WASHINGTON -- The San Francisco Giants completed a doubleheader sweep of the Washington Nationals with a rain-shortened 4-1 victory. The game, which followed Randy Johnson's 300th career victory in the opener, was called with two outs in the top of the sixth after a delay of 67 minutes.
Matt Cain (7-1) won his fifth consecutive decision. San Francisco broke a 1-1 tie in the fifth with a five-hit rally against Ross Detwiler (0-2), including a run-scoring double by Pablo Sandoval and RBI singles by Aaron Rowand and Rich Aurilia.
"To get the 300th win for R.J. is huge," Cain said. "It was my intention to keep the momentum going for us."
- Johnson is the fourth pitcher to win his 300th with the Giants, joining Christy Mathewson in 1912 and Tim Keefe and Mickey Welch, both in 1890.
- Washington OF Josh Willingham remained sidelined with a stomach virus.
- The Nationals have lost eight of nine and 20 of 24.
