Indians' top pick Zimmer nets RBI single in pro debut

University of San Francisco product goes 1-for-4 for short-season Mahoning Valley

Bradley Zimmer, the Indians' first-round pick in the 2014 First-Year Player Draft, hit an RBI single in his professional debut Monday, but short-season Mahoning Valley lost at Auburn, 4-3, in 10 innings.

Zimmer served as Mahoning Valley's designated hitter and went 1-for-4 with an RBI and two strikeouts. He batted in front of Indians No. 6 prospect Francisco Mejia, who finished the night 2-for-4 with a walk and an RBI.

The Indians selected Zimmer out of the University of San Francisco with the 21st overall pick in the Draft earlier this month. He signed with the club June 17 and officially got his career underway Monday. He grounded out to first base in his first plate appearance before driving in a run with a single in the fourth. He was hit by a pitch in the sixth and struck out in his final two at-bats.

Zimmer hit .368 with seven home runs and 21 stolen bases in 54 games with San Francisco this spring. He became the second first-rounder in his family, joining his older brother, Kyle, who was selected fifth overall by the Royals in 2012.
