The Blue Jays recalled Estrada from Triple-A Buffalo on Monday and optioned him to Triple-A on Tuesday.
In the aftermath of Monday's trade deadline, the Blue Jays were able to reopen a spot on the 26-man active roster and in the bullpen for Estrada. The 27-year-old righty ended up going unused in Monday's 3-1 win over the Astros before being sent back to the minors Tuesday to clear a spot on the roster for right-hander Jose Soriano.
