Kyle Karros has quietly emerged as one of the most promising prospects in the Colorado Rockies system. Since being drafted in the fifth round two years ago out of UCLA, the 23-year-old third baseman has slashed .303/.393/.455 with a 134 wRC+ over 1,000 plate appearances. His numbers this season are in that same ballpark. Over 305 plate appearances, the bulk of them with the Double-A Hartford Yard Goats — he was promoted to the Triple-A Albuquerque Isotopes on July 18 — Karros is slashing .297/.398/.463 with a 142 wRC+.
As our lead prospect analyst Eric Longenhagen wrote back in January, the son of former Los Angeles Dodgers slugger Eric Karros “needs to develop power.” The progeny’s right-handed stroke produced 15 home runs a year ago, and this season he has left the yard six times. Given his 6-foot-5, 220-pound frame, there is a pretty good chance that he will tap into his power with more experience. Longenhagen recently updated Karros to a 40 FV prospect while ranking him 14th in the Rockies system.
On the eve of his becoming an Isotope, Karros discussed his approach to hitting, as well as his baseball relationship with his father.

David Laurila: How would you define yourself as a hitter?
Kyle Karros: “I’ve really bought into being a complete hitter first, and allowing power to just come naturally. I’ve kind of always put an emphasis on not chasing homers. Doubles are my game. I also feel like you grow into home runs. You learn what counts you can take advantage of. You get more efficient with your swing. But right now — this year, especially — I’ve bought into really controlling the zone. I think what allows me to do that is having a right-center type of approach. That allows me to let the ball travel a little deeper. If I’m on a fastball to right-center, that puts me on offspeed where I’m able to pull and elevate.”

Tyler Glasnow was 21 years old and full of promise as he sat atop our 2015 Pittsburgh Pirates Top Prospects list when it was published in January of that year. Our then-lead prospect analyst Kiley McDaniel gave plus grades to both Glasnow’s heater and his hook, opining that the tall right-hander had no. 2 starter potential.
Despite an injury history that includes Tommy John surgery, Glasnow has largely lived up to expectations. Drafted 152nd overall in 2011 out of William S. Hart High School in Santa Clarita, California, he was traded to the Tampa Bay Rays in July 2018 (a deadline deal Pirates fans would love to forget) and logged a 3.20 ERA and 3.10 FIP over 71 starts in his five-plus seasons there. Subsequently swapped to the Los Angeles Dodgers in December 2023, Glasnow has a 3.47 ERA and a 3.28 FIP over 31 starts with his current club. He is top-of-the-rotation quality when fully fit, but he has had trouble staying healthy. Just this season, he was out from late April until early July with shoulder inflammation.
What did Glasnow’s 2015 FanGraphs scouting report look like? Moreover, what does he think about it all these years later? Wanting to find out, I shared some of what McDaniel wrote and asked Glasnow to respond to it.
———
“Glasnow was drafted in the fifth round out of high school in 2011 as a low-profile pure-projection bet with fringy-to-average stuff and a limited track record.”
“That’s probably pretty accurate,” Glasnow replied. “I was fifth round, just more projectable, and throwing 89-91 [mph]. I had a decent curveball, but it wasn’t very good yet. My stuff was decent for high school, but compared to pro ball, not really. I was lower velo, mostly just two pitches, and I had a very bad changeup.”
“He blew up in 2013, dominating Low-A with a fastball that hit 97 mph. He continued his progress at High-A in 2014, sitting 93-96 mph and hitting 98 mph.”Read the rest of this entry »
When the Red Sox acquired Dustin May from the Dodgers at Thursday’s trade deadline, they brought on board a starter with a pair of elbow surgeries in his rearview. The 27-year-old right-hander had Tommy John in 2021, then needed to have a flexor tendon repaired in 2023. Boston also brought on board a pitcher who has matured admirably since he was drafted 101st overall in 2016 out of a Justin, Texas high school.
“As a pitcher, I haven’t changed a whole lot,” May told me prior to the trade. “My stuff is pretty comparable to what it was before. But off the field, I’ve changed a lot. A lot of life changes have happened through the surgeries — a lot of good things — and I feel like I’ve definitely improved as a person and as a husband.
“We’re all very blessed, and talented, to be here,” he added. “Stuff can be taken away from you in an instant, and you can have no control over it. No matter how hard you work, or what you put into it, life can come at you very fast at times.”
