The St. Louis Cardinals held off the San Francisco Giants 2-1 on Monday, September 14, 2026, at Busch Stadium, with Quinn Mathews delivering a sharp 6.2-inning performance and Leo Bernal providing the offensive spark in a tight, well-played nine-inning ballgame. With the margin never wider than one run, this was the kind of grind-it-out victory that requires contributions across the entire roster — and on this night, the Cardinals got them.

Quinn Mathews Controls the Game for St. Louis

Mathews was the story on the mound. The lefty worked 6.2 innings, allowing just one earned run on four hits while walking two and striking out eight. That is a starter doing exactly what a staff needs in a one-run ballgame — keeping the bullpen fresh and keeping San Francisco's lineup uncomfortable all night. He earned the win, and it was deserved.

When Mathews exited with two outs in the seventh, Justin Bruihl came on and got the inning-ending out without allowing a baserunner. Ryne Stanek then handled the eighth, striking out two in a clean inning despite allowing a hit and a walk. Riley O'Brien closed it out in the ninth, punching out two batters and earning the save to nail down the Cardinals' 2-1 final.

Bernal and Burleson Provide the Offense

St. Louis generated just enough offense against Giants starter Landen Roupp and a parade of San Francisco relievers. Leo Bernal was the Cardinals' best bat on the night, going 3-for-4 with an RBI. Thomas Saggese added a 2-for-4 effort at the plate, and Alec Burleson chipped in with two hits and an RBI in three at-bats. The Cardinals scratched out both of their runs against Roupp, who lasted only 4.1 innings, allowing five hits, three walks, and two earned runs.

San Francisco cycled through four relievers after Roupp's early exit — Reiver Sanmartin, Joel Kuhnel, Trent Harris, and Carson Seymour — and the Cardinals were unable to push across a third run, but two proved to be enough.

Turning Point: The Fifth-Inning Offensive Push

The Cardinals did their damage against Roupp before the Giants bullpen locked things down. With Bernal driving in a run and Burleson adding another, St. Louis built the 2-1 cushion that Mathews and the bullpen then protected for the remainder of the game. San Francisco got one back against Mathews but never found the equalizer, in large part because O'Brien was lights-out in the ninth when it mattered most.
