Marlins third baseman Martin Prado was scratched from Friday's lineup against the Nationals, Joe Frisaro of MLB.com reports.
Prado was initially slated to serve his usual third base duties and bat third, but a late lineup change has Derek Dietrich sliding over the third with Marcell Ozuna now in the lineup instead. It's unclear exactly why the change was made, but further news on the situation should become available.
