Caroline Wozniacki had a special guest in attendance at the U.S. Open Tuesday.
Former Yankees captain Derek Jeter was in the stands for the No. 4-seed Wozniacki's first-round match against Jamie Loeb at Arthur Ashe Stadium at Billie Jean King National Tennis Center.
The retired shortstop was shown on the stadium's JumboTron before the end of the first set and received a loud cheer from the fans in attendance as Jay Z's "Empire State of Mind" played in the background.
After Wozniacki won the first set, 6-2, stadium security whisked Jeter away to a private suite as fans followed and snapped photos. Jeter declined to speak with reporters before entering the suite.
Wozniacki went on to win the match, 6-2, 6-0.
Jeter retired from the Yankees last season. Shortly after retiring, he founded The Players' Tribune, a website on which athletes can share first-person thoughts and stories. Wozniacki made her debut post for the site as a senior editor Monday.
