Landen Roupp leans heavily on his high-spin curveball, and Hayden Birdsong is a purveyor of the kick-change. Both pitches profile as plus, which is a big reason the right-handers are being counted on to provide quality innings in their respective roles with the San Francisco Giants this season; Roupp is in the rotation, while Birdsong is working out of the bullpen.

The early results have been promising. The 26-year-old Roupp, who is scheduled to make his second start on Tuesday night against the Cincinnati Reds, made his season debut on April 2 in a 6-3 Giants win over the Houston Astros. The start wasn’t great — he was removed with the bases loaded and nobody out in the fifth inning and was ultimately charged with three runs — but his eight strikeouts were encouraging. Seven of those strikeouts — and none of the four hits he allowed — came against his curveball. He threw his signature offering 34 times in his 83-pitch effort.

Birdsong has thrown four scoreless innings over two relief appearances. One of his four strikeouts has come courtesy of the kick-change, which he has thrown nine times out of 53 total pitches. The 23-year-old, likewise in his second big league season, has primarily attacked hitters with his high-octane heater (56.6% usage).

The stories behind Roupp’s hook and Birdsong’s changeup? I broached the subjects with the right-handers in Giants camps shortly before the start of the regular season.

———

“I’ve thrown it my entire life,” Roupp said of his curveball. “All that’s really different is that I’m getting stronger with more mobility, and learning about the metrics. In college we didn’t have metrics. So, learning ways to make it move more and spin harder… learning and growing into my body has made it a lot better. For me, having confidence in it is the biggest thing.”

A 12th-round pick out of UNC-Wilmington in 2021, Roupp spun his curveball at 3,056 rpm in his April 2 outing, comfortably within the 2,900-3,100 range he’d described to me. Roupp also said that he “gets about 19 to 22 [inches] of horizontal [movement] and something like negative-11 vert” when he is executing properly. Timing is the key. When he’s out of sync with his delivery it doesn’t come out of his hand exactly as he’d like. Picking up a baseball, Roupp showed me his two-seam fastball grip, then rotated the ball just slightly. He explained that he throws his curveball just like his two-seamer, but “with a snap.”

Roupp’s curveball is “pretty slow,” averaging 77.4 mph since the start of last season. He said the speed differential between that and his fastball — his two-seamer averages 93.4 mph — is a big part of its effectiveness. As for its usage, he threw the curve 41% of the time in his first outing, which was slightly less frequently than he did last season (44.1%). With the caveat that one game is nowhere near a large enough sample size to determine what a pitcher’s usage rates will be, that dip was notable given that Roupp told me this spring that his plan was to throw his curve less often this season.

“Coming up through the minor leagues, they were telling me I was throwing it too much,” Roupp said. “That was more about developing my other pitches, though. But while I might throw it 40% of the time, I do think I’m going to lean back a little bit now that I have the changeup and the cutter. The changeup was new last year, and the cutter this year. I want to implement those and get people off my curveball so that it’s even more effective at the big league level.”

———

“I have a high-vert heater with pretty good velo,” Birdsong said when asked to describe his full arsenal. “My curveball is the opposite of my fastball in that it’s just straight down; it’s negative-15 vert when it’s good. My slider is kind of in development and is more of a cutter. My changeup is just my changeup. I started throwing it last year, and it’s developed into one of my better pitches.”

That would of course be the kick-change. The right-hander supposedly learned it at Tread Athletics… except, that’s not true. Birdsong explained that while “everybody says that,” he’s never been to Tread, nor has he talked to anyone who works there. He simply watched a Tread video, then began experimenting with the grip the following day.

“I started playing catch with it — this was in spring training — and I’m not sure I can even remember who my catch partner was,” said Birdsong, whom the Giants took in the sixth round of the 2022 draft out of Eastern Illinois. “It might have been Spencer Bivens. But my changeup had been horrible the year before. It was basically just a bad fastball, a 15-vert slower fastball. That’s all it was. I needed to find another grip, one that wasn’t a splitter — I didn’t want to mess with one of those — so I started looking at videos. That one popped up.”

Birdsong’s previous attempts to find a quality changeup had all been for naught, but when he saw the kick-change, he thought, “Let’s try it.” To his knowledge, he’d never thrown one “under nine vert.” All of a sudden, he had one that was close to zero. The first coach he approached with that news didn’t believe it.

“I was throwing it, and it was tumbling,” Birdsong said. “It was doing what I wanted it to do. I told [bullpen coach Garvin Alston] that I’d thrown a changeup in the bullpen and it was negative vert. He goes ‘No.’ Then he was like, ‘Let me go take a look [at the data].’ I asked him about it the next day and he said, ‘Keep throwing it.’”

