I guess we could all ask when is Pena going to reheat up, or will he? If not, you're hurting at 1b. I really like Utley and it seems he is carrying your team. You have a few slow starts from some players, which i hope will turn around soon. I say you sit with Aybar until Tulo returns, cause you will have to find room for him, and Aybar has been fine thus far.
I really like your pitching, except for Chris Young, i can't see him turning it around this year. Otherwise its a solid staff, with few young studs like Bucholz and Jurjens. I'm not completely sold on the closers though.
And i agree, using McLouth maybe as trade bait getting Braun would be awesome. He is definately turning things around quick and we know he can have a major hot streak.
