Sloane Stephens took to Twitter on Thursday for a Q&A session with fans on behalf of her kit sponsor, Under Armour.

The No. 2 American behind Serena Williams, Stephens made her top 15 debut this week and is set to return to competition next week at the Citi Open in Washington, D.C., where she'll begin her three-tournament preparation for the U.S. Open. She's also scheduled to play the Rogers Cup in Toronto and the Western & Southern Open in Cincinnati.

Stephens is looking to keep her exemplary 2013 Grand Slam results going in New York. She's made the fourth round or better at the first three majors, including the semifinals of the Australian Open and the quarterfinals of Wimbledon, where she lost to the eventual champions in both instances.

Here are some of the highlights from Stephens' tweet-fest. She talks about shopping and haters and challenges John Isner to a serve-off: Isner's response: "Bring it Sloaney!"
