Serena Williams came up with a comeback to reach the semifinals at Wimbledon, then walked off Centre Court with her right index finger aloft.

Yes, no matter what the rankings or seedings say, she still looks as if she’s capable of playing like someone who’s No. 1.

Williams moved closer to her eighth title at the All England Club and 24th Grand Slam trophy overall — but first since missing more than a year while having a baby — by beating Camilia Georgi of Italy 3-6, 6-3, 6-4 in the quarterfinals Tuesday.

“This is only my fourth tournament back, so I don’t feel pressure. I don’t feel I have to win this; I don’t feel I have to lose this,” Williams said. “I’m just here just to be here and to prove that I’m back. And I feel like I’m back. I still have a long way to go to be where I was.”

Williams was seeded 25th by the All England Club, a nod to all of her past success at the grass-court major, including titles the last two times she entered it, in 2015 and 2016. She missed Wimbledon a year ago because she was pregnant, and she went about 16 months between Grand Slam tournaments, so her ranking is just outside the top 180.

That is going to change now.

Next up for the 36-year-old American is a match against No. 13 seed Julian Georges of Germany, a 3-6, 7-5, 6-1 winner against No. 20 Kiki Betrens  of the Netherlands.

The 52nd-ranked Giorgi, who had never taken a set off Williams in three previous meetings, overpowered the American to take the first set, hitting more winners and aces.

Williams, however, lifted her intensity in the second set, avoiding any break points as she secured one break of her own.

Williams hit six of her seven aces in the final set, including one clocked at 122 mph, and won 44 of the last 54 points she served.

She now has a 39-35 record when losing the first set at a major.
