Say this for the White Sox: They scored runs on Thursday. Sure, they were thrashed 14–5 by the Rays, which extended their losing streak to eight games, but they ended their scoreless streak at 25 innings, scored more runs than they had in the previous four games (three), and matched their total of hits from the previous three games (11). When you’ve lost 13 out of your last 15 games, this counts as progress.
Chicago’s current skid has dropped the team’s record to 7–19, the third-worst in the majors. There’s no ambiguity about whether the White Sox are bad: they also have the third-worst run differential and projected winning percentage, according to both PythagenPat and BaseRuns:
Bryson Stott began this season with a 17-game hit streak, marking a new Phillies franchise record to start a season. Eleven of those games were multi-hit efforts, culminating in 29 hits across his first 81 plate appearances. He’s added a handful of hits since his streak ended on April 18 and his overall line now stands at .339/.368/.459, good for a 126 wRC+. His early season success has been one of the few bright spots for the Phillies as they deal with a a variety of woes.
While Stott’s hot start is being at least partially driven by some fortunate results when he has put the ball in play — his BABIP currently stands at .417 — his success is also the culmination of a number of adjustments he’s made since making the Opening Day roster as a rookie last year. His initial exposure to the big leagues didn’t go very well. He collected just four hits across 31 plate appearances and was demoted to Triple-A on April 20 after playing in just nine games in the majors. Upon getting recalled on May 8, he continued to struggle until making an adjustment to his swing. Read the rest of this entry »
There’s a new pitch classification, well, sweeping the nation, and with the aptly-named sweeper comes a lot to learn about its behavior, usage, and effectiveness. For those catching up, the sweeper, which Statcast introduced to its pitch classification system this spring, is a breaking ball that plays more on the horizontal plane than the vertical one, typically thrown slower and with more break than a slider, “sweeping” across its path rather than dropping the way a traditional curveball might. The rarer slurve, on the other hand, breaks horizontally like a sweeper but also features more downward break. While the slider classification had become a bit of a catch-all for pitches that break horizontally, which vary tremendously in velocity and depth of the break, the introduction of the sweeper classification helps to differentiate the breaking ball by both the type and the amount of horizontal break. For reference, here’s what the average sweeper, slider, curveball, and slurve have looked like so far this year:

As many have noted, this isn’t a new pitch so much as it is a recognition of trends toward a pitch that was already there. Over the last seven seasons, the percentage of breaking balls that broke at least a foot to the pitcher’s glove side has risen from 17.7% in 2017 to 27.4% so far this year, including a seven-point increase in the last two seasons. Meanwhile, the average vertical drop (without gravity) on those breaking balls has shrunk from -5.9 inches as recently as 2019 to just -2.0 so far this year. Over the last few years, pitchers have been sending more and more breaking balls veering across the strike zone without dropping. Pitchers and teams have different names for the pitch – the Yankees call their version a “whirly;” Statcast now calls it a sweeper. Read the rest of this entry »
Welcome to another edition of five things that I liked (or didn’t like) in baseball this week. I got the idea for this column from Zach Lowe, who writes my favorite basketball column with the same conceit. This week’s edition is highlighted by superstars being superstars, pitchers trying everything they can to keep evolving, and, of course, my two favorite topics: bunts and errors. Let’s get to it.
1. Jacob deGrom’s Cold Fury
Order has been restored – Jacob deGrom is back from injury and is once again the best pitcher in baseball. After an Opening Day hiccup, he looks a lot like he did the last time he was terrifying opposing hitters: upper-90s fastball, wipeout slider, and pinpoint command that makes the whole thing feel vaguely unfair. In his past three outings, one of which was shortened thanks to a mini injury scare, he has 25 strikeouts and one walk. Even if you don’t want to separate it that way, he has 43 strikeouts and three walks on the year. It’s outrageous. Read the rest of this entry »
Ben Lindbergh and Meg Rowley banter about Drew Maggi’s major league debut and whether there should be a way for other journeyman minor leaguers to make the majors more easily, the story of short-lived Mariners mascot Spacey the Space Needle, the causes of a dramatic uptick in occurrences of catcher’s interference, Shohei Ohtani’s anti-pitch-tipping prowess, Jordan Walker’s demotion to the minors, the slow starts of the Cardinals and White Sox, and more, plus (1:17:03) a Past Blast from 1999 and a question about celebrities on major league rosters.
