Looks like things have stabilized in the bullpen now that Voth has gone, Arano is on the IL, and there is a 13 man limit on the pitching staff.
There's a primary 5 - Rainey, Edwards, Finnegan, Cishek, and Erasmo - that are higher leverage, tied, and close trailing middle inning guys.
Then there is a shuffle / shuttle of guys with options in the 6-8 slots that are used to mop up innings in blow outs, pitch early when the starters don't go deep, and are otherwise used when behind. Right now, that's Claytus, Machado, and Reed Garrett on the active roster, and Abbott, Weems, and Perez in Rochester. All of these guys are more or less on the roster because they have options and can take punishment. Perez and Claytus are interchangeable lefties, while Abbott, Weems, Garrett, and Machado are righties. I guess Machado is slightly ahead of Abbott, Weems, and Garrett in terms of leverage.
Garrett went to VMI and was born in Henrico - not sure if it was the fashionable west end. It looks like he's been used less because of the lack of starters being lifted early. Garrett and Weems (and Machado) seem to be guys who have been flushed out of other organizations who are being given shots here. I think they are placeholders for Hunter Harvey, Mason Thompson, and Hunter Harvey.
