SAN FRANCISCO (AP) -- Outfielder Bryce Harper is back in the Washington Nationals' lineup after missing two games because of a bruised left knee.

Harper was batting third and playing right field Monday night at San Francisco. Last season's NL Rookie of the Year was hurt last week when he ran into a wall at Dodger Stadium.

Harper did some running and work on the field before the game against the Giants. Manager Davey Johnson said Harper told him he was fine to play.

The 20-year-old Harper ran into the wall last Monday against the Dodgers and needed 11 stitches in his chin.
