Sloane Stephens of the United States returns a shot to Johanna Larsson of Sweden during her women’s singles second round match on Day Three of the 2014 US Open at the USTA Billie Jean King National Tennis Center on August 27, 2014 in the Flushing neighborhood of the Queens borough of New York City

*It was a short US Open run for Sloane Stephens.

The 21-year-old American had her earliest loss at Flushing Meadows, upset in the second round Wednesday by 96th-ranked Johanna Larsson.

Down a set and a break, Larsson, 26, rallied to win 5-7, 6-4, 6-2 to match her best performance at a major tournament.

Stephens reached at least the fourth round at six straight major tournaments starting with the 2013 Australian Open, when she stunned Serena Williams to make the semifinals. The longest active streak at the time, it ended with a first-round loss at Wimbledon this summer.

On the verge of breaking into the top 10 last fall, Stephens has slid to No. 24 in the rankings.

“Everyone goes through times like this,” she said. “I’m not the first person and won’t be the last.”