A serious health scare last summer is an example. May suffered a torn esophagus that required emergency surgery. Less scary, but nonetheless troublesome, was his not bouncing back from TJ as well as he’d hoped. Read the rest of this entry »
Jordan Hicks wasn’t yet reaching triple digits when our 2017 St. Louis Cardinals Top Prospects list was published in January of that year. Ranked 14th in the system at the time, the 2015 third-round pick out of Texas’s Cyprus Creek High School was throwing — per Eric Longenhagen — a comparably modest 96 mph. That soon changed. The high-octane right-hander went on to eclipse the 100 mark that summer, and early the next season he was clocked at 105 while pitching in the big leagues against the Philadelphia Phillies.
He’s since ridden a bit of a rollercoaster. Hicks followed a solid 2018 rookie campaign by logging 14 saves and a 3.14 ERA over two-plus months in 2019, but he blew out his elbow in June and underwent Tommy John surgery. As a Type-1 diabetic, he sat out the entire 2020 pandemic campaign. More elbow woes cropped up in 2021, limiting him to just 10 big league innings.
Changes of address have been notable in Hicks’ subsequent seasons, as have his job descriptions. The righty remained a reliever throughout 2023 — a year that saw him dealt from the Cardinals to the Toronto Blue Jays at the trade deadline — but he was then converted to a starter after signing as a free agent with the San Francisco Giants prior to last season. His success in that role having been a mixed bag, Hicks now finds himself back in the bullpen — with yet another team. Acquired by the Boston Red Sox as part of last month’s Rafael Devers trade, he has gone on to make nine appearances and register a pair of saves while allowing four earned runs over seven 1.3 innings. His fastball velocity has topped out at 101.5 mph.
What did his 2017 FanGraphs scouting report look like? Moreover, what does he think about it all these years later? Wanting to find out, I shared some of what Eric wrote and asked Hicks to respond to it.
———
“A relatively undercooked prep arm from the 2015 draft.”
“Undercooked? I guess if you’re cooking a steak and you want it medium, I was rare,” Hicks said of that quote. “I didn’t have a lot of innings. At that point I had only thrown around 50 innings, and another 50 in high school. So, it was maybe 50 varsity innings and 50 pro innings. I think that’s probably what he meant by that.”
“His fastball sits 90-94, will touch 96, and comes in at an odd angle with some late sink.”Read the rest of this entry »
Austin Hays is having a productive-when-healthy season with the Cincinnati Reds. The 30-year-old outfielder has missed time with a calf strain, a hamstring strain, and a foot contusion, but he’s also slashed .282/.338/.510 with 10 home runs in 228 plate appearances. Moreover, his 128 wRC+ and .360 wOBA are both second on the team (behind Elly De La Cruz) among those with at least 140 PAs.
His résumé is that of a solid hitter. From 2021-2023— his first full seasons in the majors — Hays had 97 doubles and 54 home runs, as well as a wRC+ ranging between 106 and 111. Those three seasons were spent with the Baltimore Orioles, who subsequently swapped him to the Philadelphia Phillies in exchange for Seranthony Domínguez and Cristian Pache a few days before last July’s trade deadline. Hays’s 2024 campaign was the worst of his career. Hampered by injuries and illness — a kidney infection proved most problematic — he had a 97 wRC+ while playing in just 85 games. The Reds then inked him to a free agent contract over the winter,
Which brings us to the crux of this column’s lead item: the reasons behind the success he’s currently having.
“Consistency is probably the biggest thing,” Hays told me. “There’s not always an adjustment to be made. Sometimes it’s just the game [and] you’re being pitched tough. I don’t want to be altering too much of what I do well. In the past, I would sometimes pay too much attention to what the pitcher was doing and try to adjust to that. Staying strong to my strengths — locking in on those strengths — is going to help me over the course of 162 [games].” Read the rest of this entry »
Tyler Mahle was 23 years old and had 20 big league innings under his belt when our 2018 Cincinnati Reds Top Prospects list was published in January of that year. A seventh-round pick out of an Orange County high school five years earlier, Mahle was ranked fourth in the system, with Eric Longenhagen assigning him a 50 FV.
Mahle has gone on to have an injury-marred career. Most notably, he underwent Tommy John surgery in May 2023, less than a year after he’d been dealt from the Reds to the Minnesota Twins in exchange for Christian Encarnacion-Strand, Spencer Steer, and Steve Hajjar at the trade deadline.
When healthy, the 30-year-old right-hander has been a quality pitcher more often than not. In 2021, he made 33 starts for Cincinnati and went 13-6 with a 3.75 ERA and a 3.80 FIP over 180 innings. Moreover, Mahle was on track for an even better season when he went on the shelf seven weeks ago with what has since been diagnosed as a right rotator cuff strain. In 14 starts comprising 77 innings with the Texas Rangers, Mahle had a record of 6-3 to go with a 2.34 ERA and a 3.37 FIP. His status for the remainder of the current campaign is unclear.
