Mariners Breakout Candidate Number #2 Pitcher Bryce Miller

Miller dazzled in the minor leagues last year, posting a 3.16 ERA and 163 strikeouts in 133.2 IP across three different levels of minor league ball. He features a plus fastball which can top out 99 MPH. Miller also mixes in three other pitches a high-70s curveball, a mid-80s changeup, and a slider in the mid-80s. His best secondary pitch is his slider, which he uses to mix speeds and location. The Mariners selected Bryce Miller with the 113th pick in the 2021 MLB Draft in the fourth round out of Texas A&M.

It is unknown whether the Mariners will decide to use Miller as a reliever or a starter. However, considering the depth of the Mariners rotation the likely spot for Miller will be out of the bullpen. Miller could be the next Matt Brash for Seattle since he features both a high-90s fastball and a filthy slider. Bryce Miller has been a name to watch for in Spring Training and he has shown potential with a 2.00 ERA and nine strikeouts in nine innings of work. Keep an eye on Bryce Miller should the Mariners eventually call him up to the big-league roster as a replacement for reliever Erik Swanson.
