Washington at Arizona

This is a long road trip for the Nationals, a team with a losing road record. Stephen Strasburg has lost two of his last three starts, and departed after three innings in his last outing against Miami due to upper back and shoulder issues. The Nationals are 1-8 on the road against a team with a losing home record. Arizona is home and has a terrific young arm going in Rubby De La Rosa (3-2). De La Rosa is coming off a strong outing in which he blanked San Diego on three hits over seven innings. He has yet to lose at home this season, going 2-0 with a 3.26 ERA in three starts. De La Rosa, who never has faced Washington, has struck out 38 against 10 walks in 37 innings. Play Arizona.