What did Mahle’s 2018 FanGraphs scouting report look like? Moreover, what does he think about it all these years later? Before he went on the injured list, I shared some of what Eric wrote and asked Mahle to respond to it.
———
“After 24 hyper-efficient starts at Double and Triple-A, Mahle finally got a four-start cup of coffee in Cincinnati at the end of the season. His ability to locate was not on display in the big leagues, but it’s what got Mahle there.”
“Not great,” Mahle said of his four starts in 2017. “I was wild. My first two or three starts, I’d thrown something like 50 pitches by time I got through two innings. So yeah, not very efficient. But I got through it. Then I got off to a decent start the next year, in 2018, but pitched kind of hurt toward the end of that season.”
“He has above-average fastball command despite a somewhat noisy delivery; it should tighten another half-grade as Mahle hits his peak.”
“Hmm… yeah, my delivery back then was super stiff,” he said. “I held my glove up high and it stayed there until I broke my hands. Looking back, my delivery was, again, super stiff. A lot has changed there.
“Honestly, I don’t remember exactly,” Mahle said when asked when he made the adjustment. “It must have been with [Reds pitching coach Derek Johnson]. We kind of took away some movement in the hands. Instead of going from up high to down low, we started going from the belt to make it a little simpler.”
“His stuff is middling, spearheaded by a slightly above-average fastball/slider combination out of which Mahle squeezes every ounce of juice due to his ability to locate.”
“I was pitching with pretty much all fastballs at that time,” the righty recalled. “My slider was super inconsistent. I didn’t have a splitter like I have now. I basically just relied on the fastball.”
“He adds and subtracts from his fastball, exhibiting velocities anywhere from 88 to 95, touching 96 regularly, and maxing out at 98.”
“Yeah, but not so much anymore,” Mahle admitted. “I kind of live low 90s now and will top around 95. But relying so much on my fastball back then, I had to try to overpower guys with it. I had to try to throw it hard.”
“While Mahle’s change doesn’t have terrific movement, his ability to manipulate pitch speed without noticeable arm deceleration helps make it a viable third offering.”
“Yep. I mean, that was me,” Mahle said. “I didn’t have much of a changeup, so I had to try to place it in the zone, or wherever I was trying to get it. Like my slider, it was just super inconsistent. The arm speed… I actually feel like I probably did have to change it, based on what I was throwing. I maybe telegraphed a lot back then. Now I can throw everything with pretty much the same arm speed.”
“His stuff isn’t overwhelming, but his command should allow him to survive as an average big league starter.”
“That’s how I’ve gotten by,” the nine-year veteran acknowledged. “My command, still now… like, my fastball isn’t an overpowering pitch velo-wise, but I locate it. I also get some good ride on it. Back then, I didn’t know that. I just knew that it did well up in the zone. But yeah, I kind of lived off the location of my pitches.
“I understand everything a lot more now,” Mahle added. “I know why it works well up in the zone, and what the separation is on each pitch, and why they’re doing what they’re doing. Compared to now, back then I was pretty much just throwing.”
Andrew Abbott is establishing himself as a top-shelf starter. Now in his third big league season, the 26-year-old southpaw has a record of 8-1 to go with a 2.13 ERA and a 3.42 FIP over 97 1/3 innings. Moreover, he represented the Cincinnati Reds in last week’s All-Star Game. An honorable mention in Ben Clemens’ ongoing Trade Value series, Abbott merits attention — and he’s been receiving his fair share of it here at FanGraphs. Jake Mailhot wrote about him in mid-May, and Michael Baumann followed up by doing so in mid-June; Baumann also covered Abbott as a rookie in this piece from August 2023.
Accuse us of being AbbottGraphs if you’d like, but the University of Virginia product is getting yet another write-up courtesy of yours truly. Being a big fan of crafty lefties, I wasn’t about to pass up the opportunity to talk to Abbott — as well as to others about Abbott — when the Reds visited Fenway Park earlier this month.
Not surprisingly, his self-assessment pretty much matched what I’ve read and seen.
“I’m not an overpowering guy,” acknowledged Abbott, whose 92.4-mph fastball velocity ranks in the 21st percentile. “Mixing speeds and getting guys off balance has always been the name of the game with me. That and staying in the zone as much as possible. I also take pride in being available, being able to throw 100 pitches every fifth day.” Read the rest of this entry »
Merrill Kelly is having a rock-solid season. Over 21 starts comprising 122 innings, the 36-year-old right-hander has a 9-6 record to go with a 3.32 ERA and a 3.48 FIP. Those numbers are pretty much par for the course. Over the past three-plus seasons — all with the Arizona Diamondbacks — Kelly has made 97 starts and gone 39-22 with a 3.42 ERA and a 3.75 FIP. Neither overpowering nor of ace quality, Kelly is nonetheless a good pitcher who adds value to a big league rotation.
