Scott Olsen pitched into the ninth inning, newly acquired Nyjer Morgan had three hits and the Washington Nationals beat the Atlanta Braves 5-3 on Sunday for their second straight victory.

Olsen (2-4) allowed three runs and eight hits over 8 2-3 innings, prevailing for the first time since returning June 28 from the 15-day disabled list after a bout with left shoulder tendinitis. He walked five and struck out five.

Olsen helped his own cause with his first two hits of the season, including an RBI single.

Derek Lowe (7-7), who signed a four-year, $60 million free-agent contract with the Braves in the offseason, lost for the fourth time in his past five starts.
