Arizona at San Diego

Arizona has a winning road record, on a 16-7 run away from home, and has its ace going. Arizona is 9-3 against losing teams, plus 12-5 away versus a right-handed starter. Diamondbacks starter Zack Greinke (11-5, 3.05 ERA) is 6-0 with a 1.57 ERA over his last seven starts and has won eight of his last nine decisions. The Diamondbacks are 1.5 games behind the first-place Dodgers in the NL West and 20-6 when Greinke faces a losing team. He faces a San Diego offense that is #28 in baseball in runs scored, #29 in on-base percentage, and last in slugging. They have a lot of problems, including starter Luis Perdomo (6.99 ERA), who has allowed 71 base runners in 31 innings. Batters are hitting .327 off him. The Padres are on an 8-25 run, as well as 18-38 following an off day, so back the surging visitors and play Arizona.
