PHOENIX -- David Hernandez showed up at work Wednesday wearing a t-shirt with a big, backward K on the front. It caught at least one clubhouse observer looking.
But why not? If you have it, flaunt it, and Hernandez and the rest of the Diamondbacks relievers have a lot of reasons to feel good about themselves these days.
The D-backs won the NL West with a solid, sometimes spectacular bullpen last year, and it appears as if they can count on that same kind of shutdown effectiveness as they attempt to make up ground in the 2012 stretch drive. It took a while, but the bullpen is back. You can look it up.
Hernandez has Kd frontward and backward opponents at a rate that is among the highest in the major leagues. With his 95 mph fastball and 81-84 mph slurvey breaking ball, he is averaging 13.33 strikeouts per nine innings. So for every inning in which he strikes out one, the next inning he strikes out two.
