Willy Taveras, OF, Houston Astros
Chris Duffy, OF, Pittsburgh Pirates
BJ Upton, 3B/SS, Tampa Bay Devil Rays
Shin-Soo Choo, OF, Cleveland Indians
Jason Repko, OF, LA Dodgers
Maicer Izturis, 3B/SS, LA Angels
Nelson Cruz, OF, Texas Rangers
Esteban German, 2B/3B/OF, Kansas City Royals
Royce Clayton, SS, Cincinnati Reds
Luis Castillo, 2B, Minnesota Twins
Hector Luna, 2B/SS/OF, Cleveland Indians

Obviously, Taveras is the top option, but I'm doubting he's available. The same goes for Upton.
Given your situation, Duffy could be a prime pick-up. He just returned to the lineup on August 1st (had been out since May 14), and in 18 at-bats since, has 3 swipes.
