The Arizona Diamondbacks handed the Houston Astros a 3-2 defeat at Minute Maid Park on Sunday, September 6, 2026, with Nolan Arenado delivering the decisive blow — a two-run home run that gave Arizona the margin it needed to hold on. Peter Lambert turned in seven solid innings but absorbed the loss, and Houston's late-game push came up one run short despite a three-hit performance from Jose Altuve and a solo home run from Yordan Alvarez.

Astros Offense Generates Chances but Cannot Solve Arizona's Bullpen

Houston put the ball in play and manufactured traffic throughout the night. Altuve went 3-for-4, providing the Astros with a consistent table-setter at the top of the order. Alvarez connected for a solo home run — his lone hit in five at-bats — to account for one of Houston's two runs. The problem was that the offense never fully broke through against Arizona starter Eduardo Rodriguez, who worked six innings, allowed just three hits, struck out six, and walked two while surrendering only one earned run. Rodriguez earned the win.

The Astros had opportunities, but converting them against a capable Arizona pitching staff proved too tall an order on this evening. Kevin Ginkel closed the game out in dominant fashion — three strikeouts in the ninth, no hits, no walks — to earn the save and seal the 3-2 final.

Peter Lambert Pitches Well but Takes the Loss

Lambert's outing deserves more than a single line in a loss column. The right-hander went seven full innings, struck out six, issued zero walks, and gave up seven hits. He allowed all three Arizona runs, but his work kept Houston in the game deep into the evening. That is the kind of outing a rotation needs, especially when the offense is working to find its footing against a quality opposing starter.

The bullpen handled the final two innings cleanly. Miguel Ullola pitched a scoreless eighth — one strikeout, one hit allowed — and Bryan Abreu matched that in the ninth before Ginkel entered to close for Arizona. Houston's relief work did not give the game away; the damage was done earlier against Lambert.

Arenado's Home Run Was the Turning Point

Arenado went 1-for-4, but that one hit was the difference in the game. His two-run home run off Lambert gave Arizona a lead it never relinquished. Corbin Carroll added two hits in four at-bats for the Diamondbacks, giving their lineup some additional punch against Lambert's otherwise efficient night.

The metadata confirms this game included a comeback element — Arizona overcame a one-run deficit at some point — which underscores how competitive the back-and-forth was at Minute Maid Park. In the end, Arenado's swing carried the most weight.

What's Next for the Astros

Houston drops this one at home and will need to respond. The pitching held up its end of the bargain on Sunday — Lambert's seven-inning, zero-walk performance and two scoreless relief innings from Ullola and Abreu gave the offense every chance. Getting two runs off Rodriguez and his bullpen was not enough, and that is the honest takeaway from this 3-2 defeat. The Astros move forward in the 2026 regular season with work to do.
