Mesoraco (hip) was placed on the 10-day disabled list Sunday.
The DL placement is retroactive to Mar. 30, but it remains possible that Mesoraco may not be ready to return to live action when he's eligible to come off of the disabled list. The 28-year-old is expected to begin the season in extended spring training in order to receive regular at-bats. Tucker Barnhart will fill the starting catcher role in Mesoraco's absence.
