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 »

Apparently Luis Arraez is good at defense now. This took me by surprise, and perhaps it also took you by surprise, or perhaps it is at least taking you by surprise in this exact second, as you ingest this blog. Because if there’s one thing you know about Luis Arraez, it’s probably… well, it’s that he is incredible at contacting the baseball with a bat. But if there’s a second thing you know about Luis Arraez, it’s that he is not very good at defense.

This fact is a key totem in the still-raging Arraez Wars of the 2020s. Those who like baseball played the old-fashioned way insist that he is an MVP-level talent, enraging most contemporary baseball fans who understand that singles are only so valuable, especially for a guy who can’t run well or hold down a defensive position.

When Arraez signed with the Giants this offseason under the condition that he would only play second base, the universal reaction was something like, “OK, well, good luck with that.” Such pessimism was warranted. In 2024 — his age-27 season! — he graded out as -7 outs above average at second base in just 42 games played there; given a full season, he would’ve easily been the sport’s worst defender at the position. In 2025, the Padres punted him down the defensive spectrum to first base. But even at first, Arraez looked nearly unplayable, racking up another -7 OAA at the notoriously easy position. (It’s not that hard, tell ’em Wash, etc.) Those lacking the range to play first base often find themselves consigned to designated hitterdom sooner rather than later.

Not so fast, Arraez said. On February 13, Susan Slusser of the San Francisco Chronicle published a story with a shocking lede: “Luis Arráez’s fielding at second base is already vastly improved, at least according to San Francisco Giants infield coach Ron Washington, and Arráez agrees.” Slusser cited Arraez’s hard work over the offseason as the catalyst.

It’s not obvious why Landen Roupp is good, but it’s probably time to find out.

Roupp’s 2.54 xERA is seventh among qualified starting pitchers. He’s striking out batters, getting groundballs, and working deep into games. He’s tied for 15th in the majors with 0.9 WAR. That’s about 70% of what he was projected for by FanGraphs Depth Charts in the preseason. It’s one of the most surprising performances of April.

Most pitchers “get good” because they miss bats, or attack the zone, or both. That doesn’t apply to Roupp this year. His 25.1% whiff rate is about the median among qualified pitchers, and his 37.1% zone rate is bottom five. Frankly, he doesn’t throw a ton of strikes.

The underlying “stuff” metrics aren’t any more impressive.

Roupp doesn’t throw particularly hard, or display outlier movement, or place near the top of any leaderboard I know to check. And yet, he excels. Where is all that value coming from? Read the rest of this entry »

I’ve been fascinated by Caleb Kilian for quite a while. Since 2021, to be precise, when he put together a dazzling 80 innings of minor league work for the Giants and then got traded to the Cubs in a deal for Kris Bryant. At the time, Kilian was essentially a lottery ticket, an eighth-round pick in 2019 who was old for his level. But man, those 80 innings were just the kind of innings I like – great command fueling both a pristine walk rate and a ton of strikeouts. I filed a mental note to keep my eye on him: Low-stuff high-command guys sometimes pop with a change of scenery, at least in my head.

That didn’t transpire in Chicago. Kilian got a cup of coffee in 2022 and another one in 2023, but his walk rate ballooned as he reached back for more velo against tougher competition, both at Triple-A and in the majors. And then a shoulder strain cost him half of the 2024 season. He returned for 2025 and found himself in minor league limbo as he transitioned to the bullpen; the Cubs released and then re-signed him due to roster considerations, and he hit minor league free agency after the season. He signed a minor league deal with the Giants over the winter, now as a full-fledged reliever. And that’s where the meat of this article begins.

The early book on Kilian was a standard one: plus command, wide arsenal, but no true out pitch and below-average velocity. In his time with the Cubs, however, that changed. By 2024, Kilian was touching 100 at times, but we graded his command as only average. In other words, his results and scouting report matched: He was throwing harder, but it wasn’t working better.

Welcome to a new season of Five Things I Liked (Or Didn’t Like) In Baseball This Week. After a slow, veteran-who-signed-late-this-spring style warmup to the year, it’s time for another dive into the little details that catch my eye each week. It’s the perfect time of year for it. Beautiful weather, early-season optimism, overheard conversations about who should bat third and who’s a bum – it all fuses together to make this one of my favorite parts of the baseball calendar. And even though the WBC whetted my appetite for the spectacular somewhat, there’s really no replacing major league games for the sheer variety of entertainment. I’m sure that Zach Lowe of The Ringer, whose old NBA column format I’ve borrowed, would say the same thing about the basketball regular season. Let’s talk baseball.

