Rangers Prospect Weekly: Dreiling's Scorching August, Perich's Power Surge at Frisco
By Noah Patterson ·
Rangers Prospect Weekly covers the last 7 days of action for the Rangers farm system.
The Bar Has Been Cleared: Dylan Dreiling Is Doing Something Real
Dylan Dreiling (AA, OF, Rank: 16) went 12-for-24 with a double, three home runs, and six RBI this week at Frisco, pushing his season total to 21 home runs in 98 games. That number alone marks a significant step forward for a hitter who posted 12 homers in 110 games at High-A a year ago, but what makes the current run harder to dismiss is the quality of contact sustaining it. Over the last 30 days, Dreiling is slashing .388/.453/.753 with eight home runs, seven doubles, and 21 RBI across 21 games, an 83.4 contact rate that shows he is not selling out for damage. The swing rate has nudged up to 48 percent this month, which is not an alarm but does suggest he is being more aggressive against strikes, the exact adjustment that the passive-approach concern in his profile called for.
The scouting picture on Dreiling is a 50 hit, 50 power left fielder with a second-division ceiling, and that read is not wrong as a framework. But the 2026 production is testing its upper limits. A .310/.383/.533 full-season line at Double-A, combined with a contact rate that has held steady across two seasons at the same 80.5 percent mark, means the gains are not built on lucky variance. The arm and range still project as below average in a corner, so the bat has to be the conversation, and right now it absolutely is. A September promotion to Round Rock feels overdue, and if Dreiling carries even a version of this August into Triple-A, a legitimate big-league discussion follows shortly after.
Rafe Perich Is Hitting His Way Out of the Projection
Rafe Perich (AA, 3B, Rank: 28) had the week of any hitter in the system, going 10-for-23 with four doubles, two home runs, and six RBI while walking twice against four strikeouts. The production is not a one-week flash. Over the last 30 days at Frisco, he is hitting .307/.354/.545 with four home runs and nine doubles, and the full combined season line across High-A and Double-A sits at .306/.390/.595 with 25 home runs, 28 doubles, and 79 RBI in 101 games. For context, Perich hit six total home runs in 96 games across both levels a year ago. The jump to 25 is not a rounding error. His contact rate of 75.7 percent is not a strength, but the switch-hitting ability and the willingness to take walks, 50 free passes on the season, give him enough floor that the power can function as the carrying tool it needs to be.
A 45 hit, 50 power profile projecting as a bench piece at first base is the current read, and the defensive picture at third base has not changed much. But the offensive output is pulling ahead of those grades, and a Texas League Player of the Week award back in July was not a ceiling moment. The swing can get steep and lean on lift rather than line drives, which leaves him exposed to quality velocity, and Double-A arms will continue to probe that. Still, 25 home runs as a 24-year-old who spent last year as a fringe prospect is a resume line that earns a legitimate Triple-A look. If the power holds at Round Rock, the bench projection starts to feel conservative.
Quick Hits
- David Davalillo (AAA, RHP, Rank: 6) · was the best pitcher in the system this week, tossing 11.1 innings with eight hits, two earned runs, one walk, and nine strikeouts. The outing pushed his last-30-day ERA at Triple-A to 2.67 across 27 innings with 23 strikeouts and just four walks, a stretch that looks nothing like the 5.36 ERA he carried into late July at Round Rock. The stuff has always been there: a 94-96 mph four-seamer and a 50-grade slider that sequences well when the command is working. His full-season ERA across levels sits at 4.61, but the last six starts suggest a pitcher who has found something mechanically. The Quad-A projection is reasonable given the command volatility, but outings like this one make it harder to dismiss him as a rotation option.
- Cam Cauley (AAA, SS, Rank: 14) · was optioned back to Round Rock on August 14 after a 28-game MLB stint, then went 6-for-21 with two home runs and six RBI in his first week back at Triple-A. His MLB line of .207/.281/.345 was modest but showed the speed that makes him interesting: 32 stolen bases on the Triple-A season and a 65 speed grade are real tools even when the bat is finding its footing. The up-down utility role fits him, and the two homers this week are a reminder that the 40 power grade may be selling him short in stretches.
- Elian Rosario (RK, SS, Rank: 20) · drove in seven runs in 19 plate appearances, adding two home runs and a double across the week. He is 17 years old with a 60 power grade and projections toward an everyday right field role, and the 54 RBI in 222 plate appearances this season at the complex level reflect how much damage he can create even against a swing-and-miss concern. A 63.5 percent contact rate and 56.1 percent swing rate point to the volatility, but the upside here is as loud as anyone in the lower levels of this system.
- Deward Tovar (A, OF, Rank: 21) · had six hits in 22 plate appearances with two doubles, a home run, and seven RBI, adding four walks against three strikeouts. Over the last 30 days he is posting a .375 on-base percentage with 16 RBI in 20 games, a stretch that shows the approach can tighten when he is right. The 112 strikeouts in 377 plate appearances this season and a 64.2 percent contact rate remain the defining concern for a 20-year-old with a 55 power grade, but weeks like this one show the offensive floor is higher than the season average suggests.
- Yolfran Castillo (A, SS, Rank: 11) · went 7-for-23 with a double and three walks against five strikeouts. The 51 stolen bases on the season lead the system and reflect a player who impacts games without needing the power to carry him. A 55 hit grade and 55 field grade give him a legitimate shortstop baseline, and the .386 OBP for the season shows the zone discipline is genuine. I would take the over on his up-down projection if the contact quality keeps trending.
- Aidan Curry (AA, RHP, Rank: 30) · had an eventful week: promoted to Triple-A on August 15, delivered five innings of one-run ball with two hits, a walk, and three strikeouts in his AAA debut, then was sent back to Frisco the following day. The brief cup of coffee still showed his best tool, a 34.6 percent whiff rate on the season that ranks among the better miss-bat numbers in the system. Over his last four starts at Double-A he owns a 2.29 ERA with 19 strikeouts across 19.2 innings, which is what earned the call in the first place. The fastball-slider combination is good enough to play up in shorter stints, and the reliever projection might actually serve him better than stretching him as a starter.
- Josh Owens (A, TWP, Rank: 7) · was promoted from the ACL to Hickory on August 18, his first assignment to full-season ball. He posted a 3.48 ERA with 24 strikeouts against seven walks across 20.2 innings at the complex level, which is an efficient foundation that earns a promotion. As a two-way player, the development path is non-linear, but the arm is clearly ahead of schedule.
- Seong-Jun Kim (A, SS, Rank: 22) · was promoted from the ACL to Hickory on August 19 after posting a .303/.419/.545 line with seven home runs and eight stolen bases in 160 plate appearances at the complex level. The switch to full-season ball is the next real test for a 19-year-old shortstop who has handled the lower level with room to spare.
- Enrique Segura (A+, RHP, Rank: 43) · struck out six batters in three innings but allowed one earned run on one hit and three walks. The week-level results are better than the season tells: a 7.07 ERA, 45 walks, and 15 home runs allowed in 62.1 innings at High-A reflect reality. The fastball touches 96 mph and the slider flashes plus, but neither plays consistently when the command is this erratic. A move to the bullpen, where effort and command variability matter less, may be the conversation the organization needs to have.
