Checking in on Big-name Prospects:
Cam Schlittler, 24, New York Yankees
MiLB Season Stats: 13 G (12 GS)/68.1 IP/2.37 ERA/32.1% K%/8.8% BB%/1.20 WHIP
Weekly Stats: 1 GS/5.1 IP/1.69 ERA/20.0% K%/4.0% BB%/1.88 WHIP
New York Yankees fans who don’t closely follow the farm system are about to get a crash course in prospects. When a team is in win-now mode—and flush with free-agent resources—dealing from prospect depth at the trade deadline becomes expected. If a trade partner values production over projection, they could do far worse than targeting right-hander Cam Schlittler.
The 24-year-old isn’t exactly under the radar—MLB Pipeline ranks him as New York’s No. 10 prospect—but Schlittler has outperformed the typical seventh-round pick and looks like a potential late-round steal. Since his promotion to Triple-A Scranton/Wilkes-Barre, he hasn’t missed a beat. On June 19, he tied a career high with nine strikeouts over five innings, allowing just two earned runs.
Schlittler leans on a well-rounded arsenal, led by a four-seam fastball that touches 98 mph. His slider and curveball are his most effective breaking pitches, and he’s working to refine a splitter. He put it all on display this spring during his first big-league camp, even drawing praise from ace Gerrit Cole for striking out multiple veterans during bullpen sessions.
“I had some good stuff last year, and I was able to show that at the lower levels,” Schlittler said during camp. “Now facing some better hitters, I’m just trying to fine-tune the pitches and work on some orientation stuff. I think I’ve made them happy with what I’ve worked on and some of the results I’ve gotten.”
PLV says Schlittler doesn’t have a bad offering in his Triple-A action yet, and the curveball is a promising offering. He has only thrown in 33 times, but the 45.5% whiff rate is impossible to ignore. When batters do make contact, though, the opposition has success, evident by a .544 xwOBAcon so far.
Schlittler may not project as a future ace in the Bronx, but his profile is built for long-term value. With a strong frame, swing-and-miss stuff, and the potential to log 180+ innings once his timing and splitter command sharpen, he’s emerging as a valuable depth piece and possible back-end starter. Continued strike-throwing at Triple-A could earn him a Yankee Stadium cameo later this year—especially if the Yankees look to manage innings for their veteran arms.
Pitching coach Matt Blake recently named Schlittler as the most MLB-ready of a group that includes Bryce Cunningham, Greysen Carter, and Cade Smith. If a need arises, Schlittler could be next in line.

Weekly Four-Seam Standouts
This section could be a combination of Bubba Chandler (141 on June 17), Jacob Misiorowski (164 on June 20), or Andrew Painter (117 on June 21), week in and week out. Those pitchers are among the cream of the prospect crop, and their fastballs are a large part of their success. Instead of honing in on the player’s managers many already know, here are some other above-average offerings and what makes them worth noting.
Troy Melton, 24, Detroit Tigers
Weekly Four-Seam Grade: 129 Fan4+ in June 17, 2025, start
MiLB Season Stats: 13 G (12 GS)/49.2 IP/4.17 ERA/28.4% K%/7.0% BB%/1.41 WHIP
Most prospects have a “Welcome to The Show” moment shortly after their MLB debut—whether it’s a rough outing that spirals or a faceoff against a superstar that reminds them just how high the bar is. But for Tigers prospect Troy Melton, it’s been more like a string of “Welcome to Triple-A” moments.
Since his promotion, Melton has struggled to find his footing. Through his first 10.2 innings in Toledo, he’s allowed four home runs and been snakebit by some brutal batted-ball luck. He’s still waiting on that breakthrough outing that puts everything together. If there’s a silver lining, it’s this: his strikeout-to-walk ratio remains elite, and his 3.22 xFIP suggests he’s performing much better than his surface-level stats would indicate.
Still, his June 17 start was another tough one—just 1.2 innings, two earned runs, and two walks. The stuff is flashing, no doubt, but the box scores haven’t been kind to the San Diego State product so far at Triple-A.
Miguel Ullola, 23, Houston Astros
Weekly Four-Seam Grade: 116 Fan4+ in June 21, 2025, start
MiLB Season Stats: 13 GS/50.0 IP/3.42 ERA/28.7% K%/15.2% BB%/1.48 WHIP
The 2025 season has been one to forget for Astros pitching prospect Miguel Ullola. The Dominican-born right-hander rocketed through the system and reached Triple-A by age 21, entering this season as a high-upside arm to watch. It was his first time starting a season at that level, and at just 22 on Opening Day, he carried plenty of intrigue. But an injury-shortened Spring Breakout outing led to a rocky April, and things haven’t stabilized since.
Ullola’s lone bright spot came on June 4 with a one-hit gem, but outside of that, it’s been more of the same: electric stuff plagued by erratic control. His most recent start, on June 21—just two days after his 23rd birthday—was emblematic of his season. He went four innings against Las Vegas, allowing two earned runs on four hits and three walks, with four strikeouts. That line has become the norm: high pitch counts, multiple walks, flashes of strikeout potential, and the nagging sense that command remains his biggest hurdle.
Ullola has now issued multiple walks in every outing since May 8. The raw stuff is undeniable—his fastball-slider combo can miss bats at any level—but even Triple-A hitters are disciplined enough to wait for the inevitable mistake. The ceiling is still high, but the floor is dropping fast. If he can’t find consistency as a starter soon, Houston may be forced to consider a bullpen move, where his two-pitch arsenal could play up in shorter bursts.
Welcome to the Bigs
Jack Perkins, 25, Athletics
MiLB Season Stats: 9 GS/44.0 IP/2.86 ERA/38.4% K%/11.3% BB%/1.02 WHIP
Debut: 3.0 IP/0.00 ERA/20.0% K%/0% BB%/0.33 WHIP
The Athletics’ Jack Perkins injected a spark into an otherwise quiet afternoon in Sacramento, tossing three scoreless relief innings on just 30 pitches during Sunday’s 3–0 loss to the Guardians. Oakland’s No. 9 prospect per MLB Pipeline, Perkins allowed just one hit, struck out two, and flashed a 98 mph fastball, offering a tantalizing glimpse of the arm that earned him back-to-back Pacific Coast League Pitcher of the Week honors earlier this month.
“He looked really under control for a debut,” A’s manager Mark Kotsay said after the June 22 game. “It was a good landing spot for him. … Those are the type of outings that we need from the bullpen to give us a chance to [win]. Impressive debut. He pounded the zone.”
Perkins’ efficiency couldn’t be overstated—he recorded nine outs on just 30 pitches, with 21 of them going for strikes. In that small sample, he showcased his full arsenal. The sinker-sweeper combo led the way, but he also mixed in a sharp slider and a cutter, keeping Guardians hitters guessing. His sequencing was particularly effective: five of his eight whiffs came off the cutter or slider.
A fifth-round pick out of Indiana in the 2022 MLB Draft, the Kokomo native tore through the system this season, posting a 2.86 ERA and a 38% strikeout rate in Triple-A Las Vegas. He found another gear in June, and the A’s rewarded his dominance by selecting his contract.
A starter by trade, Perkins may find himself toggling between roles as Oakland continues its fluid usage of arms.
“This kid has thrown the ball really well,” Kotsay said. “He’s earned this opportunity. For us, it’s very similar to [J.T.] Ginn. He can go an inning if need be, but if we need more length, we have it from him.”
