Seattle Mariners top prospect has electric stuff and dazzles in his MLB debut:Strikes out 10 batters and he has an 87 mph “nasty/sick” changeup

Mariners top pitching prospect shows off electric stuff in dazzling debut

Bryce Miller made his major league debut Tuesday evening in Oakland, and he looked like a seasoned vet carving up the Athletics lineup.

Striking out 10 batters and walking zero, he joined Stephen Strasburg and Johnny Cueto as the only pitchers to accomplish that in his debut. Miller was able to mix speeds to get hitters to chase and then would finish them off with his fastball.

“Obviously the stage was bigger, but I think the atmosphere kind of helped me ease into it,” Miller told Adam Jude of The Seattle Times. “I threw a lot of fastballs, and they weren’t hitting them. So I kept throwing ’em.”

A 2021 4th-round pick out of Texas A&M, Miller had made four starts in Double-A before getting called up. He struggled in those starts, allowing 14 runs in 19 2/3 innings for a 6.41 ERA. But that didn’t stop the Mariners from giving him a shot.

With a glimpse of his electric fastball and nasty movement on his secondary pitches, it’s no wonder why he is the 88th overall prospect in baseball and a player Mariners fans have been excited for since spring training.

While this start was memorable, it was against the Athletics, who are off to a historically bad start in 2023. Miller is slated to make his next start at home against the Houston Astros, who will offer up a big challenge for the 24-year-old.
