San Francisco at Arizona

Arizona is outstanding on offense, fifth in baseball in runs scored, and sixth in on-base percentage. All-Star Paul Goldschmidt has an NL-best .340 batting average and his 70 RBI are tied for first. The Diamondbacks are 7-1 as a home favorite and have lefty Robbie Ray (2.16 ERA) on the hill, off a 4-2 win over Texas, allowing no earned runs, and four hits in seven plus innings. San Francisco has taken a step back from a year ago, as they are a .500 road team, including an 0-7 run on the road. The Diamondbacks are 4-1 at home against a right-handed starter and face righty Matt Cain (4.09 ERA). The Giants are 9-23 when Cain starts, including 4-17 when Cain faces a team with a losing record. San Francisco is 0-4 in the last four meetings with Arizona, so grab home field and play on Arizona.
