Rangers Prospect Weekly: Perich Keeps Raking, Cauley's Power Surge at Round Rock
By Noah Patterson ·
Rangers Prospect Weekly covers the last 7 days of action for the Rangers farm system.
Rafe Perich Keeps Hitting at Frisco
Rafe Perich (AA, 3B, Rank: 24) went 6-for-14 with a double, a home run, and four RBI this week at Frisco, including a pair of RBI singles on August 23 and his 15th homer of the Double-A season on August 26. The home run, which also scored Dylan Dreiling, was a run-creating moment that has become routine for him over the past month. Over his last 30 days at Double-A, Perich is slashing .397/.455/.692 with five home runs, eight doubles, and 18 RBI across 21 games. The contact rate over that stretch sits at 77.6 percent, which is not a dramatic departure from his season norm but is holding well enough to keep the damage production from looking like a pure exit-velocity fluke.
The scouting picture on Perich is a 45 hit, 50 power switch hitter projecting as a bench piece at first base, and the defensive limitations at third are real enough that the bat has to do the work. It absolutely is. His combined season line across High-A and Double-A stands at .313/.398/.604 with 26 home runs, 29 doubles, and 83 RBI in 104 games, a leap from a .231/.347/.330 line with six homers over 96 games a year ago. His swing rate has ticked up to 47.8 percent over the last 30 days, consistent with the more aggressive approach against strikes that his profile calls for, and his 11.4 percent walk rate at Frisco shows he has not abandoned zone control to get there. The bench projection is still reasonable given the defensive picture, but a full season of this offense in Double-A earns a legitimate Triple-A look, and if the bat holds at Round Rock, the conversation shifts accordingly.
Cam Cauley Goes Deep Three Times at Round Rock
Cam Cauley (AAA, SS, Rank: 14) had the most power-concentrated week of his career, going 9-for-28 with three doubles, three home runs, and five RBI across his plate appearances at Round Rock. The three-homer week is worth sitting with for a player whose rank projects him as a 40 power, speed-and-defense utility type. Over the last 30 days at Triple-A, Cauley is slashing .273/.319/.561 with five home runs in 21 games, and his season line at Round Rock sits at .272/.366/.452 with 13 home runs through 84 games. That is a different offensive profile than his 2025 Double-A campaign suggested, where he posted 15 homers across 113 games but with more contact-driven production and less raw over-the-fence output.
The tension in Cauley's profile is real. He is a 65-grade runner with a 55 glove who projects best as a utility piece or up-and-down infielder, and the hit tool grades at 45 with some swing-and-miss risk when pitchers work him with quality velocity. His contact rate at Triple-A this season is 72.7 percent over the last 30 days, and the 35 stolen bases on the season remain the clearest statement of what he brings to a roster. But the power number is making a case of its own. He has already matched his 2025 Double-A home run total in fewer games at a tougher level, and his 12.5 percent walk rate at Round Rock on the season is the best of his career. Whether the pop is a function of a mechanical shift or a favorable environment is worth watching, but three homers in seven days at Triple-A earns the right to ask the question. He has already appeared in 28 games at the big league level this season and posted modest numbers, and a sustained power run at Round Rock could push him back into that conversation sooner than expected.
Quick Hits
Dylan Dreiling (AA, OF, Rank: 16) · drove in four runs on nine hits in 25 plate appearances this week, adding a double and posting his cleanest contact week in a month. His last-30-day line at Double-A reads .407/.453/.686 with six home runs and 20 RBI across 20 games, and the full season sits at .314/.384/.528 with 21 homers in 103 games. The contact rate over the last 30 days is holding at 82 percent, the best in the system among regulars, and the swing rate of 49.2 percent shows he is engaging rather than drifting into passive counts. A second-division left field ceiling is still the framework, but he is running out of things left to prove at Frisco.
Maxton Martin (A+, OF, Rank: 34) · had a three-homer week at Hickory, going 7-for-22 with seven RBI and a walk. The power has been real over the last month: seven home runs in 23 games with a .549 slugging percentage over the last 30 days. His season total sits at 20 home runs in 107 games, already six more than he hit across the full 2025 season at two levels. The problem is the rest of the line. His swing rate of 59.5 percent over the last 30 days is aggressive even by High-A standards, and the contact rate of 68 percent creates real exposure against pitchers who can locate velocity. He projects as an organizational depth piece with some pop, and the home run total is keeping that ceiling alive for now.