Robbie Ray did not replicate his 2021 AL Cy Young-winning form last year. In fact, he struggled down the stretch, but he did make a solid contribution as the Mariners ended their 21-year playoff drought. Alas, he won’t get to help them try to repeat that feat. On Wednesday, the Mariners announced that the 31-year-old lefty will undergo surgery to repair a torn flexor tendon and miss the remainder of the season.
After a promising spring training in which he restored some lost velocity to his four-seam fastball, Ray made just one start, and it wasn’t pretty. Facing the Guardians on March 31, he needed 26 pitches to complete the first inning, during which he issued back-to-back four-pitch walks to José Ramírez and Josh Bell before escaping by striking out Josh Naylor. His fastball velocity quickly diminished and he lasted just 3.1 innings, walking five and surrendering four hits and five runs (three earned).
In the immediate aftermath, Ray didn’t tell reporters that he had felt tightness in his forearm starting in the second inning, a problem that he attributed to the cold weather. After undergoing an MRI the next day due to lingering soreness, he was diagnosed with a Grade 1 flexor strain; only in discussing the injury with reporters did he reveal his discomfort.

After a fantastic run in the World Baseball Classic, Randy Arozarena has stayed red hot. Defensive metrics see him as a hair better in left field this year, and he’s also been slightly above average on the basepaths. That’s a big upgrade from the extremely entertaining but ultimately deleterious aggression he showed in 2022. Oh, and I should probably mention that he’s the eighth-best hitter in all of baseball right now, right behind some guy named Trout. Arozarena is running a 182 wRC+, up from his already very good career mark of 129. All three of the figures in his .348/.412/.584 slash line would be career-best marks over a full season. Put it all together, and Arozarena is currently on pace to double his career WAR total.
How is he doing all this? I’m not completely sure. Don’t get me wrong; the numbers tell a story, and there are some other convenient narratives at hand. I’m just not convinced of how everything fits together. That’s actually why I was so interested in writing about Arozarena. He’s way more fascinating than some guy named Randy has any right to be.
Let’s start with one thing we can be sure of: Randy Arozarena is absolutely hammering the baseball. He’s always been capable of posting eye-popping exit velocities, but this year he’s doing it consistently. Last year, his average exit velocity was 89.9 mph and his hard-hit rate was 40.7%, both solidly above average. This year he’s at 95.1 and 59.2%. That’s not just good; that’s Yordan Alvarez territory. In terms of contact quality, Arozarena has never had a stretch like this:
It’s not just that he’s hitting the ball harder than ever. He’s also avoiding mis-hits at a career-best rate. His 7% soft-hit rate is tied for seventh-lowest in the league, and none of the six players ahead of him has a higher hard-hit rate.
Arozarena is also lifting the ball more than ever. His line drive rate is at 20%, and his fly ball rate is at 38.6%. While both would be career highs over a full season, this isn’t completely unprecedented. Arozarena has had previous stretches with lower groundball rates, though combined with his elevated hard-hit rate, this one has led him to a career-best 16.9% barrel rate. What’s new is his launch angle tightness. Despite all this lift, his popup rate is at a career low. Arozarena’s average launch angle is up by 3.0 degrees, but the standard deviation of his launch angle is down by 3.3 degrees. He’s consistently hitting the ball where he can do the most damage, reaping all the benefits of an improved launch angle with none of the downside. Courtesy of Baseball Savant:
The last big change is that Arozarena is using right field like never before. Batters tend to elevate the ball more when they’re going the other way, but that’s not nearly enough to explain what’s going on here. His 36.6% opposite field rate is well above his 24% career average, and his pull rate is also at a career low. This is something entirely new. He’s now spraying the ball all over the field, and he’s never had a stretch where he’s gone the other way so frequently or pulled the ball so infrequently. Further, when he hits the ball to the right side, he’s hitting it with authority. His career average exit velocity on balls the other way is 88 mph. This year it’s 95.2 mph:

As you can see, Arozarena’s hard-hit rate is roughly unchanged when he pulls the ball. He’s hitting more grounders than normal to the left side, and he’s succeeding there partly by hitting the ball harder and partly through batted ball luck. However, on balls up the middle and to the opposite field, his hard-hit rates have skyrocketed and he’s hitting the ball in the air more than ever. In fact, the numbers indicate that his 229 wRC+ to the opposite field might actually be a bit lower than he deserves.
