Phillies vs. Diamondbacks Prediction: Can Nola Solve Pfaadt’s Hot Streak?
Phillies visit Chase Field on a four-game win streak, but Brandon Pfaadt's dominant summer run makes Arizona the value play at plus money.
Aaron Nola and his 5.03 ERA have to walk into Chase Field and beat a pitcher who hasn’t lost since June.
Quick take:
- Pick: Diamondbacks +101
- Why: Brandon Pfaadt’s 3.51 ERA and 1.14 WHIP against Nola’s struggles flip the value onto Arizona at plus money
- The number to watch: Pfaadt is 7-1 this season and hasn’t allowed an earned run in a start between July 23 and August 14
The Phillies roll into the desert with the look of a team that’s figured something out. Philadelphia is 77-60, sitting second in the NL East five games back of Atlanta, and they’ve won eight of their last ten while riding a four-game win streak into Monday night. Arizona, meanwhile, is 73-65 and stuck nine and a half games behind the Dodgers in the NL West, having dropped their last game and gone just 6-4 over their own last ten.
Records aside, this is a pitching matchup that cuts against the Phillies’ momentum. Nola gets the ball for Philadelphia carrying a rough 5-10 record and that 5.03 ERA, a far cry from the ace-level numbers Phillies fans are used to seeing from him. Pfaadt, on the other hand, has been one of the best stories in baseball since his June 30 recall from Triple-A Reno — he’s 7-1 with a 3.51 ERA and a tidy 1.14 WHIP, and at one stretch this summer he didn’t allow an earned run for three straight weeks.
Why the Market Is Splitting Hairs on This One
The line has bounced around slightly depending on the book, but it’s settled close to even money — Phillies around -121 to -125, Diamondbacks around +101 to +105, with the total sitting at 8.5 runs. That’s a tight number for a team that’s won four straight and sits comfortably ahead of Arizona in the standings, and it’s a clear signal the market respects what Pfaadt has done on the mound far more than it respects Nola’s season-long profile. Some shops even have Arizona catching a modest push at the plate late, with the total holding steady rather than climbing, which tells you sharp money isn’t buying a Phillies blowout in this park.
Pfaadt’s Turnaround Meets a Lineup That’s Cooling at the Wrong Time
Kyle Schwarber remains the engine of this Phillies offense, sitting on 40 home runs and 82 RBI with a .530 slugging percentage that leads the club, and Bryce Harper isn’t far behind with 27 homers and a .386 on-base percentage that makes him a nightmare to pitch around. Cristopher Sánchez has been the team’s most reliable arm all year at a 2.52 ERA, but he’s not on the mound Monday — Nola is, and his 1.40 WHIP means Arizona’s lineup should see plenty of traffic even against a Phillies bullpen that’s been steady behind him.
Arizona counters with a lineup anchored by Ketel Marte, who’s driven in 67 runs with 117 hits this season, and Corbin Carroll, who’s added 19 home runs even amid an uneven .244 batting average. Eduardo Rodríguez has quietly put together a 2.50 ERA of his own for the Diamondbacks, but the name that matters most Monday is Pfaadt, who has completely rewritten his season since returning from Reno.

- Brewers vs. Cubs Prediction: Milwaukee’s Best Record Meets Wrigley Field Resistance
Pfaadt has a 1.14 WHIP over 105 innings this year, nearly a quarter-run better than Nola’s 1.40 mark across a similar workload.
That WHIP gap is the whole ballgame here. Nola has been prone to extended innings and traffic on the bases all season, and against a Diamondbacks lineup that still has thump in the middle of the order, that’s a dangerous combination. Chase Field’s hitter-friendly dimensions only add to the risk for a Phillies staff that’s already shown cracks against quality bats this month, including a pair of losses in Seattle where the offense went cold at the same time the pitching did.
Prediction and Best Bet
Philadelphia’s win streak and superior record make them the popular pick, but this is a spot where the pitching matchup should decide things. Pfaadt’s command and the Diamondbacks’ need to protect home field against a divisional contender-caliber opponent both point toward a tighter, lower-scoring game than the total suggests — one where Arizona’s bullpen and Pfaadt’s steadiness carry the day.

The pick:
- Prediction: Diamondbacks 5, Phillies 3
- Best Bet: Diamondbacks on the moneyline
Pfaadt’s recent form is too strong to fade at plus money against a Phillies starter still searching for consistency.
