Usually when we think about Bryce Harper, we think about what he produces. The homers that fly when that big, violent swing of his connects. That happened again Monday, as his Washington Nationals stayed alive in the NLDS with a 4-1 win against the San Francisco Giants . But it was Harper's other instrument, his glove, which made the bigger impact in the game. Twice, he took away runs from the Giants with his play in left field, and that proved more important than what he produced with his bat. Harper made a nice catch at the wall in the second inning when the Giants had two runners on. Brandon Crawford's long drive looked it might bang off the wall and bring around two runs, but Harper jumped and made the catch. It was him banging off the wall. "If he doesn't run that down," said Giants second baseman Joe Panik, "that changes the whole mindset of the game."