If you share my baseball consumption habits, it might seem like every weekday offers a Royals game, a Guardians game, or a Royals-Guardians game. And I love it! I’ll take any excuse to watch Maikel Garcia continue his ascent from contact hitter to do-it-all superstar, a kind of modern-day José Ramírez. And I get to watch the actual José Ramírez too? And Bobby Witt Jr.? And Steven Kwan, Vinnie Pasquantino, Bo Naylor, and old favorite Michael Wacha? Both of these teams are sneaky fun, and their series this week didn’t disappoint. Witt might be having a slow start on offense, but he’s still a defensive genius:

Lots of shortstops – pretty much every other shortstop, even – would get only one out, somewhere, on that play. But two?! Ludicrous. When Garcia’s lunging attempt caromed toward Witt, he turned from interested observer to protagonist so smoothly that it looked like he was planning on doing it the whole time. It started with his feet. Instead of charging the ricochet, Witt timed his steps to hop to a stop and get his body in as good a throwing position as he could:

On Saturday, in the third inning of their game against the Yankees at Oracle Park, the Giants scored a run. Normally, this wouldn’t rate as particularly noteworthy, but that was one more run than they’d scored in the previous 20 innings while dropping their first two games of the 2026 season. As far as their season-opening series went, it was a one-shot deal, as they didn’t score again.

Indeed, the Giants were utterly stifled by the Yankees over those three games. On Wednesday night, when the two teams had the stage to themselves for a nationally televised game on Netflix (don’t get me started about that production), Max Fried and three relievers held the Giants to three hits, all singles, in a 7-0 loss; the Giants reached base just four other times in that one via two walks, a hit-by-pitch, and an error by shortstop Jose Caballero. On Friday afternoon, following a day off, Cam Schlittler and four relievers limited the Giants to one hit in a 3-0 defeat, a second-inning double by Heliot Ramos; in that one, the Giants additionally reached base only twice, on walks in the seventh and ninth innings.

With that, the Giants and Yankees made some history. Those double zeroes marked the first time in the Giants’ 144-year history that they were shut out in their first two games of the season. It had happened just once to any other team within the past decade, the 2023 Royals (at the hands of the Twins). For the Yankees, it was the first time since their 1903 inception that they shut out opponents over their first two games. What’s more, according to the Associated Press it was the first time that any team was shut out and held to a combined total of five hits or fewer over a season’s first two games.

Last week, we got a mailbag question from James, whose glimpses of Luis Arraez during the World Baseball Classic left him looking for one weird trick to vault the three-time batting champion back up to his previous heights. I had so much fun answering the question that its word count moved it out of mailbag territory (non-Jay Jaffe division, anyway) and into regular article territory. The question was on the longer side, but here’s an abridged version:

If [Arraez] could wear a ribbon on his wrist to deter a bad hitting habit, would he be able to avoid something that drags him down?

My first idea was swinging on 3-1 counts… If he spit on 3-1 pitches habitually, until opposing pitchers caught on, what percentage of them would have landed him on first? What impact would that have on his OPS & WAR, and how would that impact his value and employability?

Could there be other commonplace opportunities that may be similarly exploited?

I realize James is asking for a more specific answer here, but I want to start with the overview, because at this point, I think people may have forgotten that once upon a time, Arraez actually had great plate discipline. From 2019 to 2022 he ran a 24% chase rate and a 9% walk rate. That walk rate was 5% higher than the league average. From 2023 to 2025, he had a 34% chase rate and a 4% walk rate. That walk rate is now a staggering 45% below the league average! Over the same period, Arraez’s swing rate on pitches inside the zone fell from 65% to 62%. He wasn’t just chasing more; he was making worse swing decisions all around. That’s a lot of shifts in the wrong direction, and even though Arraez also cut his strikeout rate nearly in half, his wRC+ dropped from 123 to 109. Read the rest of this entry »

We did it everyone! We made it through the long offseason. Regular season baseball is back, and it has already delivered the goods. I attended Mets-Pirates at Citi Field on Opening Day to witness the highly anticipated pitching matchup between reigning NL Cy Young winner Paul Skenes and new New York ace Freddy Peralta. Naturally, Skenes had the worst game of his career thus far, failing to make it through the first inning, and Peralta didn’t pitch well either. The two teams combined for 18 runs in the 8 1/2 innings of play. I wrote about the Skenes start, the two defensive blunders by Oneil Cruz in center field that contributed to Pittsburgh’s first-inning fiasco, and the lineup’s surprisingly strong showing. You can read that here.

