Davey Johnson plans to sit down and talk with Bryce Harper after the youngster failed to run out a ground ball on Friday night.
Johnson hinted that Harper's health could be a factor -- he may be headed for offseason knee surgery.
"My opinion is you take nothing for granted," Johnson said. "You hit a ground ball, the guy could boot it, you run. Anytime you don't go hard, it's a losing attitude.
"With him, I'm in between knowing if he's babying his knee, because he's usually 100 percent in. But I'll talk to him."
