He’s 2023 all-star Mitch Keller, and he’s currently employed by the Pittsburgh Pirates. He made his major league debut in 2019 and has been with the big league club since then, outside of a brief demotion in 2021.
Is he any good?
I truly don’t know how to answer that question. When he was coming through the minor leagues, he was a top prospect, throwing 99 MPH fastballs, racking up strikeouts, and posting great numbers at every level. When he got the call to the majors in 2019, he struggled, lost his confidence, and looked like a bust.
