Ronald Belisario sits on a 3.22 ERA through 23 appearances.
Belisario put up a nice 2.54 ERA while striking out nearly a batter per inning last season. He's punched out one less batter per nine innings in 2013 and his control hasn't been quite as sharp. Currently, Belisario is allowing the highest batting average, on-base percentage and slugging percentage of his career, but he has been slightly unlucky with balls in play,
Josh Tomlin (Tommy John surgery) could return near the end of the season.
Tomlin went under the knife last August. At this point in his rehab, it's hard to predict if a 2013 return is in the cards. Tomlin has said he'd rather be 100 percent for 2014 rather than making a premature late-season return this year. The right-hander posted a 6.36 ERA in 16 starts and five relief appearances with the Indians last season.
Martin Maldonado has regressed at the plate in 2013, slashing .184/.253/.303 over 83 plate appearances.
In his first real exposure to Major League pitching, Maldonado batted .266/.321/.408 in 256 plate appearances last season. Perhaps he's toting his struggles onto the field with his catcher's gear. Maldonado has been a run worse than average defensively this year, according to Baseball Reference.