As Davis Martin and Matt Bowman explained here at FanGraphs last September, the pitch that Birdsong is now throwing has a close-cousin relationship with the better-known split change. While the name is new, the pitch itself really isn’t.

“I saw the video and called it a spike change,” said Birdsong. “I showed the grip to somebody — I forget who it was — and he was like, ‘Yeah, there are some guys who used to throw that. It’s called a kick-change.’ All it is, really, is that you’re kicking the axis of the ball. Whatever you call it, it works for me.”

During the course of my spring training coverage (especially right at the end), I ran into the Giants affiliates a couple of times as I trailed the Brewers and Dodgers farm systems. I saw enough to make a few tweaks to the Giants prospect list, which I have brief notes on below. You can see the complete updated list over on The Board. I’ve also included notes on a few recent trades.

Toolsy Outfielders With Strikeout Risk Who Have Moved Up

Dakota Jordan’s swing has changed (mostly his posture throughout the swing), and I think it gives him a better chance to hit. I was way out on him making any kind of viable contact before last year’s draft, but he has loud showcase tools (power/speed) and now we’ll see if the proactive changes make a difference for his contact ability. He has also looked good in center field, including highlight reel play in which he collided with the wall at Papago Park, but then forgot how many outs there were and spiked the baseball:

Man, it sure is nice to have baseball back, and we’ve already been treated with fantastic performances from across the league. There have been the usual Aaron Judge home runs, the return of Jacob deGrom’s dominance, the stretch of surprising Marlins walk-offs, and so much more. But for the next few minutes, we’re going to focus on the elite defense on display so far this season.

Great defense can come about in so many ways. Sometimes, it’s a feat of raw athleticism, while other excellent plays are a testament to the fielder’s intuition and preparation. Aside from actually making the plays, fielders must consider a multitude of factors in an extremely limited amount of time; the best fielders are also the best real-time processors. The best way to explain this is by watching it in action.

Let’s start with none other than defensive wizard Matt Chapman: Read the rest of this entry »

Alan Roden roped baseballs with regularity this spring, helping himself to land not only a roster spot, but also an Opening Day start in right field for the Toronto Blue Jays. Showing signs that he’s ready to take off at the MLB level, the 25-year-old left-handed hitter punished Grapefruit League hurlers to the tune of a 1.245 OPS and a 220 wRC+. He also coaxed six free passes and fanned just four times over his 37 plate appearances.

More than spring training results factored into his first big-league opportunity. Building on a strong 2024 season, split between Double-A New Hampshire and Triple-A Buffalo, Roden has been adding pop to his profile. Previously known more for his bat-to-ball skills than for his ability to clear fences, the erstwhile Creighton University Bluejay is now looking to lift.

Having read of Roden’s efforts to generate more power, I asked him how he’s gone about impacting the ball with more authority.

“I think it’s less of the actual impact that’s better,” Roden told me at Blue Jays camp. “It’s more the shape of the ball off the bat, directionally. The exit velocities are high enough to where if I’m getting in the air to the pull side, it’s going to go. That’s where the damage comes from, hitting the ball with more ideal launch angles.”

Roden has a B.A. in physics, so understanding the aerodynamics of ball flight, and the swing paths that produce results, comes with the territory. Explaining his mechanical adjustments was a simple exercise for the Middleton, Wisconsin native. Read the rest of this entry »

Every year, most teams hold some sort of team bonding, social event during spring training. The specifics of the event vary from team to team, but frequently they include renting out a movie theater and showing some cloying, inspirational movie like The Blind Side, Cool Runnings, Rudy, or better yet, a documentary like Free Solo. Regardless of the team’s outlook on the year, the goal is to get the players amped up for the season and ready to compete on the field, even if the competition in question is for fourth place in the division.

But what if instead of taking the clichéd route, teams actually tried to select a movie that fits their current vibe, one that’s thematically on brand with the state of their franchise? They won’t do this because spring training is a time for hope merchants to peddle their wares, even if they’re selling snake oil to sub-.500 teams. But spring training is over now, the regular season has begun, and it’s time to get real. So here are my movie selections for each National League team, sorted by release date from oldest to newest.

If you’re interested in which movies I selected for the American League teams, you can find those picks here. Read the rest of this entry »

Matt Chapman came in at no. 3 when our 2015 Oakland Athletics Top Prospects list was published in February of that year. Assigned a 45 FV by our then lead prospect analyst Kiley McDaniel, Chapman had been drafted 25th overall out of Cal State-Fullerton the previous summer. Playing most of his initial professional season in the Low-A Midwest League, the 21-year-old third baseman swatted five home runs and put up a modest .672 OPS over 202 plate appearances.

