Yandy Díaz was in the news last week when he recorded his 1,000 career hit, making him the 20th Cuban-born MLB player to reach that milestone. The plaudits he received were well deserved, and they were also relatively uncommon. Playing in a lower-profile market, the Tampa Bay Rays stalwart flies under the national radar. Be honest. Outside of when he captured the American League batting title with a .330 average in 2023, when was the last time you paid more than a modicum of attention to the player who is arguably the top hitter in Rays franchise history?

You’re excused if you weren’t aware of just how good Díaz’s numbers are. Now in his eighth season with Tampa Bay after parts of two in Cleveland, he boasts a 133 wRC+ with the Rays, the highest in team annals among hitters with at least 1,000 plate appearances. Over 3,627 plate appearances with his current club, the 34-year-old corner infielder/DH has a .291/.373/.447 slash line and 104 home runs.

Díaz was admirably humble when asked about his milestone the following day.

“I never thought I’d get to 500, let alone 1,000,” he told reporters. “When I signed with Cleveland, I honestly never really thought I was going to get to the major league team. I thought, yeah, I was going to be a professional, but maybe I was going to get cut — specifically because it’s a different style of play over in Cuba. I thank God that I made the team and have been able to do it for so long.”

I asked the Sagua la Grande native how much he’s changed — and how much he really hasn’t changed — since coming stateside to play professionally in 2013. Read the rest of this entry »

Spencer Arrighetti has twice been featured here at FanGraphs in standalone fashion, yours truly having interviewed the 26-year-old Houston Astros right-hander in April and August of his 2024 rookie season. On both occasions, he displayed an impressive knowledge of pitching analytics, as well as a thoughtful overall approach to his craft.

Our third conversation ended up focusing on his curveball. Arrighetti has been throwing the pitch at 31.4% clip this season, and not only has it been his most-used offering, it has been highly effective. As of this writing, it has yielded a .121 batting average and a .151 slugging percentage while eliciting a hefty 50.9% whiff rate. Arrighetti, who took the mound just seven times last season due to a fractured thumb and then right elbow inflammation, has made five starts this year to the tune of a 4-1 record and a 1.88 ERA over 28 2/3 innings. I spoke with him about his curve at Fenway Park earlier this month.

———

David Laurila: You’re throwing a lot more curveballs than in years past. Why is that?

Spencer Arrighetti: “Before I got hurt, it was a top-10 curveball in baseball. That makes me feel confident to throw it to whomever, and at any time in the count. Having a pitch like that goes a long way, especially as a starting pitcher. I’ve just leaned into it a little more this year. In the past, I had the thought process that to get a chase or a whiff on a curveball, you had to set it up with a fastball — something harder in the zone — in order to make a hitter be early on it, or to be off of the shape. I’ve kind of found that there are guys that I can just spam it to. I can throw it as many times as I want, in the zone, out of the zone, and get good results. Read the rest of this entry »

Kai-Wei Teng had a limited repertoire when he signed with the Minnesota Twins out of Taiwan in 2017. The right-hander from Taichung possessed just a fastball and a curveball. A lot has changed since that time. Now 27 years old and pitching for the Houston Astros, Teng attacks hitters with a five-pitch mix that includes a sweeper that is not only hard to hit, it is no fun to be on the receiving end of in catch-play.

“It’s insanely good,” Spencer Arrighetti told me last weekend at Fenway Park. “I throw a sweeper. Lance [McCullers] throws a sweeper. We have a couple of other guys who toy around with it. But Teng’s is incredible. Truly. I played catch with him, and it looks like a fastball for 48 feet, then takes a 90-degree left turn. Not all sweepers are created equal. Some of them are a little loopier and bigger, but his is 85 mph. I mean, it’s gross. It really is a great pitch.”

The numbers back that up. Teng has relied on his most-used offering 36.3% of the time this season to the tune of a .118 BAA, a .118 SLG, and a 27.9% whiff rate. His other numbers are impressive, as well. Over 14 appearances, Teng has a 2.35 ERA, a 3.83 FIP, and a 24.7% strikeout rate over 23 innings.

I asked Teng for the story behind his best weapon. Read the rest of this entry »

Not all splitters are the same. Hybrids are common — think “splinkers” and split-changes — hence the variations seen in both velocity and movement. The human element is also at play. Regardless of the grip, one pitcher’s split isn’t necessarily going to behave exactly like another pitcher’s. From finger dexterity to arm action, and whatever else might factor in, differences are inevitable.

And then there is spin. Per Statcast, pitches classified as splitters currently range from 508 rpm (Cade Smith) to 2,105 rpm (Joe Boyle). Fifteen of the 71 pitchers who have thrown a splitter this year (minimum 10 innings pitched) are averaging fewer than 1,000 rpm, with Smith being one of seven under 800 rpm, the others being Logan Gilbert (687), Hunter Barco (689), Mark Leiter Jr. (689), Fernando Cruz (774), and Roki Sasaki (776).

