SAN FRANCISCO — Justin Verlander added another memorable chapter to his legendary pitching career Sunday, yet was hardly in the mood to celebrate.

Verlander struck out the side in the first inning against the Nationals to become the 10th pitcher in MLB history to reach 3,500 career strikeouts. Not long after, things began to unravel for the three-time Cy Young Award winner as the Giants dropped an 8-0 decision to Washington in front of 40,000 fans at Oracle Park.

Washington scored four times in the second inning and five overall on 11 hits against Verlander in the latest outing in what has been a season-long struggle for the 42-year-old.

“I was happy to get there, happy to have a moment with the fans,” said Verlander, who is 1-9 in 20 starts with the Giants and has a 4.53 ERA. “Cool milestone. I really appreciate what it’s taken to get there.”

Verlander hasn’t given the Giants much to celebrate this season, though he had been in the best stretch of the season before getting roughed up Sunday. In his three previous games, Verlander had a 0.60 ERA with 14 strikeouts in 15 innings.

He finished with six strikeouts against the Nationals, but spent most of his postgame media session focused on his season rather than the 3,500 strikeouts.

Though acknowledging frustration about his 2025 results, Verlander likened his performances to the 2022 campaign, when he went 18-4 with a 1.75 ERA with the Houston Astros en route to winning his third Cy Young.

“Stuff’s great, stuff’s fine,” Verlander said. “I’ve spent a lot of the season looking at comparables. It’s right on par, literally almost up and down the board, with [2022] when I won the Cy Young. So, I think the stuff is just fine. The results have been frustrating.”

With 3,503 career strikeouts after Sunday’s outing, Verlander trails Walter Johnson by 11 strikeouts for ninth most on the all-time list.
