Washington at Arizona

Arizona has a losing record at home and the Diamondbacks are 16-40 against a team with a winning record. Righty Jeremy Hellickson (1-3, 5.85 ERA) hasn't been a good addition for Arizona. Hellickson lasted just 4.2 innings and allowed five runs on eight hits in the 6-5 loss to the Padres Friday. Washington has a veteran lefty on the mound in Gio Gonzalez (3-2, 3.62 ERA), with the team 4-1 his last five starts. The Diamondbacks are 5-12 against a left-handed starter. Meanwhile the Nationals are 33-14 when Gonzalez faces a team with a losing record, plus Washington is 8-3 in the last 11 meetings at Arizona. Take Washington.
