Answer: John Rocker
John Rocker began his MLB career at age 23 in 1998. During his time with the Braves, he posted a 2.63 ERA in 195.1 innings pitched while striking out 259.
Rocker’s command was not the best as he walked 123 hitters in those 195.1 innings in an Atlanta uniform. A lot of Braves fans have mixed feelings about Rocker but overall his numbers are probably better than most remember.
