While Arizona's scouting department works on the future, its major league personnel are making hay in the present. The Diamondbacks are baseball's hottest team, having reeled off a 14--2 stretch through Sunday to move into first place in the NL West. The run coincides with the May 14 insertion of rookie righty Josh Collmenter (3--1, 1.49 ERA) into the rotation and the exiles of Barry Enright (6.49 ERA) and Armando Galarraga (5.91). And the revamped bullpen—new G.M. Kevin Towers's off-season focus—has played a big part. Led by new closer J.J. Putz, Arizona's bullpen ERA is 3.33, much better than last year's 5.74, the worst in NL history. The D-Backs could stick around thanks to a very soft June schedule featuring the AL Central, the Nationals and the Pirates.