What did Chapman’s 2015 scouting report look like? Moreover, what does he think of it all these years later? Wanting to find out, I shared some of what McDaniel (now with ESPN) wrote and asked Chapman to respond to it.

———

“A standout hitter and pitcher for Fullerton that didn’t have much first-round buzz for reasons I didn’t understand.”

“He was thinking like I do,” Chapman replied. “I thought I was a little underrated. Obviously, the A’s took a chance on me and it all worked out. But that’s funny, because I thought I had all the tools. I just wasn’t getting the love.”

“Chapman, has an 80 arm and has been into the high 90s on the mound, but is mostly an arm-strength guy with a short track record of pitching.” Read the rest of this entry »

If you’re not familiar with Jerry Weinstein, you should be. He is a catching coach legend. After decades with the Rockies, he recently jumped to the Cubs, and lucky for us, he’s quite active online talking about catching philosophies and training. One thing he has discussed recently is “slam dunk” framing.

Some cues in baseball are universal, and slam dunk framing is one of them. It looks just like how it sounds: Catchers take their glove and quickly snap it down as if they were dunking a basketball. What’s the intention? By moving their glove down in a quick, fluid motion on pitches at the top of the zone, they’re attempting to give the impression that these pitches are lower than where they actually crossed the plate.

While this could easily just be another solo Patrick Bailey framing post, there is one other guy in particular, Cal Raleigh, who deserves to squat in the spotlight. To set the stage, here are the leaders in Strike% in Zone 12 (the upper third in the shadow zone) last season: Read the rest of this entry »

In which ways would a fully-implemented Automated Ball-Strike System [ABS] impact pitching? According to a coordinator I spoke to, one effect could be a further increase in the number of power arms who can get away with attacking the middle area of the zone. Conversely, crafty finesse types will become even less common, as getting calls just off the corners will no longer be possible.

Count Chris Bassitt among those not enamored with the idea.

‘“If you go to a full ABS system, you’re going to develop more throwers and the injury rates are going to spike,” opined the 36-year-old Toronto Blue Jays right-hander. “Then you’ll have to go back to pitching. The only way to stay healthy is to pitch. That’s never going to change in our sport. No matter how many people want to do something different, you have to pitch. There are obviously a number of facets for why people get hurt at the rate they’re getting hurt, but the answer for the injury history of the sport for the last five, ten years is more throwers. I don’t agree with it.”

Seattle Mariners pitching strategist coordinator Trent Blank offered a more measured take on the ABS. Read the rest of this entry »

You’ve all heard the terms “luddite” and “sabotage” before. They’re words with pejorative connotations: The former is someone who distrusts technological progress; the latter is the act of conspiring to destroy from within. Luddites and saboteurs are rubes and terrorists, respectively, in modern vernacular.

These are more recent linguistic developments than you might think. Both words come from organized labor movements in which workers saw machines lowering product quality and putting entire industries’ worth of skilled craftsmen out of business in a time of economic precarity. They reacted to this existential threat the way you’d expect: by destroying it. Throwing one’s body on the gears and the levers until the machine stops working would one day become a vivid political metaphor, but to the original Luddites and saboteurs, it was a literal thing.

If the winter is a time for dreams, the spring is a time for solutions. Your team may have been going after Juan Soto or Aaron Judge or Shohei Ohtani, depending on the offseason, but short of something going weird in free agency (like the unsigned Boras clients last year), if you don’t have them under contract at this point, they’ll be improving someone else’s club. However, that doesn’t mean that spring training is only about ramping up for the daily grind. Teams have real needs to address, and while they’re no doubt workshopping their own solutions – or possibly convincing themselves that the problem doesn’t exist, like when I wonder why my acid reflux is awful after some spicy food – that doesn’t mean that we can’t cook up some ideas in the FanGraphs test kitchen.

This is the final piece in a three-part series in which I’ll propose one way for each team to fill a roster hole or improve for future seasons. Some of my solutions are more likely to happen than others, but I tried to say away from the completely implausible ones. We’ll leave the hypothetical trades for Bobby Witt Jr. and Paul Skenes to WFAN callers. Also, I will not recommend the same fix for different teams; in real life, for example, David Robertson can help only one club’s bullpen. I wrote about the teams in the two East divisions last Wednesday, and then covered the Central divisions on Friday. Today, we’ll tackle the 10 teams in the West divisions, beginning with the five in the AL West before moving on to their counterparts in the NL West. Each division is sorted by the current Depth Charts projected win totals.