Watching a recent game where a splitter acted almost like a knuckleball got me thinking about low spin, and what better way to learn about the subject than talking to someone in the know? Previously with Driveline and Prime Sports Performance, Spencer Medick is now the pitching coach for the Scranton/Wilkes-Barre RoughRiders, the Triple-A affiliate of the New York Yankees.

I began by asking Medick if anyone on his current club throws a splitter. Read the rest of this entry »

Jonathon Long has logged a shiny 137 wRC+ since he was selected in the ninth round of the 2023 draft out of Long Beach State. How bright of a future he has is a question not easily answered. Ranked 17th on our recently released 2026 Cubs Top Prospects list with a 40 FV, the 24-year-old first baseman has a profile that is promising, yet in some ways concerning.

Last season’s numbers were particularly strong. Playing at Triple-A Iowa, Long slashed a robust .305/404/.479 with 20 home runs and a 131 wRC+ over 607 plate appearances, which led to his being honored as the organization’s Minor League Player of the Year. His right-handed bat hasn’t been nearly as productive in the current campaign — a .294/.369/.405 slash line with a pair of round-trippers and a 101 wRC+ over 143 plate appearances — but he nonetheless remains a threat to opposing pitchers. Moreover, he has begun to warm up. Over his last nine games with Iowa, Long is 14-for-40 (.350).

A hyperextended elbow caused the Orange, California native to miss time in spring training, a period that coincided with my annual visit to Cactus League camps. Intrigued by his stat sheet and scouting reports alike, I asked Long if he considers himself more of a power hitter, or more of a contact hitter.

“I’m probably a little bit of both,” replied Long, whose 20.3% strikeout rate and 10.5% walk rate this season are slightly worse than last year’s respective marks of 19.7% and 13.2%. “I don’t like striking out, and I have pretty good exit-velocity numbers. If you combine those, you kind of get a high contact rate and a power hitter.”

Our recent prospect report on Long, put together by Eric Longenhagen and James Fegan, is largely in accord with that self-assessment. Bullish in agreement, it nevertheless came with a caveat: Read the rest of this entry »

When David Morgan was profiled in last year’s rankings of the San Diego Padres’ top prospects, it was pointed out that the 26-year-old right-hander had joined the organization as a non-drafted free agent in 2022. Moreover, he’d barely taken the mound. A two-way player at Hope International University — an NAIA school in Fullerton, California — Morgan had thrown just nine-and-a-third innings. At the time he signed, he was playing for the Portland Pickles in the summer collegiate West Coast League (for which Rob Neyer is the commissioner).

Morgan’s backstory sets him apart him from his MLB brethren, but what about from a pitch-specific standpoint? Are there any differentiating characteristics?

“My ability to pick stuff up and kind of run with it is probably the most unique thing about me,” said Morgan, who made his big-league debut last May and has since logged a 3.41 ERA and a 4.15 FIP over 52 appearances comprising 60-and-two-thirds frames. “Last year, when I had to throw a sinker, it wasn’t really a learning process. It was in-between innings. I came into the dugout, grabbed a new grip, and threw it the next inning.”

The outing, his sixth in the majors, came on June 10 with the Padres holding a commanding late-inning lead against the Los Angeles Dodgers. When Morgan returned to the dugout after working the eighth, pitching coach Ruben Niebla pulled him aside and asked if he’d ever thrown a sinker. The answer was yes and no. Morgan had toyed around with one, but that was about it.

With the game not in doubt — San Diego led 11-1 — Niebla “gave [him] a grip and said to go out and throw it next inning.” Morgan did, the pitch “danced around a little bit,” and the rest is history. By season’s end, he’d thrown his sinker at a 21.5% clip, and this year the usage is up to 34.7%. Read the rest of this entry »

Brant Hurter is a reliable reliever who largely flies under the radar. Since debuting with the Detroit Tigers in August 2024, the 6-foot-6, 250-pound southpaw has fashioned a 2.49 ERA and a 3.41 FIP over 64 appearances comprising 119 1/3 innings. Moreover, he has registered a pair of saves and a 13-4 won-loss record.

He is off to a solid start in the current campaign. Hurter has come out of the ‘pen 11 times and allowed just three earned runs over 11 frames. His outings have been timely. The 2021 seventh-round pick out of Georgia Tech has wins in all three of his decisions.

Befitting his low profile, Hurter wasn’t highly regarded coming out of college, nor was he viewed as a future star while down on the farm. That doesn’t mean our lead prospect analyst didn’t see a big league future. Ranked 17th with a 40 FV on our 2024 Tigers Top Prospects list, Hurter was described by Eric Longenhagen as a pitcher he could “see in an important bulk relief role.” Read the rest of this entry »

Nathan Lukes was 28 years old and in his ninth professional season when he made his MLB debut with the Toronto Blue Jays in 2023. He almost didn’t make it that far. Life down on the farm isn’t exactly a bed of roses, and that was especially true prior to conditions — financial and otherwise — improving via a collective bargaining agreement that essentially coincided with his reaching the bigs. A few years earlier, Lukes almost walked away.

