The Arizona Diamondbacks gutted out a 7-6 extra-innings victory over the Boston Red Sox on Wednesday, August 19, 2026, at Fenway Park, completing a two-run comeback to win in ten innings. Lars Nootbaar delivered the big blow with a home run and two RBI, Jonathan Loáisiga threw two scoreless innings to earn the win, and Jovani Morán took the loss after a shaky tenth. This was not a clean win — Brandon Pfaadt was roughed up for five earned runs — but Arizona found a way, and in a one-run game that required a comeback, finding a way is what matters.

Diamondbacks Overcome Two-Run Deficit to Win 7-6 in Extra Innings

Pfaadt was far from his best Wednesday night. The right-hander went 5.2 innings, allowed seven hits and five earned runs, and left the game with Arizona in a hole. To his credit, he punched out eight batters without issuing a single walk, which kept Arizona from completely unraveling in the middle innings. But Boston's lineup — led by Mickey Gasper's home run and three RBI on just one hit in three at-bats, plus home runs from Jarren Duran and Nick Sogard — made Pfaadt work hard for every out.

Arizona's bullpen steadied things after Pfaadt's exit. Juan Morillo tossed a clean inning, allowing one hit and striking out one. Brandyn Garcia worked two-thirds of an inning without allowing a run. Kevin Ginkel covered two-thirds of an inning with a scoreless frame. Then Loáisiga took over and shut Boston down across the final two innings, holding the Red Sox scoreless on one hit while walking no one — giving Arizona's offense the time it needed to complete the comeback.

Nootbaar, Arenado, and Fernandez Lead Arizona Offense

On the offensive side, Arizona got contributions up and down the lineup. Nootbaar was the most explosive, going 1-for-2 with a home run and two RBI. Nolan Arenado went 2-for-5 with an RBI, providing the kind of steady, professional at-bat production Arizona needed when the game was on the line. Jose Fernandez added a 2-for-4 night with an RBI, and Ryan Waldschmidt chipped in with two hits and an RBI in three at-bats. This was a collective offensive effort — not one singular hero — and Arizona needed every run.

Turning Point: Morán Falters in the Tenth, Arizona Capitalizes

Boston turned to Jovani Morán to close out the extra inning, but the left-hander couldn't hold on. Morán walked three batters, allowed a hit, and surrendered the decisive run in the tenth inning, ultimately taking the loss. Three walks in one inning is how games slip away, and that is exactly what happened at Fenway Park. Arizona's hitters stayed patient, worked counts, and made Morán pay.

Boston's Payton Tolle had given the Red Sox a reasonable starting effort — five innings, six strikeouts, three earned runs — but the bullpen couldn't finish the job. Greg Weissert allowed two earned runs in his inning of work, which kept Arizona within striking distance heading into the late innings.

What's Next for the Diamondbacks

Arizona heads into the remainder of this road series with some momentum after grinding out a ten-inning win. Pfaadt's outing will need to be addressed — five earned runs is not the performance Arizona needs from its starter — but the bullpen's ability to stabilize after a rough start, and the offense's patience in the tenth inning against Morán, are legitimate positives to carry forward. The Diamondbacks return to Chase Field after this road trip wraps up. For now, Wednesday night belongs to Arizona.
