Arizona Diamondbacks vs Pittsburgh Pirates Recent Form & Pitching Notes
Arizona Diamondbacks (55-51): Arizona’s last game was a 10-7 loss at Washington on July 26. Starter K. Drake went 4.0 IP and allowed 4 ER (2 HR), and the bullpen got tagged for 6 runs behind him with J. Loaisiga (1.0 IP, 2 ER) taking the loss and Brandyn Garcia (1.0 IP, 3 R, 2 ER) wearing the big inning. Offensively they still put up 7: Geraldo Perdomo and Ketel Marte both homered, and Gabriel Moreno had 2 hits and 2 RBIs.
Pittsburgh Pirates (54-52): Pittsburgh’s last game was an 8-7 win vs the Cubs on July 26. Braxton Ashcraft worked 6.0 IP allowing 4 ER, and the bullpen used just two arms to get home: Carmen Mlodzinski covered 2.0 IP and Mike Montgomery closed 1.0 IP for the save despite allowing 2 ER. The offense did the damage early with Ryan O’Hearn’s grand slam (4 RBIs) plus homers from Esmerlyn Valdez and Joey Ross.

Arizona Diamondbacks vs Pittsburgh Pirates Breakdown
This is basically a coin-flip price on paper, but the Pirates’ offense isn’t priced like a top-tier unit: they’re sitting at a .760 team OPS and 5.22 runs/game, while Arizona’s at .709 OPS and 4.52 runs/game. That’s a real gap for a short home number.
Pitching isn’t giving Arizona enough separation to justify taking the road side. Kelly’s been a contact/traffic profile all year (1.48 WHIP), and Keller’s recent form has been shaky too, but Pittsburgh’s lineup is the one that can actually punish mistakes in this matchup. Add in Arizona’s bullpen just giving up 6 runs yesterday, and Pittsburgh’s path to winning is cleaner.
Arizona Diamondbacks vs Pittsburgh Pirates Best Bet
Pittsburgh Pirates Moneyline -116 (3 out of 5 units)
Pirates’ bats are carrying more of the matchup edge than the market is charging for, and Arizona’s pen is coming off a rough, run-heavy day. In a game priced near even, I’ll side with the better offense at home.
