The Yankees announced on Monday that right-handed reliever Bryan Mitchell was optioned back down to Double-A Trenton, a day after being called up for Sunday's game against the Tampa Bay Rays at the Trop.
The move was likely to make room on the 25-man roster for David Robertson, who is expected to be activated off the 15-day DL tomorrow in Boston.
Like Shane Greene a couple times this season, Mitchell was optioned back to the minors without getting to throw an actual pitch for the big league club. He was warming up in the 12th inning of Sunday's win over Tampa, and probably would have come into the game if another inning was needed, or if Preston Claiborne ran into trouble.
So pretty much, Mitchell was only brought up as a last report for a Yankees bullpen that had already put in a lot of work over throughout the four-game series.
The Yankees also announced this afternoon that reliever Matt Daley was optioned to Triple-A Scranton, clearing waivers after he was designated for assignment on Sunday.
