Davey just checking on Harper during exchange

WASHINGTON -- Bryce Harper hustles on every ball he puts in play, whether it's a double down the line or a routine ground ball. So when he merely jogged to first base after flying out to left field in the seventh inning, manager Davey Johnson was worried.

"I was concerned about his leg bothering him because he didn't round the base," Johnson said, referring to the left knee that caused Harper to miss 31 games earlier this season. "That was all that was about."

Harper and Johnson were seen arguing in the dugout.

"He was checking on my leg and seeing how I felt," Harper said, adding that the exchange wasn't as animated as it looked. "I just told him that I felt fine and I didn't want him to take me out of the game. I wanted to stay in the game."

Added Johnson: "It wasn't bad enough to come out of the game."
