It's been reported by guys like Rosenthal and Olney, among others, that Melvin is targeting infield depth(most likely SS) and relief pitching. I think he'll address both before the deadline. Stetter might be able to help as an extra lefty, as he's close to returning, but we'll see. Roenicke has already shown some improvement lately with bullpen management, and I also think that Hawkins and Saito will be used more in the second half. I think Hawkins has been held back for the second half, which probably isn't a bad idea. If Doug can get another reliever to go along with what we have, I think the bullpen will be very strong in the second half. Also, if he does get a starting SS that the lineup will look a lot better. McGehee will still be in there, but if it's just him and not him and Yuni in there it won't look as bad. Just adding that one piece will strengthen the lineup a lot in my opinion.
