Get Ian Kinsler (2B-SS), TEX if he is available. He will be a solid short term upgrade over Rollins, and a reasonable long-term play. Forget about Gomez, he's hurt-injured. His shoulder is so bad it requires surgery (an admitted fact), but he's trying to play through it without much success. I would try to deal Prior if a reasonable deal comes up; for this year anyway, he's a mid-level at best starter. I hope Ozuna is not your long-term play at OF...Guys to look for: Ibanez, Shawn Green, MARCUS THAMES...sorry brain fart, I cant come up with others...
As for the bullpen (in order of quality), Joel Zumaya, Jorge Julio, the KC closer (burgos, i think), Jorge Sosa. Zumaya is a set up guy, but he has a fair chance of winning the job soon. He throws 100 MPH and gets good SO/IP.
Hope that helps.
