Pheeling Positive:*Odubel Herrera - he was essentially free (cost only $50K) and he looks to be a useful piece heading forward. He's batting .286/.699 with 11 R, 9 RBI, and 5 stolen bases, having played in every game thus far.
*Freddy Galvis - we knew the defense was decent, but his stick has been great so far. He's batting a lofty .330/.764 while providing a 0.8 WAR.
*Aaron Harang - signed to only a 1 YR/$5M contract makes him quite alluring come the Trade Deadline. Through 6 games started he's posted a 2.35 ERA and 0.97 WHIP, good for a 1.5 WAR.
Feel free to add to the list, in the comments section, if you see fit.
