Bryce Harper, who had three hits in Monday’s 9-2 win over the Miami Marlins, exited in the seventh inning with a tight left quad that isn’t expected to keep him out of the lineup on Tuesday. Manager Matt Williams took the outfielder out of the game after he tripped running to third base on a groundout. Williams said the stumble aggravated the quad, but Harper said he simply tripped over his feet.

“He’s fine,” Williams said. “I don’t think there’s any big issue. But we got him out just to make sure he could get some work done [Monday night]. See how he is [Tuesday], but I expect him in the lineup. I don’t think there’s a big issue.”

Either way, Harper ran slightly funny to third base and was replaced by rookie Steven Souza Jr. in center field in the bottom half of the inning. Harper said his quad has been tight since Friday in Atlanta and referred to it as “nothing too serious.” It hasn’t held him out of the lineup.

“Getting treatment every day and it feels fine,” he said. “Ready to go [Tuesday].”

After a slow start, Harper is hitting .348 (16 for 48) with five extra-base hits, five walks and five RBI.

>>> Denard Span, who suffered a concussion on Friday, was evaluated by a doctor after taking batting and running on Monday and felt fine, Williams said. He will do physical activity on Tuesday and be monitored again. He could head back to Washington on Wednesday ahead of the Nationals if he feels fine after Tuesday’s round of activity.
