The Washington Nationals and San Francisco Giants will take identical 59-42 records onto the field for the first of seven games they will play coast to coast over the next 11 days. The Nationals, who lead the NL East by four games over the Miami Marlins, rode ace Stephen Strasburg's strong seven-inning outing to a 4-1 win over the Cleveland Indians on Wednesday before boarding a flight to San Francisco. The Giants, meanwhile, retained a 2 1/2-game lead in the NL West despite a 2-1 loss to the Cincinnati Reds, a game in which ace Madison Bumgarner lost despite allowing only two runs (one earned) in eight innings.
