Weekly Risers: Bremner's Changeup Is Already a Major-League Pitch at Double-A
By Riley Thompson ·
Tyler Bremner posted a 3.32 ERA across four Double-A starts in his last 30 days, striking out 27 batters against 8 walks in 19 innings, with a whiff rate of 33.1 percent. Those numbers represent a legitimate strikeout-heavy starter's profile at the Double-A level, and they come from a 22-year-old with an occasional __-grade changeup, a fastball that touches 98 mph, and a carrying projection toward the front of a rotation. The Angels promoted him from High-A Tri-City to Rocket City on August 4, and his September has been the clearest evidence yet that the stuff translates under the lights at the Southern League level.
Bremner came out of UC Santa Barbara with a track record that translated directly to his professional profile: high strikeout rates, low walk totals, and a three-pitch arsenal anchored by elite arm speed. The college foundation matters here because it accelerated his timeline considerably. He reached full-season ball quickly and spent the first extended portion of 2026 at High-A Tri-City, posting a 31.4 K% across 14 starts before the Angels decided he was ready for the jump. That promotion came in early August, less than two full months before his first postseason opportunity at the Double-A level.
The physical profile fits a rotation starter. He's lean and long-limbed, with room to add upper-body strength without compromising the mobility that drives his delivery. His three-quarters arm slot is loose and clean, and the delivery is repeatable enough that the organization has been comfortable stretching him into a full starter's workload. No notable injury history has surfaced, which is meaningful for a pitching prospect being pushed through the system at this pace. The body type projects to hold innings as he matures, and professional conditioning should help him maintain top-range velocity deeper into starts.
The headline tool is a mid-80s changeup that grades 70, a genuine plus-plus offering with late fade, excellent velocity separation from the fastball, and the arm speed to keep hitters honest. It finishes below the zone or on the edges consistently, generating both swings and misses and weak ground contact. His willingness to throw it to both left-handed and right-handed hitters in any count reflects real pitchability, not just a weapon reserved for favorable counts against opposite-side bats.
The fastball sits 95-98 mph and grades 60 as a four-seamer, with ride at the top of the zone and enough armside run to miss barrels when he works east-west. The two-seamer grades 55 at 95 mph and adds a different shape that widens the gap hitters have to cover. The combination of a riding four-seamer and a diving changeup at similar arm speed is a legitimately difficult equation for hitters to solve, and the 2026 combined whiff rate of 31.7 percent across 304 batters faced confirms the miss rate is real and sustained rather than a product of soft competition at a single level.
The slider grades 55 at 85 mph and is the variable in the mix. When the shape is sharp, it gives Bremner a third distinct look that completes the arsenal and gives him a breaking ball to attack same-side hitters or bury against left-handed bats when he needs a swing-and-miss out of the zone. The concern is consistency: the slider can lose bite and back up, and when it leaks to the middle of the zone, hard contact follows. His 8 home runs allowed in 72.2 combined innings are at least partly a slider shape issue, and sharpening that pitch will determine how much he can limit damage against hitters who wait out the fastball/changeup combination.
The full 2026 line across High-A and Double-A covers 19 starts and 72.2 innings: a 4.33 ERA, 1.27 WHIP, 8.9 BB%, and 32.9 K% against 304 batters faced. The ERA is inflated by some slider volatility and an efficiency number worth watching; at 20 pitches per inning, he is working through counts rather than dominating early, and anything above 18 pitches per inning represents real inefficiency for a pitcher projecting to log deep starts in a rotation.
The split between levels is instructive. At High-A, the line read 4.28 ERA, 1.34 WHIP, and 9.3 BB% across 14 starts and 48.1 innings. At Double-A, the ERA of 4.44 is almost identical, but the WHIP drops to 1.11 and the K% jumps from 31.4 to 36.0. That divergence is uncommon and suggests the stuff plays at lease as well at the higher level rather than down. This is not what you expect from a pitcher making a mid-season climb. The changeup generates even more swing-and-miss against more sophisticated Double-A lineups, likely because hitters are more aggressive and the pitch's late action punishes early commitment.
The last 30 days sharpen that picture further. Four Double-A starts, 19 innings, 27 strikeouts, 8 walks, a 35.5 K%, a 33.1 whiff rate, and a 3.32 ERA. The BB% climbed to 10.5 in that window, which is a number to track; it sits above his season average and represents the clearest pass/fail marker for sustained Double-A success. He can miss bats at this level, but the pitch economy and walk rate will determine whether he can consistently navigate lineups a third time through and project as a true rotation starter rather than a power reliever riding the fastball/changeup pairing.
The handedness splits across 2026 are about as clean as a pitcher can ask for. Against left-handed hitters, Bremner has held opponents to a .237 average with 4 home runs, 13 walks, and 47 strikeouts. Against right-handed hitters, the average drops to .234, with the same 4 home runs allowed, 14 walks, and 53 strikeouts. The contact rates are nearly identical, the home run rate is even, and the walk volume is distributed evenly across both matchups. There is no exploitable platoon split here; neither side of the plate has found a meaningful edge against his arsenal.
That balance is largely the product of the changeup. By throwing it confidently to both left-handed and right-handed hitters in any count, Bremner neutralizes the platoon dynamics that challenge most pitchers. Right-handed hitters who would typically sit on a four-seamer from a right-hander have to respect the changeup, and left-handed hitters who might otherwise look to extend arms against righties get a pitch that runs away from the barrel. The result is a pitcher who attacks both sides of the plate without leaning on the slider for platoon coverage, which is significant given how inconsistently that pitch has graded this year.
The projection is a number-two starter, with an all-star outcome in the conversation if the full profile comes together. The carrying tools to get there are already present: a 60-grade fastball with ride and run, a genuine plus-plus changeup that plays against both platoon sides, and a 55 command grade with room to grow. The AL Futures Game selection in July reflects organizational and industry conviction in that ceiling.
The pass/fail markers at Double-A are specific. The walk rate needs to stabilize below 9 percent to project a starter's workload deep into games; the 10.5 BB% in September is a warning sign, even in a four-start window where the strikeout volume is excellent. The pitch efficiency number of 20 per inning is a real constraint on how deep he can work, and bringing that closer to 17-18 will require either sharper early-count fastball command or more frequent first-pitch strikes. The slider consistency is the third variable: if the shape stagnates through a full Double-A season and Bremner is left with two primary pitches, hitters will eventually sit changeup and force him to win with fastball location alone.
If the slider refines into a reliable third offering and the walk rate returns to the 8-9 percent range he posted across the full season, the rotation projection holds at the number-two level or better. If the breaking ball remains inconsistent and the walks trend upward, the floor is a high-leverage reliever who can post plus strikeout rates leveraging the fastball and changeup out of a shorter outing. Either outcome is useful, but the stuff and the age support chasing the starter ceiling through a full 2027 Double-A campaign before drawing any firm conclusions about role.
