“I think that in the third set, we obviously had a really long game at 1-all, and that was where all the momentum swung,” Keys said. “For me to get broken easily right after, I think I lost all the momentum that I had in the second set. It feels like it went really fast.”
In other men’s matches, No. 23 Pablo Carreno Busta left the court yelling at the chair umpire after a disagreement in the concluding tiebreaker of his 6-7 (8), 4-6, 7-6 (4), 6-4, 7-6 (10-8) loss to No. 8-seeded Kei Nishikori in a 5-hour, 5-minute marathon that was the longest match of the tournament.
It was the second time in four rounds Nishikori has had to come back after losing the first two sets.
Nishikori was trailing by 8-5 in the fifth-set tiebreaker when a Carreno Busta shot clipped the net, and Nishikori reset to hit a backhand down the line after the ball landed near the doubles alley.
A line judge called it out as Nishikori hit the ball down the line, and Carreno Busta was nowhere close to playing it. He challenged the decision, and Hawk-Eye showed the ball hitting the line, but the point remained with Nishikori instead of being replayed.
After arguing with umpire Thomas Sweeney, Carreno Busta lost the next three points and Nishikori sealed the match with an ace. After shaking hands with Nishikori, Carreno Busta threw his bag into the court before collecting it and yelling at the chair umpire as he left the arena.
Nishikori’s quarterfinal foe will be No. 1-seeded and six-time champion Novak Djokovic, who overcame a couple of tumbles to the court and a series of energy-sapping baseline exchanges — one point lasted 42 strokes — to beat No. 15 Daniil Medvedev, 6-4, 6-7 (5), 6-2, 6-3.
After topping Medvedev in a 3-hour, 15-minute struggle to get back to the quarterfinals for the first time in three years, Djokovic joked during an on-court interview: “Since I guess my next opponent is watching, I’m feeling fantastic. I’ve never felt fresher in my life.”
