Bryan Shaw boasts a 1.54 ERA over 18 appearances in his first season for the Indians.
Acquired from the Diamondbacks as a bit player in January's complicated three-team trade, Shaw has been a linchpin in Cleveland's bullpen, compiling a 1.07 WHIP and 23/7 K/BB ratio in 23 1/3 innings. He's only earned two holds, however, and they came in consecutive appearances earlier this month.

Cesar Ramos has allowed runs in his last two appearances.
He took the loss Wednesday in Toronto. Prior to those outings, Ramos hadn't allowed a run in May. He owns a 3.44 ERA, 1.20 WHIP and 12/5 K/BB ratio over 18 1/3 frames, but only one hold in 17 games.

Steve Delabar's first full season in Canada is going swimmingly, as he's 3-1 with a 1.80 ERA and 1.20 WHIP over 25 innings for the Jays.
Acquired from the Mariners for Eric Thames at last year's trade deadline, Delabar has been excellent since he stepped off the plane. The 29-year-old pitched in independent league ball from 2008-09, missed the 2010 season due to an elbow injury and spent most of 2011 in the minors. Delabar's amazing story includes a 3.21 ERA in 98 innings innings since his September 2011 debut.

Ryan Webb has been a steady veteran influence on Miami's bullpen, posting a 2.08 ERA and 0.96 WHIP over 26 innings in 2013.
The bad news, for owners in holds leagues, is that Webb has only one. Such is life for Miami relievers, who inherit leads about as often as deceased investigative reporters.

Chad Durbin sports a hideous 10.38 ERA in May.
His season ERA of 8.10 ain't much better. Durbin sat at a decent 3.52 ERA on April 29. Since that time, he's been a human pinata, allowing 10 runs on 10 hits and four homers over just 3 2/3 innings. Durbin, 35, registered a solid 3.10 ERA in 61 innings last season for the Braves. Philadelphia may be wondering if they purchased a $1.1 million mole at this point.
