A hot pitcher will face a team he has dominated in his career when right-hander Anibal Sanchez leads the visiting Washington Nationals against the San Francisco Giants on Tuesday night. The Nationals got a leg up in the three-game series that has playoff ramifications when Erick Fedde and three relievers combined to shut out the Giants 4-0 on Monday night. The win allowed Washington (59-53) to move into a tie with Philadelphia (59-53) for the top spot in the National League wild card standings, while at the same time pushing San Francisco (56-57) 3 1/2 games back.
