(2) Roger Federer (Switzerland) D. Leonardo Mayer (Argentina) 6-1, 7-6(6)
Multiple W&S Open record-holder Roger Federer claimed sole possession of third place in consecutive tournament match victories with his 13th.
Federer breezed through the first set against in fine fashion connecting on 70 percent of his first serves, winning 93 percent of his first-serve points and 80 percent of his second-return points. He also was 2-for-6 on break opportunities.
Leonardo Mayer hung tough in the second and forced a tiebreak by winning 88 percent of his first-serve points, but struggled returning Federer’s offerings that included seven aces. Mayer won just 13 percent of his first-return points and 20 percent of his second-return points in the set while committing two double faults.
“Today, I tried to really focus on just the one match, not thinking that there is possibly going to be two. But, obviously, I'm very happy with my first round today against Mayer,” the seven-time W&S Open champion Federer said.
He takes a familiar place in the Cincinnati quarters and will take on fellow countryman Stan Wawrinka in the night session.
“Playing Stan obviously is always very special, especially after what we have gone through the last few years with my knee surgery but especially his, which was even bigger and more difficult.
“I'm very happy that he's back. You know, it's been just a bit over 10 years since we celebrated Olympic gold medals together. A lot has happened since,” Federer concluded.
He leads the head-to-head series 20-3, and is 4-1 in the past three meetings. He took the most recent meeting 6-4, 7-5 last season at Indian Wells. He also banked the only Cincinnati meeting in the series 7-6(4), 6-3 in 2012.
Wawrinka’s last series win was 6-4, 6-3, 7-6(4) in the 2015 French Open quarterfinals.
(4) Juan Martin del Potro (Argentina) D. (15) Nick Kyrgios (Australia) 7-6(4) 6-7(6) 6-2
An anticipated inaugural battle of premier power hitters met expectations as Juan Martin del Potro fought his way into his third tournament quarterfinal and first since 2013.
Kyrgios, 23, launched 29 aces and del Potro reeled off 19 in the match while treating the Grandstand crowd to high-level play that sent the opening sets to tiebreakers.
The veteran del Potro, 29, turned the match in the third with stronger service stamina. He delivered on 92 percent of his first-serve points, went 72 percent on first serves and cranked out five aces without a double fault. He solved Kyrgios’ attack by scoring 62 percent of his second-return points.
Kyrgios drilled four aces in the deciding set, but committed three double faults while converting a mere eight percent of his first return points.
“I am happy to beat these young players. He has a big future, and he is a nice player,” said del Potro, who bumps his W&S Open record up to 13-5.
He’ll quickly turn his attention to his evening match against 11th-seeded David Goffin.
(10) Novak Djokovic (Serbia) D. Grigor Dimitrov (Bulgaria) 2-6, 6-3, 6-4
Current Wimbledon champion Novak Djokovic will make his eighth trek to a tournament quarterfinal after derailing Grigor Dimitrov’s W&S Open championship defense in the Round of 16.
The match was the second of the morning on Center Court and resumed with Djokovic leading 2-1 in the third set after he earned a momentous break point off a long rally Thursday night.
He warded off two deep Dimitrov lasers from well behind the baseline - the first with a lob and the second with a driving forehand a lunging Dimitrov deposited into the net. Djokovic carried the deciding stanza winning 81 percent of first-serve points and 71 percent of his second-serve points. He converted 74 percent of his first-serve points in the match.
Both combatants went 3-for-5 on break point opportunities in the match.
Djokovic improved his Cincinnati record to 29-11 and now owns the most tournament victories by a player who has yet to capture a Rookwood Cup.
He’s set to face Canadian Milos Raonic for the first time in two seasons in today’s afternoon quarterfinal. Djokovic leads the head-to-head series 8-0.
(1) Simona Halep (Romania) D. Ashleigh Barty (Australia) 7-5, 6-4
World No. 1 and top-seeded Simona Halep claimed an open tournament quarterfinal spot for a sixth time by getting past Ashleigh Barty for the second straight week in a rematch of a Montréal semifinal.
Halep bounced back from two games down in the first set to take the closing three. She was successful on 79 percent of her first serves in the frame.
She erased a two-game deficit again in the second set by capturing four straight games and delivering on 80 percent of her first serves.
Halep credited her successful effort in part to a key tactical adjustment.
“I feel like she missed more than me and when I started to play more on the backhand to make her move, it was better for me. She’s a tough opponent because she’s always mixing the rhythm,” she said.
She’ll tangle with Lesia Tsurenko in a Stadium 3 quarterfinal this evening. The two last met at Wimbledon in 2014. Halep owns a 4-0 advantage in the series.
“I’m really happy I can go through with this and tonight I’ll have another match,” Halep said.
(5) Elina Svitolina (Ukraine) D. (WC ) Amanda Anismova (USA) 6-4, 6-4
Twenty-three-year-old world No. 7 Elina Svitolina eliminated the youngest player in this year’s main draw, 16-year-old Amanda Anismova, to advance to a third tournament quarterfinal since 2014.
Svitolina was out served by her younger opponent, but took two of three break opportunities and capitalized by winning 43 percent of her second return points in the match.
The Ukranian fell to Sloane Stephens in last week’s Montréal semifinal and will vie to reach her second overall and first Cincinnati semifinal since 2015 when she clashes with Netherlands’ Kiki Bertens tonight.
Anisimova draws the curtain on a reputable 2-1 Cincinnati debut owning a piece of W&S Open history.
She became the youngest female player (16 yrs., 353 days) to win a main draw match since the WTA returned to here in 2004 by taking out Hungarian Timea Babos 6-3, 6-4 in the opening round.
