The San Francisco Giants dropped a gut-punch 4-2 decision to the New York Mets on Sunday, September 6, 2026, at Citi Field. Closer Carson Seymour couldn't hold a two-run lead in the ninth inning, surrendering four runs on three hits before recording an out, turning a solid pitching effort into a deflating loss. Bo Bichette did the most damage for New York, going 1-for-4 with a home run and three RBI. The Giants had the lead entering the final frame and couldn't close it out — a result that stings no matter when it happens.

Giants Pitching Dominates for Eight Innings, Then Collapses in the Ninth

For most of this game, the Giants pitching staff was the story — and a good one. Cesar Perdomo was outstanding in his starting role, going six full innings while allowing just three hits, one walk, and zero earned runs, striking out four. That's the kind of outing that should win ballgames. Joel Kuhnel followed with a scoreless seventh, surrendering just one hit. For eight innings, San Francisco's pitching held New York to nothing.

Then came the ninth. Seymour entered protecting a 2-0 lead and it unraveled fast. He allowed three hits and a walk, giving up all four runs that crossed the plate. The win went to Tobias Myers, the loss to Seymour. It was a brutal ending to what had been a competent team effort on the mound.

Bo Bichette and Brett Baty Power Mets Comeback

The Mets' offensive resurgence in the ninth was built around two swings. Bichette's home run drove in three runs and served as the centerpiece of the rally. Brett Baty added a solo shot of his own, going 1-for-1 with one RBI on the night. A.J. Ewing contributed two hits in three at-bats to keep New York's lineup moving, though it was the power from Bichette and Baty that truly broke the game open.

The Giants' box score offered no highlighted individual offensive performers in the data — San Francisco managed just enough to build a two-run lead through eight innings against a deep Mets pitching staff, but couldn't add insurance runs when they had the chance.

Mets Pitching Staff Shuts Down Giants Bats

New York's pitching deserves credit. Christian Scott worked 4.2 innings, striking out seven while allowing two earned runs on four hits with no walks — a strong performance that kept the Giants from pulling away early. Nate Lavender bridged the gap with a perfect 0.1 innings and a strikeout. Jonathan Pintaro then threw two scoreless innings, allowing nothing. Kodai Senga closed it out with a 1-2-3 ninth to earn the save, punching out one batter and securing the win for New York.

Combined, the Mets' pitching staff struck out 11 Giants batters. San Francisco's lineup simply couldn't generate enough offense against that kind of collective effort.

Turning Point: The Ninth Inning

There's no ambiguity about where this game was decided. San Francisco entered the ninth with a 2-0 lead and needed three outs. Seymour didn't get them cleanly. Four runs scored, the lead evaporated, and the Mets walked away with a 4-2 victory. The metadata confirms New York overcame a two-run deficit — that's the entire story of this loss in one brutal sentence.

What's Next for the Giants

  • San Francisco will look to regroup following this series loss in New York.
  • The bullpen's performance in the ninth will demand attention — Seymour's outing (4 ER, 3 H, 1 BB in 1.0 IP) was a damaging one at a critical moment.
  • Perdomo's strong start (6.0 IP, 0 ER, 4 K) provides a positive note to build on in the rotation going forward.
  • The Giants will need their offense to provide more cushion when the starting pitching performs at this level.
