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.

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.

Bastardo has also blown two saves. He's punching out 4.6 less hitters per nine innings then he did last year, when he had a poor 4.33 ERA, and he's allowing more hits and walks. If Bastardo doesn't become stingier with base runners, his peripherals will begin to wreak havoc on his ERA.

Clippard is seventh in the National League with eight holds. He's collected three wins in 2013 and posted a 2.50 ERA, 1.00 WHIP and 19/11 K/BB ratio over 19 appearances. The Yankee Clippard had a 6.33 ERA over six starts in the Bronx as a rookie in 2007. In the six years since, he owns a sparkling 2.83 ERA and 1.09 WHIP for the Nationals. It's time for a new nickname, though The National Clippard leaves plenty to be desired.
