The Nationals have placed outfielder Ben Revere on the 15-day DL with a right oblique strain and recalled outfielder Matt den Dekker from Syracuse to take his place on the 25-man roster.
Revere, who was acquired in January in the trade that sent Drew Storen to Toronto, was supposed to solidify the top of the order for Washington, which struggled last season after losing leadoff man Denard Span to injury. In Monday's season opener in Atlanta, Revere was the starting center fielder and leadoff hitter, but he was pulled in the fourth inning.