Arozarena’s profile has always been a little bit tough to parse. For example, take a look at the heat maps below. On the left is Arozarena’s career slugging percentage per ball in play. On the right is his contact rate:
Some of the pitches that Arozarena really crushes, like the ones at the top of the zone, are also the ones he swings through most often. In fact, if you take a closer look, you’ll notice that Arozarena also tends to have lower contact rates right in the middle of the plate, a trend that has continued this year. He’s capable of doing damage below the zone, or on pitches just off the plate outside.
I bring this up because this is the part of the article where I would normally dig into the underlying metrics and tell you that Arozarena is mashing the ball because he’s chasing less, getting ahead in the count, and taking advantage of meatballs in the zone. Or maybe that he’s just focusing on the pitches he can really crush. That’s how these things tend to work. And while Arozarena is in fact chasing less and seeing slightly more pitches in the zone, I don’t really think that explains the transformation in his batted ball profile.
Arozarena’s chase rate is 7.5 percentage points lower than it was last year. That’s a big drop, but it also leaves him right around his 2001 rate, and he wasn’t running a 180 wRC+ or a 60% hard-hit rate in 2021. He’s striking out a lot less and walking slightly more, but he’s also whiffing more often. In fact, he’s seen more strikes overall and spent a lower percentage of the time ahead in the count this year.
Arozarena’s overall contact rate is up slightly, though again, it’s not that simple. He’s making more contact in the zone and whiffing more when he chases. I don’t know how repeatable that is, but it’s a neat trick if you can pull it off. Combine it with a lower swing rate (particularly outside the zone), and all of sudden more of his batted balls come on pitches in the zone. But still, we’re only talking about an increase of 2.3 percentage points. That doesn’t sound like enough to explain a hard-hit rate that’s jumped nearly 20.
Here’s the bigger thing: Name a split, and within that split Arozarena is hitting the ball harder this year than he did last year. Ahead, behind, or even in the count? Randy Arozarena is hitting the ball harder. Inside or outside the zone? Randy Arozarena is hitting the ball harder. Heart, shadow, or chase zone. Fastball, breaking ball, or offspeed. Lefty, righty, home, away, fly ball, groundball, line drive; he’s even hitting his popups harder. His numbers are down just a hair on the inner third, which is certainly understandable given his new propensity to rip the ball the other way, but that’s really all I could find. The guy is just plain hitting the ball harder, and I’m not prepared to conclude that it all comes down to his swing decisions.
That brings us to our two tidy narratives. The first is something Adam Berry described somewhat bluntly on the Ballpark Dimensions Podcast. “He was openly not really looking into scouting reports,” Berry told Mike Petriello. “He would ask the hitting coach or the manager, whoever ‘What’s this guy’s fastball?’ That’s all he needed to know before he went up for a plate appearance. He even told us last year at one point he didn’t know other pitchers’ names. He knew his fellow Cubans, and he knew Gerrit Cole, and that was it.”
Joe Trezza gave a more nuanced picture at MLB.com. It’s not that Arozarena couldn’t be bothered, Trezza explained, “He eschewed data, preferring to stay in the moment and let his natural ability take over. Sometimes, he told teammates, he didn’t even want to know the opposing pitcher’s name.”
I am definitely willing to believe that more preparation has helped Arozarena. Lest we forget, this wouldn’t be the first time that Arozarena has decided to put in extra work to up his game and done exactly that. Arozarena is still chasing breaking stuff at almost exactly the same rate, but he is laying off more four-seamers above the zone and offspeed stuff below it. That could be due to having a better idea of how pitchers are attacking him. At the very least, it’s safe to say that incorporating new information into his gameplan hasn’t hurt.
The other thing that could tie our story up with a bow is that Arozarena has made some significant changes to his swing. Last year his stance was extremely upright. This year, he’s crouching a bit more, as he did in 2020. Last year, his hands were up above his ear and he kept his back elbow up, with his bat at a much flatter angle. This year, he’s lowered his hands to shoulder height, with his elbow less elevated and his bat nearly vertical. All of that is completely new. When he goes into his load, he’s rotating his body away from the pitcher less and keeping his shoulders much more level. 2023 is on the left and 2022 is on the right:
Last year, you could pretty much see all of the 56 on Arozarena’s back; this year, you can only see a small part of the six.
