WASHINGTON -- The Nationals lost right-hander Juan Jaime, who was claimed off waivers by the D-backs on Friday afternoon, according to two baseball sources.
Jaime was taken off Washington's 40-man roster recently and was placed on waivers before Arizona acquired his services.
Jaime missed all of 2010 while recovering from Tommy John surgery. Jaime joined Washington's system in '06 as a free agent and has yet to pitch in a Major League game.
In four seasons in the Nationals organization, Jaime has pitched in 42 games, going 10-3 with a 2.42 ERA. He struck out 146 batters in 111 2/3 innings.
Before he injured his elbow, Jaime's fastball was clocked as high as 98 mph. One source believed that Jaime had the best arm in the organization outside of right-hander Stephen Strasburg.
