LONDON — All these years later, Wimbledon still brings out the best in Venus Williams.

With her latest display of gutsy serving and big hitting, Williams beat Johanna Konta 6-4, 6-2 on Thursday to reach her ninth title match at the All England Club and first since 2009.

At 37, Williams is the oldest Wimbledon finalist since Martina Navratilova was the 1994 runner-up at that age.

Williams also stopped Konta’s bid to become the first woman from Britain in 40 years to win the country’s Grand Slam tournament.

“I couldn’t have asked for more, but I’ll ask for a little more. One more win would be amazing,” Williams said. “It won’t be a given, but I’m going to give it my all.”

She will be seeking her sixth Wimbledon championship and eighth Grand Slam singles trophy overall. Her most recent came in 2008, when she defeated her younger sister, Serena, for the title at the All England Club. A year later, she lost the final to Serena.

In the time since, Williams revealed that she was diagnosed with Sjogren’s syndrome, which can sap energy and cause joint pain. As time went on, there were questions about whether she might retire, especially after a half-dozen first-round losses at major tournaments. But she kept on going, and lately has returned to winning.

Her resurgence began in earnest at Wimbledon a year ago, when she made it to the semifinals. Then, at the Australian Open in January, Williams reached the final, where she lost to — yes, you guessed it — her sister. Serena is off the tour for the rest of this year because she is pregnant.

“I missed her so much before this match. And I was like, ‘I just wish she was here.’ And I was like, ‘I wish she could do this for me,’” Williams said with a laugh. “And I was like, ‘No, this time you have to do it for yourself.’ So here we are.”

On Saturday, the 10th-seeded American will participate in her second Grand Slam final of the season, and 16th of her career, this time against 14th-seeded Garbine Muguruza of Spain.

“She knows how to play, especially Wimbledon finals,” Muguruza, the 2015 Wimbledon runner-up and 2016 French Open champion, said about Williams. “It’s going to be, like, a historic final again.”

Muguruza overwhelmed 87th-ranked Magdalena Rybarikova of Slovakia 6-1, 6-1 in the earlier semifinal.

In the semifinals, it was Konta who had the first chance to nose ahead, a point from serving from the opening set when it was 4-all and Williams was serving down 15-40.

Williams erased the first break point with a backhand winner down the line, and the second with a 106 mph (171 kph) second serve that went right at Konta’s body. It was a risky strategy, going for so much pace on a second serve, but it worked. That opened a run in which Williams won 12 of 13 points.
