21 roster spots in total (+2 DL) with 1 per infield position, 3 OF, 1 UT, 2 SP, 2 RP, and 3 P spots

C - Brian McCann
1B - Joey Votto
2B - Martin Prado (1B, 3B eligibility)
SS - Erick Aybar (Reyes coming off DL)
3B - Evan Longoria
OF - Shane Victorino
OF - Curtis Granderson
OF - Carlos Quentin
UT - Jay Bruce
BN - Jorge Cantu (1B, 3B)

Steals and saves are clear weaknesses, and I'm a bit worried Bruce, Quentin, and Granderson will hurt my average.
I'm trying to deal one of my waiver pick-ups (Marcum, Wilson) for a lower-tier closer like Chris Perez. Any suggestions would be much appreciated.
