Arizona is 6-2 in their last 8 games and 12-4 in their last 16 games against a team with a winning record. The over is 9-4 in Arizona’s last 13 road games. Pittsburgh is 2-6 in their last 8 home games and 4-13 in their last 17 games. The under is 16-6-1 in Pittsburgh’s last 23 game three’s of a series. Arizona is 23-8 in these two teams last 31 head to head meetings.


Pittsburgh has started to play better in recent games after they really struggled over the last two weeks. Pittsburgh is starting Roansy Contreras, who has allowed 11 earned runs over his last 17.1 innings pitched. Arizona is starting Merrill Kelly, who has allowed one earned in three of his last four starts. Kelly has been very good for the Diamondbacks this year and I like them to get the win here.