Because I was covering that contest, I didn’t get a chance to watch any of the other early games and saw only a portion of the later ones. That means I missed White Sox catcher Edgar Quero successfully challenge three ball calls in the first two innings before finally getting one wrong in the sixth inning. In that same game, which the Brewers won 14-2, Jacob Misiorowski struck out 11 Chicago batters. I also didn’t catch the pitcher’s duel between Orioles lefty Trevor Rogers and Twins righty Joe Ryan; Baltimore won, 2-1, and Adley Rutschman, not to be confused with Badley, went 2-for-4, though Tyler O’Neill’s Opening Day home run streak was snapped at six. In the later afternoon games, the Cardinals scored eight runs in the bottom of the sixth inning to secure a comeback win over the Rays, after allowing Tampa Bay to plate six runs in the top of the frame. JJ Wetherholt, who went 1-for-4 with a home run and two RBI in that game, was one of a number of prospects who shined in their big league debuts. Kevin McGonigle had four hits in the Tigers’ 8-2 win over the Padres, and Justin Crawford went 2-for-4 in the Phillies’ win over the Rangers. I actually got to see Mets right fielder Carson Benge blast his first homer, this after a dead bird had fallen in front of him in right field. It wasn’t technically his first major league game because he debuted in the postseason last year, but Cleveland’s Chase DeLauter bopped two home runs in a 6-4 win over the Mariners.

I ran through all those games up top because that’s the last we’ll be covering the Opening Day action in this week’s mailbag. Instead, we’ll be answering your questions about Matt McLain’s strong spring, Aaron Judge’s low squared-up rate, players who might benefit the most from ABS, and Tony Vitello.

Dean Kremer has been a staple of the Orioles rotation in recent years. Even while missing significant time due to injuries in a couple of seasons, he’s made more starts than any other Baltimore pitcher since the beginning of 2022, a span that encompasses both the division-winning Orioles from ’23 and last year’s basement dwellers. Yet this past weekend, Kremer was optioned to the team’s minor league camp, the odd man out in a rotation battle. He’s not the only familiar name among those slated to start the season in the minors due to such decisions.

Opening Day is full of fanfare and so often freighted with meaning, but it’s still just one day on the baseball calendar; the decisions regarding who gets to be there (and who doesn’t) don’t actually define the season. Still, unless they’re recalled to replace injured players — which is hardly out of the question — optioned position players need to remain in the minors for 10 days and pitchers for 15 days, counting from March 25 (Opening Day for the Giants and Yankees). In other words, they’ll be eligible to return on April 4 or April 9. Beyond that, circumstances change as the season progresses, and rosters are in a constant state of flux.

Kremer stands out because he’s fully established himself in the majors, while the other high-profile decisions I’ve highlighted below involve players who are or were recently considered top prospects. They’re all headed to Triple-A, and I expect them to stay past the aforementioned dates, but they’re notable because they’re still expected to play substantial roles in 2026. The players are listed alphabetically. Read the rest of this entry »

Trey Yesavage profiles as a strong Rookie of the Year candidate, but he won’t have a chance to begin building his case in the near term. The 22-year-old Toronto Blue Jays right-hander landed on the injured list due to shoulder impingement and won’t be ready when the season gets underway later this week. His return is expected to come sooner rather than later — fingers are crossed throughout Canada — but for now, Yesavage is on the shelf.

Five months ago he was turning heads in the World Series. With just six MLB outings under his belt — three in the regular season, and three across the ALDS and ALCS — Yesavage bedeviled LA batters with an array of high-riding heaters and diving splitters. He was especially dominant in Game 5, fanning a dozen Dodgers while allowing three baserunners and a lone run over seven frames.

His meteoric rise and eye-popping postseason performances raised his public persona, but the Pottstown, Pennsylvania native hasn’t otherwise changed since being drafted 22nd overall in 2024 out of East Carolina University. He’s still polite and unassuming, and his overpowering arsenal has remained in place.

“I’m pretty much the same dude,” Yesavage told me at Blue Jays camp last week. “The pitches are the same. The velocity and movement are the same. I also don’t look at [the metrics] all that much. Whenever Trackman is up on the board, all I really look at is the vert on my heater, and the velo. The only questions I’ll ask my pitching coach are to make sure that my most-used pitch is in line.”

That would be his four-seam fastball, which averaged 94.7 mph and 19.5 inches of induced vertical break across his smattering of regular season outings. Thrown at a 45.2% clip, the offering was augmenting by a slider (28.4%) and a splitter (26.4%), the last of those offerings being the righty’s most lethal weapon. A quintessential complement to his well-elevated heaters, Yesavage’s splitter induced a 57.1% whiff rate and a .111 BAA against big-league hitters.

He began tinkering with his signature pitch in the middle of his three collegiate seasons, but it wasn’t until his draft year that the efforts bore fruit. Read the rest of this entry »
