Joe Nathan needed just 13 pitches to slam the door on the Astros in the ninth inning on Monday, preserving a 2-0 victory for the Tigers. Nathan secured his sixth save of the season for his efforts. He did allow a leadoff walk to Dexter Fowler, but he was gunned down attempting to steal second base. The veteran right-hander now sports a 4.63 ERA, 1.37 WHIP and 12/6 K/BB ratio through his first 11 2/3 frames.
