De Aza extended his hitting streak to five games, going 3-for-4 with a triple in Monday night's win over Toronto. De Aza has been a slugging machine over the past two weeks, with nine of 16 hits going for extra bases. What was a non-descript transaction at the beginning of June -- Boston acquired De Aza from Baltimore when it lost outfielders Shane Victorino and Daniel Nava to injury -- has become an expected source of production. With Hanley Ramirez (hand) and Dustin Pedroia (hamstring) both on the way back from injury, De Aza's hold on regular playing time has a short shelf life, but he's a useful piece right now.
