TORONTO -- The Chicago Cubs have reinstated catcher Miguel Amaya and right-hander Javier Assad from the 60-day injured list.
Chicago also optioned right-hander Nate Pearson to Triple-A Iowa and designated infielder Jon Berti for assignment in moves announced before Tuesday's game at Toronto.
Assad was slated to start the series opener against the AL East-leading Blue Jays.
The 26-year-old Amaya had been on the injured list since May 25 with a left oblique strain. He hit .280 with four homers and 25 RBIs in 27 games prior to the injury.
