I know this one isn't pretty, but +240 isn't going to be, but a win on a play like this is worth more than two Ws.
Merrill Kelly is 0-4 against the Dodgers this season, and 0-8 against them with a 5.81 ERA in his career. The Dodgers are also 11-1 against Arizona in those games. As bad as that track record is, I believe Kelly and the Dbacks are due for this win. Kelly is having an excellent season, and is 8-1 with a 2.95 ERA on the road. This is also a meaningless game for the Dodgers coming off of Sunday Night Baseball and a sweep of the Giants. In a divisional game between two aces, Arizona has nothing to lose, and the Dodgers don't have much to game. This is far from a lock, but this is a risk worth taking for me.
