MIAMI GARDENS, Fla. — Ashleigh Barty needed all day to get her spot in the Miami Open women's final. Denis Shapovalov needed more than two hours to earn his berth into the semifinals.
Roger Federer, meanwhile, made winning seem relatively easy.
Federer is back in the Miami semifinals, the No. 4 seed winning the first eight games of his match and eventually ousting sixth-seeded Kevin Anderson 6-0, 6-4 on Thursday night. He won a marathon ninth game of the final set to break Anderson for a 5-4 lead, then served it out at love.
''I got a bit lucky there at the end,'' Federer said. ''But it was a great fight by Kevin and of course I enjoyed the match.''
Federer is 37 years old. That's the combined age of the two Canadian teens in the men's semifinals—Denis Shapovalov, 19, will face Federer on Friday night, and the 18-year-old Felix Auger-Aliassime will meet defending Miami champion John Isner of the U.S. earlier Friday.
''It's great for the game because they will carry the sport when we're long gone and we'll be sitting on the couch watching those guys slug it out,'' Federer said about the young Canadians. ''It'll be a joy to watch because not only are they great, great players but they're good people, too.''
Anderson hadn't lost a set 6-0 since October 2016—353 sets ago. He rallied from a break down to get back on serve in the second, before Federer took control at the end.
''They just don't happen often enough,'' Federer said of that 6-0 first set. ''I think I played a really solid, nice first set with very few mistakes.''
Barty walked away from tennis about five years ago, saying she was basically burned out at 17. She returned three years ago.
And now at 22, she's better than ever.
The 12th-seeded Barty endured enduring three rain delays on Thursday before ousting 21st-seeded Anett Kontaveit 6-3, 6-3 in the first women's semifinal.
Next up in the biggest final of her singles career: Either second-seeded Simona Halep or fifth-seeded Karolina Pliskova, who were scheduled to play late Thursday night.
''Obviously, I've been doing the right things throughout the week to put be able to put myself in a position to play for a title,'' Barty said. ''You have to go out there and embrace it.''
That was also her approach to a very long—and very wet—day at Hard Rock Stadium.
Barty, who will rise to a career-best No. 9 in the world ranking next week, was to take the court for the semifinal against Kontaveit at 1 p.m. They didn't begin play until 2:08, and the delays were just getting started.
They got three games—six minutes of tennis—in before the first in-match delay stopped things for more than two hours. They got another game in before more rain arrived, prompting another two-hour delay.
At 7:32 p.m., finally, it ended. Kontaveit fended off one match point with a forehand drop shot, but was ousted by an ace on the following point. Barty was down 3-1 in the second, but won the final five games.
''Very long day,'' said Barty, who passed the time in the locker room by drinking coffee and watching golf. ''But for me, it's an opportunity to come out and play another match. We can't control the weather.''
Shapovalov reached the semifinals by beating 28th-seeded Frances Tiafoe 6-7 (5), 6-4, 6-2—the third time in four matches at this tournament that he rallied from a set down before prevailing. And the success for Auger-Aliassime and Shapovalov in Miami follows the story of 18-year-old Canadian Bianca Andreescu winning the title at Indian Wells earlier this month.
O, Canada, indeed.
''Pretty crazy. Everyone is super excited back home,'' said Auger-Aliassime, who wasn't in the top 100 of the world rankings two months ago and now will climb to No. 33 next week—if not higher. ''It's great to hear all these good comments from them. It puts a lot of belief in tennis in Canada. I think all the Canadian players from the young kids to Denis and Bianca and I, there is a lot of belief right now, so it's great to see.''
Barty has already beaten both Halep and Pliskova in her career—but given the seeds and the respective rankings, she won't be the favorite come Saturday in the final.
And she's fine with that.
''I can go in there and play with freedom and try to play my best tennis,'' Barty said.
