It was the most improbable sweep of the season so far. The Pirates are coming off a three-game sweep of the Dodgers.

Now, following an off day yesterday, the Pirates host Arizona. The Diamondbacks are a respectable 25-27, pushing to get to .500. Pittsburgh is 22-27 and 0-9 the past nine times when playing following an off day.

Arizona is going with Merrill Kelly. He has a 3.67 ERA and 1.35 WHIP. The Pirates are starting JT Brubaker, who is 0-4 with a 4.15 ERA and 1.38 WHIP. Advantage Diamondbacks.

The Diamondbacks have defeated the Pirates 11 of the past 13 times in Pittsburgh.

Arizona is the better team. The Pirates are in their first letdown series of the season. So I'll take the Diamondbacks.
