Later on Wednesday, Leylah Annie Fernandez of Laval, Que., and partner Jack Sock lost 7-5, 7-6(3) in the mixed doubles quarterfinals against Storm Sanders and John Peers.
Fernandez and Sock fired six aces and broke on two out of nine chances, compared to seven aces and three out of five breakpoints won for the Australian duo.
Fernandez, 20, was the last Canadian to be in the tournament. She was eliminated in the second round of both the women’s singles and doubles earlier in the event.
Meanwhile, Aryna Sabalenka returned to the semifinals with a 6-1, 7-6(4) win over Karolina Pliskova.
Sabalenka is the only one alive in both draws to reach the final four at Flushing Meadows last year. She lost in the semifinals to runner-up Leylah Fernandez.
The number 6 from Belarus will face Iga Swiatek or number 8 Jessica Pegula for a spot in her first Grand Slam final.
She reached her only other major semifinal at Wimbledon last year, where Pliskova defeated her before going down to Ash Barty.
Sabalenka quickly showed that this match-up would be very different, racing to a 4-0 lead against the 2016 US Open runner-up and finishing the first set in 28 minutes.
Tiafoe becomes the first American man to reach the semifinals of the US Open since 2006
Frances Tiafoe became the first American man to reach the semifinals of the US Open since 2006 by beating Andrey Rublev 7-6(3), 7-6(0), 6-4 behind the support of a rowdy partisan crowd in Arthur Ashe Stadium on Wednesday .
“Man, man, this is wild. This is crazy. I had the biggest win of my life 24 hours ago… That’s tremendous growth. It’s hard to turn the page,” said Tiafoe, who placed 22nd at Flushing Meadows.
Then, looking ahead and making sure everyone knows that this big milestone isn’t enough to satisfy him, Tiafoe said, “Let’s enjoy this. We’ve got two more, guys. We’ve got two more.”
Andy Roddick was the last American man to reach the semifinals in New York when he lost to Roger Fededer in the title match 16 years ago. Roddick was also the last man in the country to win a Grand Slam singles championship, winning the 2003 US Open.
Tiafoe’s first career Grand Slam semifinal comes Friday against No. 3 Carlos Alcaraz or No. 11 Jannik Sinner.
Tiafoe played aggressive, attacking tennis and used 18 aces along with strong volleys to oust number 9 Rublev, a Russian who fell to 0-6 in the major quarter-finals. Tiafoe won 31 of 41 points when he went to the net; Rublev ventured forward only 11 times.
