Arizona is 4-0 in their last 4 Friday games and 5-2 in their last 7 game one’s of a series. The over is 8-3 in Arizona’s last 11 road games. Pittsburgh is 9-4 in their last 13 games following a win and 19-45 in their last 64 Friday games. The under is 4-0-1 in Pittsburgh’s last 5 game one’s of a series.

Both of these teams have had positive starts to the season, but Pittsburgh has struggled over the last two weeks. Arizona has been very good offensively and they have scored five or more runs in four of their last five games. Zac Gallen is starting for Arizona and he has allowed a total of six earned runs in his last 33 innings of work. The Pirates will start Johan Oviedo, who has allowed 18 earned runs over his last 18 innings. I like Arizona to win this game by at least two runs.
