Diamondbacks Just Reopened A Frustrating September Debate

A tightly contested series against the Phillies highlights the Diamondbacks' struggles with runners in scoring positions, as they fight to stay in the wild-card race.

The Diamondbacks kept making this one look like it might crack open, but it never did. In the end, Philadelphia walked out of Chase Field with a 2-1 win, and Arizona was left with another one-run game that hinged on one swing and a lot of missed chances.

Bryce Harper delivered the difference-maker in the third, lining an RBI double off the outfield wall to push the Phillies ahead for good. That hit was enough to hand Brandon Pfaadt his first loss since April 11 and end his streak of unbeaten starts at ten.

It was a rough outcome for Pfaadt, but not a collapse. He worked six innings on 87 pitches, allowed five hits, walked one and struck out one, and while the loss goes on the ledger, the outing was cleaner than what he managed against the Red Sox or Cubs.

The game also carried the night’s biggest off-field storyline: Ketel Marte was back in the Diamondbacks’ lineup after ten days on the Injured List with a knee issue and additional time on the Restricted List after he did not show up at Fenway Park for a game. The reception at Chase Field was mixed at first.

As Jack reported from the ballpark, “Many more booing than cheering, booers were louder, and booed again as he grounded out.” The mood around his later plate appearances seemed to soften, and Marte finished 1-for-3 with a walk.

The Phillies struck first in the second inning on a massive Bryson Stott blast that Statcast measured at 464 feet. That gave Philadelphia a 1-0 lead and set the tone for a night in which neither club really cashed in when it had a chance. Arizona and Philadelphia combined to go 1-for-15 with runners in scoring position.

Philadelphia added its second run in the third. A single and a walk opened the inning, Harper doubled with one out, and Luis Arraez put the ball in play to Ildemaro Vargas. Vargas threw home, Gabriel Moreno applied the tag, and the D-backs escaped with just the one run allowed in the frame.

Arizona answered in the bottom of the third. Moreno came through with a two-out double just fair down the left-field line, and third-base coach J.R.

House sent Geraldo Perdomo all the way home from first to make it 2-1. The D-backs had already left a runner in scoring position in the second after a Lars Nootbaar walk and a Nolan Arenado infield hit, but Tim Tawa and Vargas couldn’t bring him in.

That was the pattern the rest of the way. Arizona put two on with nobody out in the sixth when Moreno singled and Marte walked, but Nootbaar, Arenado and Tawa couldn’t move them.

The seventh brought another costly miss, as Vargas’s leadoff hit was wiped out by an ill-advised attempt to take off for second while the pitcher still had the ball. The D-backs also had two men on with one out in the eighth, and again Arenado and Tawa came up empty.

The final shot came in the ninth against Jhoan Duran, the former Diamondbacks prospect who was part of the 2018 deal that sent Arizona to Minnesota for Eduardo Escobar before later becoming the Twins’ closer and then being traded to Philadelphia in 2025. Ryan Waldschmidt and Corbin Carroll each picked up infield hits, with Carroll avoiding an 0-for-5 night, and that put the tying run in scoring position with two outs. Moreno came up with Marte waiting on deck, but he grounded out to end it.

With the Padres winning, Arizona slipped out of a wild-card spot by half a game. The series continues tomorrow night at 6:40 p.m., with Eduardo Rodriguez set to start for the Diamondbacks.

Diamondbacks Face A September Series That Could Sway Their Wild Card Fate

Philadelphias strong August has changed the tone of its September, with the Phillies settling into the No. 2 spot in the National League Wild Card picture while staring at a demanding stretch that also includes the Brewers and Braves. For Arizona, the timing matters just as much. The Diamondbacks are still in the chase, and this upcoming series gives them a chance to measure themselves against a club that has helped push the playoff race into sharper focus.

The matchup carries more than just another set of late-season games. Arizona has been trying to climb back into the conversation, and every head-to-head meeting with a contender matters when the standings are this tight. The first series between these teams in April already set a baseline, but this one arrives with far more at stake for the Diamondbacks, who need September to start cutting in their direction rather than making their path to October even steeper.

Diamondbacks Fans Have Two New Reasons To Worry At Chase Field

The Phillies kept rolling through August with a 21-7 finish, and their 2-1 win over the Diamondbacks at Chase Field was another reminder of how much trouble a hot lineup can cause in a tight game. Bryson Stott supplied the lone homer for Philadelphia, while Aaron Nola gave them a steady outing by working into the sixth inning, the kind of performance that helped them stack wins all month and put more pressure on Arizonas margin for error.

For the Diamondbacks, the game came with a little extra sting because the home crowd already had plenty to watch beyond the final score. Arizona has been sorting through injury updates on several players, and the larger concern around the club is how quickly it can settle the pieces in front of a fan base looking for answers at Chase Field.

Diamondbacks Get A Boost But One Bullpen Concern Just Got Bigger

The Diamondbacks got a timely jolt to the roster with Lourdes Gurriel Jr. and Blake Walston both coming off the injured list, a welcome development as the club keeps chasing a postseason spot. Any late-season push needs healthy bodies, and adding back an everyday outfielder along with a left-handed arm gives Arizona a little more flexibility at a point when every decision matters.

Ryan Thompsons move to the 60-day injured list only sharpens the concern on the pitching side, though, because it takes another reliever out of the mix for the rest of 2026. For a bullpen trying to hold up under the pressure of a crowded race, that kind of loss can change how the Diamondbacks manage matchups and innings the rest of the way. [Read more 🡒]
