Serena Williams marched into the semifinals of the US Open for the ninth consecutive time with an assured 6-4 6-3 win over eighth seed Karolina Pliskova Tuesday.
It is the first time the six-time champion has beaten a top-10 opponent since returning from maternity leave and the victory ensured the American got some measure of revenge for her 2016 US Open semifinal loss against the Czech.
The 36-year-old overcame a 4-2 deficit in the first set to see off Pliskova in one hour and 23 minutes and reach the last four at Flushing Meadows for the 12th time in her career.
Williams — aiming to win a first grand slam since giving birth to her daughter last September which would tie her with Margaret Court’s all-time record of 24 major wins — will next play Latvia’s Anastasija Sevastova, who beat defending champion Sloane Stephens 6-2 6-3 earlier Tuesday.
“I was having a baby at this time last year so I really have nothing to prove,” Williams told the Arthur Ashe crowd after the win. “I really feel now that I am playing free.”
‘I felt so bad I wasn’t winning’
Williams struggled at the start of an error-strewn first set — 22 of her 30 unforced errors came in the first set — before going on an eight-game run to secure victory over the 2016 finalist.
After the match Williams said she had taken confidence from the backing of a partisan crowd, which included Billie Jean King, actor Michael Keaton and director Spike Lee.
“The crowd was really for me and I felt so bad that I wasn’t winning,” she said. “I said ‘I got to try even harder.'”
The famed director had told ESPN that Williams ranked among sports’ greats, including Muhammad Ali, Michael Jordan and Joe Namath.
Williams’ coach, Patrick Mouratoglou, said that after a “tight” start the second set “was like a second match.”
Taking down former world No.1 Pliskova was Williams’ toughest test of the tournament so far, having already dispatched her sister, Venus — seeded one higher than Serena at 16 — and the unseeded Estonian Kaia Kanepi, Carina Witthoeft of Germany and Poland’s Magda Linette.
Her last-16 match against Kanepi is the only time any of Williams’ matches thus far have gone beyond two sets.
Though her ranking suffered due to her truncated 2017 season and she came to Flushing ranked 28th in the world, Williams’ dazzling form means she’ll be confident of rising up again.
She could be ranked as high as 11th by the end of play Saturday, should she make 2018 her seventh US Open crown.
