2023 Top 100 Prospects Breakout Candidate: Righthander Bryce Miller

When the Mariners drafted Bryce Miller in the fourth round of the 2021 draft, it was the fourth time the righthander had been eligible for the draft. 

Unselected in the 2020 draft, Miller headed back to Texas A&M. There Miller had a strong season but bullpen questions persisted. 

He debuted following the 2021 draft, tossing 9.1 unspectacular innings for Modesto.

Long a data darling due to his combination of a low-launch and a hop-heavy fastball with premium velocity, Miller generated significant buzz late in the offseason when video of him hitting 100 mph surfaced on social media. 

While he may have seemed like just another hard thrower with a relief future, what transpired over the months that followed solidified Miller as one of the best pitching prospects in the game. Miller combines elite stuff with above-average command, as his fastball, slider and changeup all grade out as plus pitches on Stuf+ models. 

His fastball sits 95-97 mph, touching 100 mph at peak with excellent vertical movement. His slider is a mid-80s sweeper that generates a high rate of chase swings out of the zone, playing well off of his fastball. His changeup is rarely used but has performed well in limited usage. 

Coming off of a strong 2022 where Miller went 7-4 over 26 starts, while striking out 163 batters over 133.2 innings, he enters 2023 ready to make his big league debut.
