Shane Baz features a five-pitch mix: a four-seam fastball and a knuckle curve being the most prominent in terms of usage. The Baltimore Orioles right-hander also throws a cutter, a curveball, and a changeup. And then there is the offering that reluctantly remains in his back pocket. Baz would love to one day unleash his knuckleball on major-league hitters.

“I threw one when I was a kid, up until I was probably 13 or 14,” explained Baz, who was a big Tim Wakefield fan while growing up in Tomball, Texas. “It was my only off-speed pitch up until then — I was just fastball/knuckleball — so I’ve got a lot of experience with it. I actually try to throw it in every bullpen [session]. I’ll definitely get it into a game, eventually. I just have to convince [pitching coach Drew] French to let me throw it. Maybe next spring training I’ll be able to mix some in and show him what it looks like in a game. I mean, it’s pretty good.”

Baz went on to say that that he threw his pet pitch with a three-finger grip — “fingers on the horseshoe, right by the label” — in his younger days, but once his hands got bigger he went to “the traditional two-finger knuckleball.” And while he basically stopped throwing it in games once he matured and developed more pitches, he’s never lost his affinity for baseball’s butterfly.

At 96.1 mph, Baz’s four-seamer is above average for velocity, but while extra oomph is advantageous for heaters, that isn’t the case for low-spin floaters.

“I can get it up to about 80, but those aren’t as good,” Baz said. “I think it’s best when it’s like 70 to 75. That’s when I have the best control of it and can keep the spin really low. When I’m trying to throw it hard, it starts spinning more and not having as much knuckle effect.”

His overall understanding of the pitch is impressive, and that includes spin properties. Read the rest of this entry »

Below is an analysis of the prospects in the farm system of the San Francisco Giants. Scouting reports were compiled with information provided by industry sources as well as my own observations. This is the sixth year we’re delineating between two anticipated relief roles, the abbreviations for which you’ll see in the “position” column below: MIRP for multi-inning relief pitchers, and SIRP for single-inning relief pitchers. The ETAs listed generally correspond to the year a player has to be added to the 40-man roster to avoid being made eligible for the Rule 5 draft. Manual adjustments are made where they seem appropriate, but we use that as a rule of thumb.

A quick overview of what FV (Future Value) means can be found here. A much deeper overview can be found here.

All of the ranked prospects below also appear on The Board, a resource the site offers featuring sortable scouting information for every organization. It has more details (and updated TrackMan data from various sources) than this article and integrates every team’s list so readers can compare prospects across farm systems. It can be found here.

It has been a good year for walks. Whatever you want to attribute it to – and trust me, I’ve done a lot of attributing – batters are drawing free passes more frequently than they have for a long time. Well, most batters. The San Francisco Giants didn’t get the memo. As a squad, the Giants have walked only 5.8% of the time this year. That’s last in baseball by a mile. The gap between them and the 29th-place Rockies is as large as the gap between the Rockies and the league average. What gives?

My investigation started with the 2025 Giants. Walk rate is a stable statistic on the whole. If you walk a lot in one year, you’re likely to walk a lot the next year. But the Giants were no slouches when it came to taking a free base in 2025. In fact, they had one of the highest team walk rates in baseball – 9.2%, fourth in the majors. In the second half of the year, they walked 8.7% of the time. The 10 Giants who batted most frequently had a combined 9.6% walk rate. Four of those players are no longer on the team, but they were actually hurting the average – the six remaining Giants who batted most frequently in 2025 posted an aggregate 10.2% walk rate.

Let’s start, then, with those six players:

As Keanu Reeves memorably put it: Whoa. These six have taken 61.5% of the Giants’ plate appearances this year. If they were walking at the clip they did last year, that would add a whopping three percentage points to the team’s overall walk rate, placing San Francisco squarely in the middle of the pack instead of historically low.

Welcome to another edition of Five Things I Liked (Or Didn’t Like) This Week in Baseball. In keeping with the increasingly lenient definition of “this week” that I’ve been using of late, we’ve got stuff from all throughout May in this column. May is a great time to watch baseball. (It’s always a great time to watch baseball, but May is particularly good.) The weather is heating up. Ballparks are swelling with the start of summer crowds. Tarps are coming off. So please join me on a trip through the league, from fun teams to watch to nifty little plays. And as always, thanks to Zach Lowe of The Ringer for the inspiration.

1. The Go-Go Nats
Nationals fans have endured seven years in the wilderness since the team’s 2019 title. Washington’s season-high win total in that span was 71 (2023 and 2024). This year’s team is finally playing around .500 ball, though our projections think the Nats will end up right around that 71-win high-water mark again. (We have them down for 74 at the moment.) But while the winning hasn’t quite come back yet, the fun has.

This year, the Nationals are dominating on offense. They’re leading the majors in scoring by a mile, averaging an enormous 5.49 runs per game. They’ve hit the most doubles in baseball – in fact, they have the most extra-base hits in baseball. They’re top 10 in on-base percentage, top five in slugging, and top five in stolen bases. They’re first in overall baserunning value. They’re third in BaseRuns-projected scoring. This isn’t smoke and mirrors. Read the rest of this entry »

In his first three seasons, Patrick Bailey carved a niche as one of the game’s top defensive catchers, dominating the Statcast defensive leaderboards and winning two Gold Gloves. The development of his offense has lagged, however, and with the Giants struggling to score runs and sporting one of the majors’ worst records, they’ve decide they can live without Bailey’s glovework. On Saturday, they traded the 27-year-old backstop to the Guardians for 23-year-old lefty pitching prospect Matt “Tugboat” Wilkinson and a Competitive Balance pick in the upcoming draft.

This is the second season in a row that president of baseball operations Buster Posey has shaken up San Francisco’s roster with an early-season trade; last year, it was the mid-June acquisition of slugger Rafael Devers in a blockbuster with Boston. You don’t have to squint too hard to accept that both trades were aimed at upgrading moribund offenses, but when the Giants dealt for Devers, they were 11 games above .500 (41-30), one game behind the Dodgers in the NL West. They felt they’d landed the offensive cornerstone that had eluded them after unsuccessful pursuits of Aaron Judge and Shohei Ohtani, a player who could help them return to the postseason for the first time since 2021. This time around, they entered the day of the trade 15-23, last in the division, and the move appears far more tilted toward the future, as Wilkinson has just gotten his feet wet in Double-A and the draft pick won’t make an immediate impact.

If this trade had occurred just prior to the deadline (August 3 this year), it might have been characterized as a white flag, part of a larger selloff. To these eyes, it’s a shakeup that at worst smacks of panic and at best places a lot of faith that Posey — a likely Hall of Fame catcher who has yet to show similar prowess as an executive — has found a diamond or two in the rough with his two recent catching acquisitions: Jesus Rodriguez, who came from the Yankees in last year’s Camilo Doval trade, and Daniel Susac, who was flipped by the Twins in December after being plucked from the A’s as a Rule 5 pick. Both are 24 years old and have fewer than 10 games of major league experience, with Susac, who turns 25 on May 14, currently on a rehab assignment after being sidelined by neuritis in his right elbow. Eric Haase, a 33-year-old backstop who hit his way out of a starting job in Detroit in 2023, started in Saturday’s 13-3 drubbing by the Pirates — San Francisco’s ninth loss in 11 games — while Rodriguez started Sunday’s 7-6 win, which lifted the team’s record to 16-24, still third worst in the NL.

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.

1. Ricochets
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:
