Eric O’Flaherty Statistics and History – Baseball-Reference.com.

The Mariners tried to sneak a live arm back to the minors last offseason, but the Braves caught them in the act and wound up with one of the better lefthanded relievers in the game. I was critical of O’Flaherty early on, when he had trouble in a couple of early outings, but like Moylan he righted himself. He wound up making 78 appearances with a 3.04 ERA.

The red flag here is his strikeouts; he only struck out 39 in 56 and a third IP. Even for a lefthanded reliever (and O’Flaherty was not used as a pure LOOGY, facing righthanders about half the time) that is a low rate. His components are much better against lefties, and the Braves should seriouly consider limiting his role. But a lot of that is dependent upon someone else stepping up as a fourth righthanded reliever.