Unfortunately, I haven’t been able to find any information about Arozarena’s new stance. He was using it both in spring training and at the World Baseball Classic, so it’s clearly the result of offseason work. To my knowledge, no one has written an article about it. Andrea of Scout Girl Report was the only person I found who’s mentioned it on Twitter.
I don’t know whether Arozarena made these changes on his own, with outside coaches, or with Tampa Bay’s coaching staff, and I haven’t been able to track down a quote about what he hopes they’ll do for his swing. I assume that the desired effect of all these adjustments — deeper crouch, lower hands, less rotation pre-swing — is to make him quicker, starting out with the various parts of his body closer to where they need to be when he begins his swing. Shortening up in this way clearly hasn’t hurt his power. He even set a career exit velocity record last week by hitting a Levi Stoudt four-seamer 114.3 mph. It could also be that lowering his hands and staying more level were changes intended to help him elevate the ball, in which case they have been a soaring success.
So this is where I’m going to leave you. Randy Arozarena is off to a great start. He’s got a new swing. He’s studying scouting reports. He’s chasing less. Through some combination of these factors, he’s elevating the baseball, using the whole field, and hitting it very, very hard. Maybe that’s all we need to know.
Mason Montgomery is the highest-ranked left-hander in the Tampa Bay Rays’ pitching pipeline. No. 7 overall and with a 45+ FV, the 2021 sixth-round pick out of Texas Tech University is coming off his first full professional season, in which he logged a 2.10 ERA with 171 strikeouts in 124 innings between High-A Bowling Green and Double-A Montgomery. Back with the Biscuits to start the current campaign, the 22-year-old Austin native has a 3.38 ERA to go with 16 strikeouts in 13.1 innings.
Deception and ride are among the southpaw’s attributes. As our lead prospect analyst Eric Longenhagen wrote earlier this year, “His glove hand plays the role of the magician’s assistant, flying above Montgomery’s head and toward the hitter when, suddenly, the baseball appears… with a nearly perfect north/south arm slot, imparting the look of rise on his fastball.”
Montgomery discussed his M.O. on the mound, which includes aggressively pumping heaters down the middle, during spring training.
———
David Laurila: What is your approach on the mound? How do you get guys out?
Mason Montgomery: “Man, I think my go-to is just my fastball. It’s kind of got that carry to it, and I usually go to it as my finishing pitch. Sometimes I’ll go slider, too. But really, I just work ahead with the heater and then if I feel like they’re on that, I’ll throw some offspeed over the plate, either my slider or my changeup. That’s my full repertoire: four-seam, slider, and changeup.”
Laurila: How many inches of ride do you get on your four-seamer?
Montgomery: “It changes. At my best, I’ll get consistently 20, maybe 22. Sometimes it will be 17 to 19. So it just depends on the day. Some days I get behind it a little better than I do on others.” Read the rest of this entry »

Let’s dive right into a few incremental changes to the Top 100 prospects list, as well as a couple of non-Top 100 additions.
Cardinals lefty Matthew Liberatore has had a velo spike — he’s frequently reaching back for 96 and 97 when he wants, and his fastball is averaging 94.5 mph. That’s up about a tick and a half from his average in 2022, when he ran an ERA well north of 5.00 across about 150 combined innings split mostly between Triple-A and seven big league starts. Libby has had frequent enough velocity fluctuations during his time as a prospect to anticipate it will be a thing he deals with throughout his career, but his repertoire depth and the long-haul projection for his command will enable him to compete even when he doesn’t have his peak stuff. That’s largely why he was kept on the Top 100 this past offseason even though he had a poor 2022.
His FV isn’t changing in light of the spike (again, it’s fair to bet Liberatore’s peak velo will continue to yo-yo), but his report has been updated and he’s sliding up about 20 spots, from the very back of the list (where he sat with other bounce-back candidates) into the part of it that includes the other major league ready fourth starters. He’s probably better than Jake Woodford is right now, but St. Louis would be burning Woodford’s last option to swap them one-for-one. Woodford was effective in relief last year and could shift into that role again while a current ‘pen occupant is sent down instead, but the Cardinals don’t have an obvious candidate for that, as their big league relievers are largely either pitching well or are out of options.
