The Oakland Athletics reinstated outfielder Craig Gentry from the 15-day disabled list and optioned right-handed pitcher Dan Otero to Triple-A Sacramento on Friday.
Gentry was placed on the 15-day disabled list July 28 with a broken right hand. He began a two-game rehab assignment with Sacramento on Monday against Oklahoma City and went 0-for-7 with an RBI and three strikeouts in starts at designated hitter and in right field.
Gentry was 4-for-29 over his final 12 games with the A's before the injury and is batting .264 with 18 stolen bases in 19 attempts in 80 games overall.
Otero has spent the entire season with the A's and is 7-1 with a save and a 2.28 ERA in 56 relief appearances.
