RAA. Read the rest of this entry »

Back in 2020, MLB implemented a number of rule changes, both planned and forced by the pandemic-shortened season. Among them, none had the potential for dramatic change but with little actual effect on the game as the three-batter minimum rule. It was an inelegant solution to an infrequent problem: Subsequent investigation after its implementation has shown that the rule hasn’t addressed the pace-of-play issues at the heart of its intended effects.

Where the rule has had an outsized effect is in roster construction. Upon implementation, the value of a certain type of reliever — the Lefty One Out Guy (LOOGY) — was extinguished. Not that there were many LOOGYs left anyway, and the impact they had on games was fairly negligible in the grand scheme of things. This side effect of the rule was foreseen but still unfortunate nonetheless.

While the left-handed specialist has all but disappeared from major league rosters, left-handed relievers in general have felt the effects of this rule change as well. In 2022, southpaw relievers pitched around a quarter of all relief innings, which is right in line with the previous decade of usage. Unsurprisingly, more and more of those outings have come against right-handed batters. In 2013, nearly half of the batters left-handed relievers faced were left-handed as well. Last year, that rate fell to just over a third. Read the rest of this entry »

Since breaking into the big leagues back in 2011, Lance Lynn has featured one of the most fastball-heavy approaches in the majors. Now, that’s a little reductive, as he throws three different fastballs that he can ride, cut, or sink depending on what the situation calls for. Still, over 80% of the pitches he’s thrown in his career have been classified as a four-seamer, sinker, or cutter; that’s the third-highest rate of hard stuff thrown by a starter since his debut. And Lynn’s approach has only been amplified in recent seasons. In the last five years, over 85% of his pitches have been fastballs; no other pitcher has crossed the 80% mark.

When Lynn isn’t throwing a heater, he mixes in a curveball and a changeup, though neither pitch has been all that effective during his career. His four-seamer is a devastating pitch up in the zone, and his cutter and sinker allow him to work laterally to either side of the plate if needed. Utilizing all three of his fastballs effectively leaves little room for secondary offerings in his pitch mix. Why change an approach that’s worked for more than a decade?

Baseball is a game of constant adjustments, particularly in the context of the pitcher-batter duel at its center. In December, after announcing he’ll be pitching for Team USA in the World Baseball Classic, Lynn gave a fascinating quote about the adjustments he’s had to make in an interview with The Athletic’s James Fegan:

“People get so caught up in ‘Oh, you just throw fastballs.’ If you actually pay attention to the game, there’s speed differentials, there’s bigger breaks or smaller breaks. Part of evolving as a pitcher is giving the hitters different looks. Over time, you’re locking in the things that make you good, and you’ve got to figure out things that are maybe not as good as they can be. Over the last couple of years, Ethan [Katz] and I have been able to really concentrate on grips, different spin axes, and things of that nature that have really helped develop a pitch that comes out of a slot where it gives hitters difficulty.”

After a promising end to their 2021 season, the Detroit Tigers made a few big splashes in free agency to support a wave of young prospects on the verge of making their big league debuts. Instead of continuing to build on that momentum, however, Detroit took a huge step backwards last year, losing 96 games while scoring the fewest runs in the majors. Their new additions, Javier Báez and Eduardo Rodriguez, combined for just 2.6 WAR, and their top position player prospects, Spencer Torkelson and Riley Greene, had rough introductions to the big leagues. This cyclone of disappointment led to the dismissal of long-time general manager Al Avila and a bevy of questions about the direction of the franchise.

There are plenty of problems new president of baseball operations Scott Harris needs to address on the roster and in the organization. The early-career struggles and future development of Torkelson and Greene loom the largest, however. As prospects, those two were seen as can’t-miss, heart-of-the-order bats who would form the core of the next great Tigers lineup. Instead, their disappointing rookie seasons were a significant contributor to that league-worst offense in 2022.

Torkelson and Greene are both under 24 years old and will have plenty of opportunities to develop into the kind of contributors that reflect their status as former top prospects. Still, it would behoove Detroit to give them every advantage to succeed in the big leagues, leaving no stone unturned. To that end, the Tigers announced on Wednesday that they would be making some adjustments to the dimensions of Comerica Park ahead of Opening Day:

We’re adjusting @ComericaPark’s outfield dimensions and lowering wall heights in key areas prior to Opening Day 2023.

Last January, inspired by Cedric Mullins’s 2021 decision to stop switch-hitting, I tried to identify other switch-hitters who might benefit from swinging from one side or the other. Going beyond simply calculating the largest platoon splits, I relied on handedness splits for some of the players’ key underlying batted ball and plate discipline metrics. The idea was that there could be a path to improvement if these switch-hitters eliminated their severe underperformance from one side of the plate. Of course, the other option is simply to work on their weaker swing and become a better overall switch-hitter.

One of the batters I identified as a candidate to hit left-handed full-time was Ian Happ. Through 2021, Happ had posted a 55 point platoon split, the second-highest among the 25 switch-hitters in the sample. Happ crushes right-handed pitching from the left side, but all of his batted ball peripherals are significantly weaker when swinging from the right. Instead of taking my advice (thank goodness), Happ posted the best season of his career against left-handed pitching in 2022:
