Erwin is a 28-year-old left-handed pitcher from Georgia. Coming out of high school, Erwin was drafted by the Minnesota Twins, but he elected to go to Kennesaw State. As a member of the Owls, he served as a two-way player and was named to the Atlantic Sun Conference All-Freshman Team.  

In 2019, the lefty signed his first professional contract and split time between the Sussex County Miners and the Florence Freedom. 2021 was his first year with the RailCats, and he finished with 14 appearances and a 3.10 ERA.   

In last year’s campaign, Erwin was recognized as the Pointstreak Pitcher of the Week after he pitched six scoreless innings with 11 strikeouts in a start against the Lake Country DockHounds.  

In his first three years with the team, Erwin appeared in 47 contests, starting 36, accumulating 189.1 innings, striking out 186, and having a solid 3.90 ERA.
