Nats' Beimel on DL with hip injury
Tuesday's moves come just two days after the right-handed Rivera was sent down to the minors as part of a major overhaul of Washington's struggling bullpen.
Beimel strained his left hip flexor while making a defensive play in the eighth inning of Washington's 3-2 victory over Atlanta. The left-hander has a 1.23 ERA in eight relief appearances this season.
Rivera is 0-3 with a 12.27 ERA in six outings in 2009, including a blown save Sunday in a loss to Florida.