Texas Rangers: Reunite with Kyle Gibson
Look at the Rangers in our Depth Charts projection and glance down at the pitchers. Do you see a problem? We project the Rangers to have a decent rotation, right at the back of the top 10, but that also relies on a lot of innings from pitchers who have not been able to throw many in recent years. Jacob deGrom and Tyler Mahle are both projected to throw more innings apiece than the two of them have thrown combined over the last two years. I’d love to see 270 innings from deGrom and Mahle, but to count on that is just begging for a sad story. I probably believe in Kumar Rocker and Jack Leiter more than most, but neither of them should be counted on to solidify an injury-depleted rotation in 2025.

The Rangers need a reliable innings-eater, and old friend Kyle Gibson is still out there. He has made at least 30 starts in five of the last six full seasons, with the one time he didn’t reach that threshold coming in 2019, when he made 29 starts, appeared in 34 games, and put up 2.6 WAR across 160 innings — the fewest innings he’s thrown in that span, excluding 2020. He’s probably never again going to be as good as he was in 2021, when he was an All-Star with Texas before getting traded to the Phillies and finished with a 3.71 ERA, a 3.87 FIP, and 3.1 WAR, but Gibson comes with a fairly high floor. His performance last year with the Cardinals (4.24 ERA, 4.42 FIP, 1.5 WAR, 169 2/3 innings) was his least-productive campaign during that 2018-2024 stretch, but even that would benefit the Rangers right now.

Seattle Mariners: Add some Tork to the lineup
The Mariners have gotten more out of Luke Raley than they’ve had any right to, but he remains a platoon first baseman, with a .575 OPS in the majors against lefties. Even if he can do better than that — ZiPS thinks he’ll put up about a hundred more points of OPS in 2025 — he’s not David Ortiz against righties, so it’s hard to just give him a full-time job at first. The likely candidates to pair with Raley are thoroughly uninteresting, so why not look at Spencer Torkelson, a player who is just begging for a change of scenery? The Tigers have clearly soured on him; otherwise, they likely would not have signed second baseman Gleyber Torres and moved Colt Keith to first base to start there over Torkelson. He’s still young enough to have some upside and get things back on track, but even if he doesn’t ever reach his full potential, he ought to at least beat up on lefties. The Mariners could use more power, and I doubt the price tag will be high.

Houston Astros: Add a very boring arm
The Astros dug themselves a hole early on in 2024, in large part because of a spate of pitching injuries that tested their depth to the breaking point. Houston’s rotation ought to be good, but there still are a number of pitchers with injury concerns, once again leaving the team vulnerable to some bad health luck. The Astros could use some veteran depth to preemptively reinforce the rotation just in case someone goes down, and I think for them, Lance Lynn is the most interesting free agent still available.

The Astros are skilled at refining pitch arsenals, for both prospects and veterans, and Lynn has the weirdest repertoire of the remaining free-agent starters. Rather than the standard fastball-breaking-offspeed mix, Lynn basically throws a bunch of slightly-to-moderately different fastballs, making him the type of pitcher who could benefit from Houston’s wizardry. A sweeper could cause some additional tension for batters compared to his cutter, and he’s never really had a refined offspeed offering to use as a putaway pitch against lefties. The specifics would be for the Astros to figure out. Lynn also has expressed a willingness to pitch out of the bullpen after teams started inquiring about using him as a reliever, so even if Houston’s rotation remains in tact for the whole season, Lynn could still have a role.

Athletics: Get Sandy before heading to the desert
The good: The A’s actually spent some money this winter. The bad: We still project the A’s to have a losing record. The really bad: Our Depth Charts project the A’s to have a worse starting rotation than the White Sox. The Marlins are clearly in the shopping mood, having already sent away Jesús Luzardo, and with teams likely waiting to see how Sandy Alcantara fares after returning from Tommy John surgery, the A’s have an opportunity to jump the 2022 NL Cy Young’s trade market and steal a march on the better wild card contenders. A potential wrinkle here: The Yankees may be in the market for Alcantara now that Gerrit Cole is going to miss the 2025 season while recovering from Tommy John surgery. Still, the A’s shouldn’t let that deter them from targeting an ace at a time when he could be relatively affordable.