He could soon be taking the mound for a different team. Signed by the D-backs in December 2018 following a four-season stint in the KBO, Kelly is now on the doorstep of free agency; should Arizona decide to be sellers at the deadline, he could find himself in another team’s uniform come August 1. If that happens, the club that acquires him would be getting a known commodity. He has put up between 2.2 and 3.2 WAR in four of his last five seasons, with the exception coming last year, when injuries limited him to just 13 starts and 73 2/3 innings. His overall big league ledger reads: 62-49, 161 starts, 946 1/3 innings, 3.76 ERA, 3.97 FIP, 13.9 WAR.
With free agency looming, I spoke with the veteran hurler earlier this year about his approach to pitching, his evolution on the mound, and his steady performance since returning stateside.
“That’s an interesting question,” Kelly replied when asked how how he gets hitters out. “I would say that I do it in a lot of different ways. Ideally, I would like to get them out on as few pitches as possible. I guess you’d consider that a little bit more old school. Read the rest of this entry »
Payton Tolle is the top pitching prospect in what is arguably baseball’s best farm system. Drafted 50th-overall last summer by the Boston Red Sox out of Texas Christian University, the 22-year-old left-hander features a fastball that Eric Longenhagen has assigned a 70 grade, and not just because of its high octane. Per our lead prospect analyst, the 6-foot-6, 250-pound hurler possessed “the 2024 draft’s most deceptive secondary traits,” which included seven-and-a-half feet of extension.
I asked Tolle about his four-seamer, which sat 95 mph when I saw toe the rubber for the Double-A Portland Sea Dogs versus the Hartford Yard Goats 10 days ago.
“The velo is something we’ve kind of driven hard ever since I got to the Red Sox org,” said Tolle, who was 90-92 in college and is now topping out at 98-99. “I’m buying into the system, buying into how the velo is going to change how everything looks. I also understand that more swing-and-miss is going to come at the top of the zone. At Wichita State, my first year, I felt like I was almost more sinkers, but then I switched up my grip. I brought my fingers closer together and started to have more ride on it.”
Tolle transferred from Wichita State to TCU for his junior year, where he — along with the Horned Frogs coaching staff — “really dove into how the fastball plays and what we can play off of it.” Since turning pro, that evolution has continued with a heavy emphasis on secondary offerings. Whereas his fastball usage as an amateur was often 70-75%, it has been closer to 50% in his recent outings. A work-in-progress changeup has become more prevalent — Tolle got bad swings on a few of them when I saw him in Portland — but a hard breaking ball is currently his top option behind his heater.

James Tibbs III might best be described as a hitting rat. Drafted 13th overall last year by the San Francisco Giants out of Florida State University, and subsequently shipped to the Boston Red Sox in last month’s blockbuster Rafael Devers deal, the 22-year-old outfielder lives and breathes baseball — particularly the part that entails standing in the batter’s box. From a young age, Tibbs has doggedly worked on honing his left-handed stroke.
An Atlanta native who attended high school in nearby Marietta, Tibbs excelled collegiately, slashing .338/.462/.685 over three seasons at the ACC school, with a 28-homer junior campaign further enhancing his profile. And he’s continued to hit in pro ball. He played just 26 games after inking a contract last summer, and his results were mixed; he posted a 153 wRC+ in nine games (42 plate appearances) in A-ball, earned a promotion, then went cold in High-A. Now in his first full professional season, he’s back to doing what he does best: bashing baseballs. Tibbs put up a 132 wRC+ with a dozen home runs in High-A prior to the trade, and since joining his new organization, he has logged a 107 wRC+ over 86 plate appearances while acclimating to Double-A.
Ranked 14th in what Eric Longenhagen called “the best farm system in baseball” when our Red Sox Top Prospects list was published in late June, the promising young outfielder was assigned a 45 FV, with raw power graded as his best hitting tool. Tibbs sat down to talk hitting prior to a recent Portland Sea Dogs home game.
———
David Laurila: You were drafted one year ago. Are you the same hitter now, or has anything meaningfully changed?
James Tibbs III: “I’m pretty much the same. It’s what’s gotten me this far, and I’ve kind of tried to replicate that as much as possible. I’ve never been one to try to make changes unless it’s absolutely necessary, because I play off of feel. I’ll make adjustments based off of that feel, but I’m doing it trying to get back to my base. My base has been pretty consistent for the last… three years? Two years? Something like that.
“I feel like I cover the plate well. I feel like I can see the ball well from where I stand and how I load. I feel like I use my body well in order to get to the spots that I can’t necessarily cover. So yeah, it’s been pretty consistent for the most part.”
