U.S. Open: John Isner, last of American men, eliminated

Once again, John Isner’s trip to Flushing Meadows ended in the third round. Once again, it happened with a loss to Germany’s Philipp Kohlschreiber at that stage.

And once again, there are zero American men in the U.S. Open’s round of 16 – something that had never happened until it did last year at the country’s tennis championship, which was first played in 1881.

On a windy, cloudy Saturday evening, the 13th-seeded Isner hit 42 aces, saved all five break points he faced – and yet it wasn’t enough. Unable to capitalize on plenty of openings, and surprisingly outplayed in a trio of tiebreakers, Isner lost to the 22nd-seeded Kohlschreiber 7-6 (4), 4-6, 7-6 (2), 7-6 (4).

“It’s disappointing for me personally – not for America as a whole,” Isner said.

It was the third straight year that these two men faced each other in the third round in New York. Kohlschreiber eliminated Isner in five sets in 2012, and in four sets in 2013.

Isner only converted 1 of 12 break points he accumulated.

Williams keeps winning

Bidding for a third consecutive U.S. Open title, Serena Williams moved into the fourth round by beating 52nd-ranked Varvara Lepchenko 6-3, 6-3.

The No. 1-ranked and No. 1-seeded Williams has faced American opponents in all three of her matches this week while extending her overall winning streak at Flushing Meadows to 17.

Kvitova upset

Wimbledon champion Petra Kvitova is out in the third round of the U.S. Open.

The No. 3-seeded Czech committed 34 unforced errors in a 6-4, 6-4 loss to Aleksandra Krunic, a Serbian qualifier ranked No. 145.

Djokovic beats Querrey

Novak Djokovic’s routine 6-3, 6-2, 6-2 victory against Sam Querrey put him in the round of 16 at a 22nd consecutive Grand Slam tournament.

Murray overcomes lull

Eighth-seeded Andy Murray beat 96th-ranked Andrey Kuznetsov of Russia 6-1, 7-5, 4-6, 6-2. Murray double-faulted to drop the fourth set.

No. 1 Errani-Vinci out

A day after beating Venus Williams in singles at the U.S. Open, Italy’s Sara Errani and her partner, Roberta Vinci, were knocked out in the second round as the top-seeded team in women’s doubles.

Errani and Vinci, who were 2012 champions at Flushing Meadows, lost 6-4, 1-6, 6-4 to Jarmila Gajdosova and Ajla Tomljanovic of Australia.
