Washington at San Francisco

This is a long road trip for Washington, 3,000 miles from home and on the third game of a nine-game trip. Washington is 5-6 since the break and part of the reason for its mediocrity is that star Bryce Harper is 0-for-17 over his last five games and batting .177 in July, dropping his season average to .237. Starter Tanner Roark gave up five earned runs on four hits over five innings in Friday's 5-3 loss to the Padres. The Nationals are just 2-9 against the National League West. San Francisco has a strong all-around team and is home, where the Giants are on a 19-7 run. Ace Johnny Cueto (13-2, 2.53 ERA) is having a monster season and the Giants are 14-2 in his last 16 starts. The Nationals have lost five in a row in this park and this shapes up as a one-sided rout for the home team. Take San Francisco on the runline.
