Bryce Harper hit his first home run since May 13th off the facade of the upper deck in right and Danny Espinosa visited the second deck out there with a solo blast of his own for the only two runs the Washington Nationals needed to beat the St. Louis Cardinals tonight, 2-1. Joe Ross allowed just one run in seven strong innings to beat Mike Leake and the Cards in the series opener in D.C. as the Nationals improved to 29-19 on the year.
