Infielder Shawn O'Malley has been activated and the Biscuits have released infielder Cody Cipriano.
O'Malley missed virtually all of last season with a shoulder injury and has been in Tampa Bay's extended spring rehab program. Cipriano, who requested his release, had missed 16 of Montgomery's last 18 games due to ankle and hamstring injuries. He was hitting .186 in 14 games. Cipriano was also limited by injuries last year and hit .275 in 71 games.
