Here's a few of my OF targets via trade:
1. Jose Martinez, Cardinals, 1B/RF - I don't like his defense at first or OF, but he isn't worse than Kemp and certainly not worse than Castellanos "who has, over the past two seasons, been baseball's worst defensive player." (quoting MLBTR chat, Steve Adams). I also like that they seem to only want a good lefty bullpen arm in return and this kid isn't making any real money yet so we can make him a bench option if we find another outfielder later.
2. Peralta, OF, D'Backs - Hits righties very well and his struggles vs lefties are no concern since we have Camargo/Duvall to play vs them.
3. Santana, OF, Brewers - Hits righties very well and had a big season just a year ago including 30 homers. Brewers are said to be willing to move an outfielder so depends on the cost.
