Nationals right fielder Bryce Harper will move to center field, in place of Denard Span, for Saturday's game.
"What we have to be mindful of is that we don't want to push [Span] too hard, because this is a long-term thing," manager Matt Williams said to MLB.com. "We have a lot of games left. I want to make sure he is healthy for the rest of the season. Four in a row and a day off is probably the best thing to do. After today, let him go again. He'll let us know how he feels from there. He is playing well."
Reed Johnson gets his second start of the season in right.
The Nationals are -150 money line favorites at Miami.
