Peterson was designated for assignment Thursday, Jane Lee of MLB.com reports.

Analysis:

The move was made to clear room on the 40-man roster, with the A's picking up Mark Canha from Colorado on Thursday. Peterson had a brief, two-game stint with the A's in 2013, notching an RBI single for his only career major league hit. He spent last season in Triple-A, hitting .308 with 90 RBI and 11 home runs in 543 at-bats.
