How nasty is Darvish's slider? Ask Arizona right fielder Gerardo Parra, who was corkscrewed while swinging at a third strike during his third-inning at-bat. Parra, who is hitting .308 this season, was fooled so badly, he tweaked his left leg and walked from the batter's box with a slight limp. He left the game with a left calf cramp.
