Joe Nathan slammed the door on the Royals in the ninth inning on Friday, preserving a one-run advantage and earning his 19th save of the season. The 39-year-old closer has pitched better of late, but still owns a troublesome 5.61 ERA, 1.51 WHIP and 35/14 K/BB ratio over 33 2/3 innings on the season. He isn't a good bet to magically turn his season around and improve his ratios, but should continue to be able to rack up saves at the back of the Tigers bullpen.
