J.C. was horrible in '06 but bounced back well in '07. He held his own in Boston even though the Red Sox released him. Philly picked him up and he really did well. He is a former Twin and from the stats.. he shows he may be able to handle the NL better though only a very small portion that I'm basing that off of (36.1 innings). His stats for 2007:
2-2 1 Save 1.92 ERA 74 Games 56.1 Innings 40 BB 42 K
The walks stand out.. but I think Pole could work on his command.
He might be a good 7th inning guy to go with Burton and Weathers at the end of games.
