Cal Poly relief pitcher Michael Holback signed with the St. Louis Cardinals, the team announced on Tuesday, ending speculation that the junior right-hander could return to San Luis Obispo for his senior season.
Holback was selected by St. Louis in the 25th round, 755th overall in the MLB Draft earlier this month.
Armed with a low-90s fastball, Holback was 3-2 with a 3.86 ERA this past season, helping Cal Poly make just its second postseason trip in Division I program history.
He lost his redshirt season by playing with the club team on campus in 2011 and pitched the past two seasons for the Mustangs, becoming their most reliable long reliever.
Cal Poly has two more players yet to sign professionally that could come back to school for next season.
Sophomore closer Reed Reilly was taken in the 18th round, 549th overall by the Baltimore Orioles, and third baseman Jimmy Allen was taken in the 23rd round, 683rd overall, by the Boston Red Sox. Reilly told The Tribune he was 90 percent sure of returning after he fell out of the top 10 rounds.
