Jay Bruce or Gaby Sanchez!!!?

Who would you rather have for the 2nd Half? I currently have Jay Bruce. Which one do you think will have the more productive 2nd half? I could really use a hitter that can boost my average in my league. I have power hitters like Ortiz, Aramis and Manny Ramirez, Quentin, Mark Reynolds, and Josh Hamilton. Thanks for any help!!!
