NEW YORK — Wilting in high heat and humidity, Eugenie Bouchard became the latest top woman to lose at the U.S. Open, ending her streak of making the semifinals at each Grand Slam tournament this year.
The No. 7-seeded Bouchard, the runner-up at Wimbledon in July, needed a medical timeout and was beaten 7-6 (2), 6-4 Monday by 17th-seeded Ekaterina Makarova of Russia.
In muggy air with temperature in the high 80s (above 30 Celsius), a trainer checked Bouchard's blood pressure and rubbed plastic bags of ice on her shoulders, arms and legs during the changeover after the second set's fifth game.
Bouchard's loss means that for the first time since 1977, eight women will have filled the eight finalist slots at a season's Grand Slam tournaments.
While Makarova is into the U.S. Open quarterfinals for the second year in a row, Bouchard's early-for-her major exit certainly fits with the way things have gone the past eight days. Of the top 10 seeded women, only two remain: No. 1 Serena Williams and No. 10 Wozniacki.
Williams got to her first Grand Slam quarterfinal of 2014 by overwhelming 50th-ranked Kaia Kanepi of Estonia 6-3, 6-3 Monday, winning her first 12 service points with the help of five aces.
Through four matches, Williams has lost only 17 games — the eighth time she's made it to the U.S. Open quarterfinals dropping that many or fewer.
Next for Williams is 11th-seeded Flavia Pennetta of Italy, who beat 29th-seeded Casey Dellacqua of Australia 7-5, 6-2.
The top-seeded man, Novak Djokovic, played mostly mistake-free tennis, making only 19 unforced errors and facing only two break points — both saved — in a 6-1, 7-5, 6-4 victory over 22nd-seeded Philipp Kohlschreiber of Germany.
Djokovic, the 2011 U.S. Open champion, earned a spot in the quarterfinals at the U.S. Open for the eighth year in a row — and at a 22nd consecutive Grand Slam tournament overall. The last time Djokovic was eliminated before the quarterfinals at a major was a third-round loss to Kohlschreiber at the 2009 French Open.
Djokovic now meets No. 8 Andy Murray, who got past No. 9 Jo-Wilfried Tsonga 7-5, 7-5, 6-4.
