WASHINGTON (AP) – Bryce Harper hit a slump-busting home run, Danny Espinosa also went deep and the Washington Nationals got seven strong innings from right-hander Joe Ross in a 2-1 victory over the St. Louis Cardinals on Thursday night.

Washington trailed 1-0 in the sixth inning before Harper ended a 4-for-33 skid with a no-doubt-about-it shot into the upper deck, far beyond the wall in right field. It was his 12th homer of the season, the first since May 13.

The light-hitting Espinosa snapped the tie in the seventh with a drive to right. Batting eighth, Espinosa came in with a .199 batting average and three home runs.

Both homers came off Mike Leake (3-4), who won his previous three starts while allowing only two runs over 21 innings.

Ross (4-4) gave up one run and six hits over seven innings. He had lost four straight decisions since beating the Cardinals in St. Louis on April 30.
