Id look into getting guys like:
SP(if Tavarez shits the bed and Lester isnt ready to come back)
Buehrle (3.66 ERA, 1.02 WHIP, 1.21 GO/AO, 3.29 K/BB)
Joe Kennedy (3.62 ERA, 1.37 WHIP, 1.69 GO/AO, .91 K/BB)
livan hernandez (3.58 ERA, 1.47 WHIP, 1.13 GO/AO, 1.06 K/BB)
many other options will probably be available by the deadline
CF(Crisp sucks and has proven he can't play in this city)
Rowand (.321, .393 .500, 3 SB, 7 HR)
Byrnes (.306, .366, .519, 9 SB, 8 HR)
Hunter (.318, .359, ..578, 9 SB, 11 HR)
RP(can never have enough bullpen depth, especially if Timlin cant come back strong)
Linebrink (2.19 ERA, .89 WHIP, 1.27 GO/AO, 2.55 K/BB)
Gordon?? (injured all year but has a good track record)
bunch of little pickups available to at the deadline im sure but for now i cant really think of any more big name relievers available
the rest of the roster should stay set, the only other move i could see happening is getting a RH bat (return of Shea maybe??) for the bench if we use Willy Mo in a deal
