Haase will start at catcher and bat eighth in Sunday's game against Atlanta.
Triple-A Sacramento call-up Drew Cavanaugh received the first two starts at catcher following Daniel Susac's (back) placement on the injured list Friday, but Haase could end up being the main beneficiary from a playing-time standpoint while Susac is shelved. Since being promoted from Triple-A on April 21, Haase is batting just .200 but has made his 12 hits count, slugging four home runs and three doubles over 66 plate appearances.
