The Washington Nationals placed shortstop Ian Desmond on the 15-day disabled list Monday with a left oblique strain.
The move is retroactive to July 21.
It's the same injury that has been nagging him since before the All-Star break.
Desmond is batting .286 in 89 games this season. He leads the team with a career-high 17 home runs and ranks second with 53 RBI.
To fill the roster spot, the Nationals recalled outfielder Corey Brown from Triple-A Syracuse.