Los Angeles Angels: Hire a team of archaeologists to design a very complex treasure hunt that convinces Arte Moreno to sell the team so that he’s free to go on an Indiana Jones adventure
I admit it, I’m at a loss for words with the Angels. In some ways, they’re actually worse off than the White Sox, in that Chicago at least has a reasonable long-term plan while the Angels keep teetering between strategies that are either unclear, unrealistic, or both. Their moves reflect their extreme short-term thinking, leaving the organization without a coherent path to winning now or winning later. Leadership has to come from the top, and Moreno continues to show he is incapable of fixing things. Case in point: The Halos spent this offseason adding veteran depth pieces. These would’ve been smart moves if the Angels were already a good team and looking to patch up their few remaining areas of weakness. That, of course, is not the case. The Angels need to accept that they’re lost before they can move forward and begin to assemble a winning team while Mike Trout is still around. But as long as they keep following an ineffective leader, they’re going to keep walking in circles.

Los Angeles Dodgers: Find a weird reclamation project
This one was a struggle because the Dodgers, while not having the highest median win projection of any team in ZiPS history (that’s still the 2021 Dodgers), they have the highest floor, with no obvious weaknesses anywhere. I guess the one thing the Dodgers are missing is that random broken-down reliever that you forget still plays baseball until they inevitably fix him. I’d love to see if Daniel Bard has another improbable comeback left in him, or maybe Adam Cimber, because a star in the sky disappears whenever a sidearmer loses his job.

Arizona Diamondbacks: See if the Yankees are interested in Jordan Montgomery
As I mentioned in the A’s section, Cole’s Tommy John surgery is a massive blow to the Yankees as they look to defend their American League pennant in 2025. Will Warren has a good shot at being a pretty solid rotation fill-in, but with Luis Gil also out for a while and Nestor Cortes now on the Brewers, the team now has just about zero starting pitching depth left. Jordan Montgomery and the Yankees have a good history, and there’s an obvious need now. Montgomery really struggled in 2024, to the point that Arizona owner Ken Kendrick said publicly that adding the lefty was a “horrible signing.” The Diamondbacks also have plenty of rotation options, so many, in fact, that RosterResource currently projects Montgomery to pitch out of their bullpen. They surely won’t get much in return for him, and they should be prepared to eat a good chunk of his remaining salary, but if they want to move on from him and maybe even get a prospect or two in return, this is the way to do it.

San Diego Padres: Sign David Robertson
The Padres’ bullpen is hardly a dumpster fire, but it is kind of top-heavy, and we project everybody after the fifth option (Yuki Matsui) to be at or below replacement level. There’s not a lot of financial flexibility right now in San Diego for various reasons we won’t go into here, but if the Padres are looking for marginal gains on a budget, David Robertson is by far the best move they could make. They shouldn’t have to spend much to get him, considering he’s 40 years old and remains unsigned in the second week of March, but he is coming off a very good season and is comfortable pitching in a variety of bullpen roles.

San Francisco Giants: Inquire about Jesús Sánchez
The Giants are likely a tier below the Diamondbacks and Padres in the NL Wild Card race, but they’re still close enough that short-term improvements matter. San Francisco’s designated hitter spot is bleak, and the player we have getting the most plate appearances there, Jerar Encarnacion, was in an indie league for much of last season and put up a .277 on-base percentage in the majors. The Giants should see what it would take to get Jesús Sánchez from the Marlins. He’s never developed into a big home run hitter despite solid hard-hit numbers, in large part because he’s never generated much loft. He’s also a spray hitter, and last season, 13 of his 25 doubles were line drives hit the opposite way. It’s the type of game that could be better suited for the spacious Oracle Park. Sánchez would provide a left-handed complement to Encarnacion, and he’s good enough to play all three outfield positions if needed.

Colorado Rockies: Find the next Nolan Jones and Brenton Doyle
Since the departure of former GM Jeff Bridich, the Rockies have made quite a bit of progress in no longer treating prospects as annoyances, and they now give internal, lesser prospects chances to surprise them. The last bit is important, as the Rockies of five or six years ago would never have given someone like Nolan Jones or Brenton Doyle enough playing time to break out in the majors. Doyle hit 23 homers and stole 30 bases in 2024 while winning his second Gold Glove in as many seasons, and although Jones struggled last year, he was hurt on and off and should be expected to at least split the difference between that performance and his 2023 production.

Considering this, the Rockies should go full-carrion bird as the season approaches. Colorado ought to be in on any and all mildly interesting players who are shut out of major league opportunities in 2025. Among the guys the Rockies should target are Mickey Gasper, Edouard Julien, Addison Barger, Shay Whitcomb, Curtis Mead, and Leo Jiménez. They may never develop into stars, but the Rockies need to be willing to throw everything at the wall and hope to find at least a few productive players.
