Chad Orvella has a 1.80 ERA in five innings at Triple-A Durham.
Interestingly, he isn't be used as a closer there, but rather as a setup man. Assuming his mechanics aren't a huge mess Orvella is without question one of the Devil Rays' top relievers, and with the bullpen's struggles early on he could be back soon.

Dan Miceli blew the save and took the loss after giving up three runs in the ninth against the Orioles on Thursday night.
Miceli entered with two outs in the eighth and struck out Kevin Millar with two men on to protect a one-run lead. The Rays added a run in the bottom of the eighth, but that wasn't enough for Miceli, who gave up a walk, a single, a sac fly and a two-run homer to Melvin Mora. Let this serve as a reminder of why Chad Orvella still has fantasy value. Miceli isn't going to lose his job right now, but he's not an above average reliever.

Could have some implications for those with the Tampa Bay closer as (hopefully) their third save man. The Rays can use all the help they can get, and hopefully Orvella will stay healthy. Meanwhile, Miceli needs to stop screwing my fantasy baseball team.
