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 »

The Rays continue to play phenomenal baseball. While their 14-game home winning streak came to an end on Tuesday night, they have won six of their last seven and boast what is easily the best run differential in the sport. Their average margin of victory is 3.7 runs, which is more than the Tigers, Marlins, and Royals are scoring per game. As if all that weren’t enough, Tampa Bay is only getting stronger. Zach Eflin returned from a back injury on Sunday and twirled five innings of one-run ball. Tyler Glasnow threw his first simulated game on Monday, a critical step in his rehab process as he works to rejoin the rotation. Meanwhile, top prospect Taj Bradley is waiting in the wings after making a fantastic big league debut.

For all that good stuff, however, the Rays have also been dealt a significant blow. On April 13 against the Red Sox, Jeffrey Springs looked down at his elbow after throwing a pitch; it would turn out to be his last of the 2023 campaign. Coincidentally, the Rays would lose their first game of the year the following day. Springs landed on the injured list with a diagnosis of ulnar neuritis but was later revealed to have torn his UCL; he underwent Tommy John surgery earlier this week to repair the ligament, leaving the Rays to go the rest of the way without the player who could have been their biggest success story. That’s a bold claim to make about a man on the same team as Yandy Díaz and Randy Arozarena, but that’s just how well Springs was pitching. Read the rest of this entry »

Let’s start this article with a bold claim: Wander Franco’s first two seasons in the majors were a disappointment. That’s a startling assertion, even if it might not seem that way at first. Franco hit .282/.337/.439, good for a 121 wRC+, while playing league average defense at shortstop; he was 20 years old for the first of those seasons. He played at a 4.3 WAR per 600 PA clip, which the FanGraphs glossary helpfully notes is an All-Star level. That’s all true. For the best prospect of the past decade, though, it still feels like a letdown.

The real thing that has betrayed Franco is playing time. First for nebulous service time reasons, then due to injury, his first two seasons in the majors were both as brief as they were scintillating. He appeared in 70 games in 2021 and 83 in 2022. His counting stats weren’t exactly imposing: 13 homers, 10 steals, and a mere 72 RBI if you’re playing fantasy baseball. I acknowledge that considering that performance a disappointment is grading on a curve, but when you’re as good and hyped as Franco is, that comes with the territory.

Now that we’ve gotten that out of the way, it’s time for the good news: that perception is as stale as the sourdough I bought last Wednesday and didn’t finish (hey, there’s a good bagel shop nearby, and I’m only human). Franco isn’t a young up-and-comer this year. He’s a bona fide star, one of the best hitters in baseball so far and the best player on the best team. It’s only a matter of time before your marginally-baseball-following friends start asking you if you’ve heard about this Wander guy. So allow me to present a gift to you as a baseball fan who wants to sound smart to their friends, a guide to why Franco is one of the best players in baseball and what he changed to get there.

Billy Wagner was the club’s closer when Craig Kimbrel joined the Atlanta Braves in 2010. Thirty-nine years old by season’s end, Wagner logged the last 37 of his 422 career saves, and he was as dominant as ever while doing so. Over 69-and-a-third innings, the left-hander fanned 104 batters while allowing just 38 hits.

Kimbrel, who was just 21 years old when he debuted that May, was every bit as overpowering. In 21 appearances comprising 20-and-two-thirds innings, the rookie right-hander fanned 40 batters while allowing just nine hits. Along the way, he recorded the first of what is now 395 saves.

I’ve had a Hall of Fame vote for three years, and in each of them I’ve put a checkmark next to Wagner’s name. This coming winter, I plan to do so again in what will be his penultimate year on the ballot (assuming he doesn’t get voted in; Wagner received 68% of support in his last go-round).

Kimbrel will soon celebrate his 35th birthday, and while the end of his career is fast approaching, he’s still pitching. Will he likewise be getting my vote once his name appears on the ballot? And what about Kenley Jansen? Still going strong at age 35, he’s also got 395 saves, tying him with Kimbrel for seventh on the all-time list, directly behind Wagner.

Let’s compare some of their numbers:

Wagner: 422 saves, WPA 28.40, 187 ERA+, 2.73 FIP, 6.0 H/9, 11.9 K/9.
Kimbrel: 395 saves, WPA 22.99, 174 ERA+, 2.38 FIP, 5.2 H/9, 14.3 K/9.
Jansen: 395 saves, WPA 24.72, 161 ERA+, 2.44 FIP, 5.8 H/9. 13.0 K/9. Read the rest of this entry »

For half of Thursday’s game against Boston, it seemed like the good times had finally stopped rolling for the Tampa Bay Rays. The hitherto unhittable Jeffrey Springs left the game with ulnar neuritis—nerve irritation in his elbow, but it’s scarier when you say it like the name of the chancellor of a minor Star Trek world. Corey Kluber had held Tampa Bay’s vaunted offense to just one run through four innings.

