Last summer, was ranked outside the top 200. This year, she entered the U.S. Open with a 38-4 record for the season, ranked No. 15.

After Andreescu defeated Belinda Bencic in the semifinals on Thursday night, Pam Shriver of ESPN told her in a postmatch interview that a year ago, “I don’t think I’d heard of you.”

It’s difficult for Andreescu to . “A year ago, I was in the qualifying round. I remember I was suffering from a back injury, and now what I’ve accomplished this year, I’m honestly speechless,” she said. “I need someone to pinch me right now. Is this real life? Is this real life?”

The 19-year-old Canadian’s rise has been swift. After a stunning victory at Indian Wells in March, Andreescu became the first Canadian in 50 years to win a final, though an abbreviated one, after Serena Williams retired in the first set because of back spasms.

If Andreescu loses the final, she will be ranked No. 9; she will be No. 5 if she wins.

This is Williams’s fourth Grand Slam final since she returned to tennis in February 2018 after the birth of her daughter.

Every time, she has had a chance to tie Margaret Court’s record for most Grand Slam singles titles: 24. Every time, Williams has lost. (In fact, she has not won any tournament since the 2017 Australian Open.)

Williams’s recent Grand Slam finals:

That is not the only record in the mix on Saturday. With a win, Williams would have a record seven singles titles at the U.S. Open, breaking her tie with Chris Evert. It would also break her tie with Evert for most singles victories at the tournament. She would have 102 to Evert’s 101.

Williams will turn 38 this month. Andreescu turned 19 in June and had not yet been born when Williams won her first Grand Slam title, at the U.S. Open in 1999.

This will be the biggest age gap in a women’s Grand Slam singles final in the Open era, which began in 1968. The gap is more than a year wider than the 17 years, 45 days that separated Martina Navratilova from the teenage phenom Monica Seles in the , won by Seles. Just a year ago, there was a 16-year gap when Williams lost to 20-year-old Naomi Osaka in an Open final.

Williams is the oldest women’s Grand Slam singles finalist in the Open era. Andreescu is playing only her fourth major tournament and is playing her first Grand Slam final.

Williams and Andreescu have one previous meeting. It lasted 19 minutes.

On Aug. 11, after a great deal of buildup, of the Rogers Cup in Toronto.

Williams fell behind by 3-1 and then retired from the match because of a back injury that she had developed in her semifinal match the day before.

“Just my whole back just completely spasmed, and to a point where I couldn’t sleep and I couldn’t really move,” she said. “And so I was just trying to figure out, how do you play a match where you have no rotation?”

Andreescu, who grew up in the Toronto suburbs, was the first Canadian woman in 50 years to win the event.

The also happens to be a rematch of a Rogers Cup final.

Bethanie Mattek-Sands celebrated her second straight United States Open mixed doubles title with Jamie Murray in the manner she knew best — by snapping a grinning selfie before the trophy was even presented.

Mattek-Sands, 34, and Murray, 33, who needed a wild card for entry because Mattek-Sands missed six months this year with her second knee surgery in 18 months, won the title with a 6-2, 6-3 upset of top-seeded Chan Hao-Ching and Michael Venus in just 59 minutes. They became the first mixed doubles team to defend their title since Anne Smith and Kevin Curren won in 1981 and ’82.

Murray, who also won the U.S. Open title with Martina Hingis in 2017, became the first man to win mixed doubles at this tournament three times in a row since Neale Fraser won with Margaret Osborne DuPont from 1958 to 1960. Margaret Court Smith won five consecutive years with four different partners from 1961 to 1965.

Mattek-Sands now owns four major mixed doubles titles and five major women’s doubles, all with Lucie Safarova. She also won Olympic gold in mixed doubles with Jack Sock at the 2016 Rio Olympics.

Juan Sebastián Cabal and Robert Farah of Colombia won the men’s doubles on Friday for their second Grand Slam title this year, after a victory at Wimbledon.

Victoria Azarenka and Ashleigh Barty will play Elise Mertens and Aryna Sabalenka for the women’s doubles title on Sunday.
