As of this writing, Shane Bieber is the top arm for the Guardians, and the second most famous Bieber.

Debuting for Cleveland in 2018, two years after he was drafted (4^th Round), Bieber was 11-5 as a rookie, though his ERA was 4.55.  He shaved more than a run off his ERA as a sophomore (3.28), and added a first All-Star while going 15-8 and fanning 259 batters. 

Bieber’s best year to date was in the COVID-shortened 2020, where he won the Cy Young, and won the Pitcher’s Triple Crown (8 Wins, 1.63 ERA & 122 SO) and was also the league-leader in ERA+ (273), FIP (2.07), H/9 (5.4) and SO/9 (14.2).  Since then, he added an All-Star in 2021, a Gold Glove in 2022, and he enters 2024 well under 30.
