Bradford is the owner of a funky delivery chronicled in Moneyball. He's not a strikeout pitcher (only 2.90 K/9 this season) however he doesn't walk anyone either and gets an amazing amount of groundballs (nearly 70%) which makes him a nice fit for the Rays infield defense. He's also the owner of a sub-4 FIP and a 2.64 BERA.
Bradford is only 33 and is under contract through next season at 3.5 million.