Then the Rays burst out for seven runs as if out of nowhere. The highlight of the inning was probably Manuel Margot’s pinch-hit RBI bunt. Bunting for a hit with two outs and the bases loaded is the kind of thing you do when a mystical hooded figure grants you the power of telekinesis and you want to see if it’s real or you’re being pranked. That’s just how things are going for Tampa Bay right now.

But the biggest hit of the inning, according to WPA, was Brandon Lowe’s seeing-eye single three batters prior, which tied the game with two outs. If the Rays are actually going to continue on as the best team in baseball, Lowe is one of their most important players. Read the rest of this entry »

Evan Reifert has one of the best sliders in the minors. In the words of our lead prospect analyst Eric Longenhagen, “the pitch is incredible, a low-80s knee-buckler that he throws about as much as his fastball.” Moreover, the numbers are as good as the observations. As Eric noted when profiling the 23-year-old right-hander for our 2023 Tampa Bay Rays Top Prospects list, Reifert’s slider “generated the top whiff rate of any pitch in the 2022 minors at a whopping 70%.”

Overall, the numbers were that of a work-in-progress. Pitching between three levels — the majority of his 31 relief outings came with High-A Bowling Green — Reifert logged a 4.58 ERA and issued 20 free passes over 37.1 innings. He was also overpowering; thanks largely to his signature pitch, the Wilton, Iowa native fanned 62 batters.

Assigned to the Arizona Fall League’s Mesa Solar Sox to build on what had been an injury-interrupted campaign, the erstwhile Milwaukee Brewers prospect — Tampa Bay acquired him in exchange for Mike Brosseau in November 2021 — proceeded to put up eye-popping numbers. In eight AFL appearances comprising 11.1 innings, Reifert registered 25 punchouts and allowed just one hit.

Reifert, who is currently on the injured list at Double-A Montgomery, discussed his wipeout slider during spring training.

———

David Laurila: You have a plus-plus slider. What is the story behind it?

Evan Reifort: “I was pretty young. I was growing up playing travel ball, and I have a great uncle who was a really good pitcher back home in Iowa. His name is Ron Reifert.”

Laurila: Did your great uncle play pro ball?

Reifert: “He did not. Unfortunately, polio kind of got to him — I believe it was polio — so he was unable to go on to play pro ball, but he pitched at the University of Iowa and was really good. That’s kind of where I started learning how to throw a slider, from him. I was probably 10 or 12, and from there it’s morphed into the pitch it is today. I found a grip that I liked and have even modified it since then. It’s definitely gotten harder and sharper over the years. But yeah, all I really do is rip it and let it do its thing.” Read the rest of this entry »

Friday night’s game at Tropicana Field featured a rare sight: the Rays trailing a team by a 1–0 margin. It was a blink-and-you-missed it moment, with a run in the top of the second inning putting Tampa Bay behind for the first time since Tuesday night, and just the second time all season. But it didn’t last long: on the first pitch of the second inning, Harold Ramirez hit a Ken Waldichuk offering for a solo homer into the right field corner, kicking off a six-run inning that also featured a grand slam by Isaac Paredes. The Rays never looked back, beating the A’s, 9–5, on Friday and then 11–0 on both Saturday and Sunday to run their record to 9–0.

It’s an understatement to say that the Rays are off to the best start in franchise history (their previous record for season-opening wins was three) or the best of any team this year. By consecutive victories to open a season, they’re off to the best start in 20 years, and by run differential, they’re doing some things not seen in the majors since the late 19th century — and some never seen before.

David Ross was 38 years old and still strapping on the tools of ignorance when he was featured here at FanGraphs in February 2016. The title of the piece was David Ross: Future Big League Manager, and as many in the industry had suggested it would, that supposition soon came to fruition. The longtime catcher is currently embarking on what will be his fourth season at the helm of the Chicago Cubs. I recently asked Ross how he approaches the job philosophically now that he’s firmly in the trenches.

“My style — the way I approach being a manager — is leadership and direction, but I’m also still a player at heart,” Ross told me. “I understand what these guys are going through, competing for jobs and different roles. Communicating through that as a former player, someone who experienced it, I can relate to them. I try to keep a player’s mindset as part of my decision-making.”

Jed Hoyer was the club’s General Manager when the Cubs hired Ross following the 2019 season. I asked the now President of Baseball Operations about the process that informed that decision. Read the rest of this entry »
