Brandon Lyon is enjoying his first season in Queens, recording a 3.06 ERA through 21 appearances.
New York guaranteed Lyon less than a million bucks as a free agent this winter, an investment that is paying off nicely. The veteran reliever has five holds, a 1.08 WHIP and 16/4 K/BB ratio in 17 2/3 innings. Lyon registered a solid 3.10 ERA, 1.25 WHIP and 63/20 K/BB ratio across 61 innings last season between the Astros and Blue Jays.
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.
