The Washington Nationals placed outfielder Bryce Harper on the 15-day disabled list on Saturday because of bursitis in his left knee.
The move is retroactive to May 27, as Harper has missed the team's last five games. The 20-year-old's knee has bothered him since his crash into the wall at Dodger Stadium on May 13.
In a corresponding move, the Nationals recalled right-handed pitcher Erik Davis from Triple-A for bullpen depth after ace Stephen Strasburg lasted only two innings in Friday's game, departing with a strained right oblique.
Harper, who is hitting .287 with 12 home runs and a .973 OPS in his second season, last missed time in August 2011 with a hamstring injury in the minor leagues.