“It’s been a journey,” Lukes said of his path, which began when Cleveland selected him in the seventh round of the 2015 draft out of Cal State Sacramento. “Five games into my career — this was in short-season ball — I broke my hamate and was out for the rest of the year. The next year, I started in Low-A, and halfway through I got traded to Tampa Bay at the deadline. I stayed with the Rays until my minor-league contract was up, then signed here [in November 2021].

“It was getting to the point where it was almost time to think about hanging it up,” continued Lukes, whom the Blue Jays placed on the IL with a hamstring strain prior to yesterday’s game. “But then, in 2023, they put me on the 40-man roster. Pretty much as long I had that 40-man ticket, I was going to keep running with it.”

The now-31-year-old outfielder didn’t feel that he had stalled out developmentally when he pondered calling it a career — “I always felt that I could play in the big leagues” — but he did recognize that there is more to life than baseball. Lukes and his wife had a child in 2021, and as he explained. “Family changes things.” While his financial situation had improved somewhat thanks to minor-league free agency, he was “going to play the 2022 season, and after that, probably just be a dad.”

“You weren’t getting rich,” I said to Lukes in our spring training conversation. “No,” he replied. “I was getting poor. My wife was working at the time, which helped… actually, it didn’t just help, it kept us running. At the lower levels, I was bringing home six thousand dollars a year after taxes, so I was making a thousand dollars a month. The most I ever made on a minor-league contract was $15,000. You can’t really do too much with that.” Read the rest of this entry »

Dan Petry faced 644 different batters across the 1979-1991 seasons, and while he certainly doesn’t remember them all, his level of recollection is impressive. Now 67, the former All-Star right-hander proved as much when he became the latest pitcher-turned-broadcast analyst to tackle one my a matchup-focused career quizzes. As did David Cone, Mark Grant, Mark Gubicza, and Jeff Montgomery — those pieces can be found here, here, here, and here — “Peaches” reached into his personal memory bank to take a stab at answering my questions, and to provide entertaining anecdotes while doing so. Our conversation took place at Fenway Park this past weekend.

I began by asking him which batter he faced the most times.

“It would have to be somebody in the American League East,” replied Petry, who played the bulk of his career with the Detroit Tigers and is now Dan Dickerson’s primary partner in the team’s radio booth. “I’ll say Robin Yount.”

It was indeed Yount, who stepped in against Petry 89 times. I proceeded to ask which player recorded the most hits off him.

“That might be a trick question, because maybe it is Robin Yount,” said Petry, before going with a different answer. “But I think a lot of my answers are going to be George Brett, so I’ll say George Brett.”

He should’ve trusted his initial instinct, because Yount was the answer again. The Hall of Famer logged 24 hits in 83 at-bats against the right-hander, who went 119-93 as a Tiger and 125-104 overall, while tossing 2,080 1/3 innings over 370 big league outings.

“He is a guy who I’ve always, to this day, have so much respect for,” Petry said of the Milwaukee Brewers icon. “I remember when he was just a teenager. At that time [when Yount was in the majors at age 18], I was a teenager also, and thinking about whether I would ever get that opportunity to play, like he was doing. So, just getting to face him was among my most competitive moments.”

How about the batter to whom he surrendered the most home runs? Read the rest of this entry »

Arjun Nimmala has a high ceiling that he is still far away from reaching. No. 2 on our Toronto Blue Jays Top Prospects list, and No. 48 on our Top 100, the 20-year-old shortstop is presently slashing .163/.308/.372 with two home runs and a 94 wRC+ in 52 plate appearances with High-A Vancouver. Last season, he left the yard 13 times while putting up a 92 wRC+ over a full course of games at the same affiliate. But while the production hasn’t been anything to write home about, the potential is clearly there. As Brendan Gawlowski explained in his scouting profile, “We really like the athlete and tools here, and we’re betting the results will follow in time.”

Nimmala’s right-handed stroke projects to produce plus power once he fully matures, and I asked him about it during spring training

“It’s a swing that’s built to do damage,” replied Nimmala, whom the Blue Jays drafted 20th overall in 2023 out of Dover, Florida’s Strawberry Crest High School. “I pride myself in taking good swings. When things are going well, I have a really good idea of the zone and am doing damage to all parts of the field.”

Asked to elaborate, Nimmala said he considers his bat path a plus — “I think it’s been good since high school” — adding that his adjustments since reaching pro ball have mostly been about putting himself in better launch positions. He further explained that he has tweaked his posture and how he lands.

As for reports saying that his swing is a little on the long side, but also quick, he agrees — but only to a point. Read the rest of this entry »