Sebastian Walcott (AA, SS, Rank: 1) · was on base eight times in 25 plate appearances this week, drawing six walks and collecting six hits with a pair of doubles. He did not drive a run in, but the zone discipline was notable: a 13.5 percent walk rate over the last 30 days at Frisco is the kind of selective approach that lets his bat speed and athleticism play without forcing the issue. His Double-A season line stands at .290/.377/.490 with 11 doubles and three home runs in 25 games, a 20-year-old holding his own against older arms. The swing-and-miss is still the central concern at 71.1 percent contact on the season, and advanced breaking balls will keep probing it.
Josh Trentadue (AA, LHP, Rank: 28) · was at his best in five innings of two-hit, scoreless ball this week, striking out six and walking one against 19 batters faced. He generated 11 swinging misses on 79 pitches, a strong rate for a starter who profiles as a long reliever. The season ERA at Frisco sits at 5.73 across 66 innings, so one good outing does not erase the context, but his 27.7 percent strikeout rate on the season shows the bat-missing ability is real when the fastball stays honest. The command story, a 40 grade with a 10.5 percent walk rate, is the gap between what this week looked like and what he does regularly.
Dalton Pence (AAA, LHP, Rank: 25) · delivered four scoreless innings on two hits with two strikeouts and two walks in his start this week. His season ERA across all three levels sits at 2.72 through 99-plus innings, with the Round Rock number checking in at 2.75 over five starts. A 55-grade fastball from the left side and a three-pitch mix that includes a plus-projecting slider and splitter-type changeup give him legitimate late-inning or multi-inning ceiling. The walk rate at Triple-A is a touch elevated at 9.6 percent, but the body of work across levels this year is the most consistent pitching performance in the Rangers system.
Yolfran Castillo (A, SS, Rank: 12) · went 3-for-13 with a home run and two RBI across a short week at Hickory, also drawing a walk and avoiding a strikeout in 13 plate appearances. He has 51 stolen bases on the season across 113 games, with a 13.0 percent walk rate and only a 14.2 percent strikeout rate that ranks as one of the better contact profiles in the Low-A Carolina League. A 55 hit tool with plus shortstop defense at 19 years old is a legitimate foundation, and his brief High-A appearance late in the week may signal the org is ready to push him.
Ismael Agreda (A+, RHP, Rank: 39) · put together six innings of two-hit, one-run ball at Hickory this week, striking out six while walking one. The 34.8 percent whiff rate on the season is his clearest asset and it showed up here with 16 swinging misses on 86 pitches. The season ERA at 5.60 tells the fuller story: a 13.0 percent walk rate that undermines a mid-90s four-seamer and a breaking ball with genuine swing-and-miss. When the command shows up, as it did this week, the package looks like a late-innings arm with a shot to stick. Getting there consistently is the project.
Malcolm Moore (AA, C, Rank: 13) · put together a productive 10-plate-appearance week, going 4-for-10 with two doubles, a homer, and two RBI. His Double-A season line sits at .219/.308/.411 with seven home runs and a 25.6 percent strikeout rate, a clear step back from the .300/.387/.542 he posted at High-A earlier this year. The 60 power grade is real and the left-handed pop plays when he gets to his launch, but the contact rate at Double-A and an aggressive 55.8 percent swing rate over the last 30 days point to a hitter still sorting out how advanced arms sequence against him. Weeks like this one are the reminder of the everyday ceiling.
Deward Tovar (A, OF, Rank: 22) · drove in three on four hits in 18 plate appearances, adding a homer and a double. Over his last 30 days at Hickory he is hitting .288 with three home runs, 17 RBI, and a 16.4 percent walk rate across 20 games. The walk rate improvement is meaningful given the swing-and-miss concern that defines his profile; a 63.9 percent contact rate on the season is still a genuine red flag, but the added patience gives the power a better platform. Sixteen home runs in 102 games at Low-A for a 20-year-old keeps the 55 power grade looking right.
Winston Santos (AAA, RHP, Rank: 11) · went 5.2 innings against 24 batters this week, allowing two hits and one earned run while striking out seven and walking four. The four walks fit a season-long pattern: a 10.5 percent walk rate at Triple-A and a 45-grade command mark that limits what an otherwise usable starter arsenal can do. The fastball reaches 97 and the changeup is the best secondary in the group, genuinely capable of missing bats against lefties. His season ERA across all levels sits at 7.21, though the Round Rock results alone at 6.75 show this has been a rough year. He profiles as a back-end starter or swingman if the command margin widens, but the recent form is not pointing that direction.
