Southern Californian Kayla Day celebrated two milestone achievements on Sunday, Sept. 11 in New York City. The 16-year-old Day, the number five-seed from Santa Barbara, Calif., defeated the 13th-seeded Viktoria Kuzmova of Slovakia, 6-3, 6-2, on the Grandstand Court at the USTA Billie Jean King Tennis Center to capture the U.S. Open Junior girls singles title at the year’s final Grand Slam.

In her post-match press conference, Day was notified that on Monday she would be the new International Tennis Federation world number one-ranked junior girls player.

“These were the best two weeks of my life,” said Day after the match. “Every day was great. I had so much fun every single day, and it was just a great experience overall.”

Day showed amazing resiliency, coming back from a tough three-set semifinal win in singles on Saturday, and then falling in the doubles final later that evening after holding two championship points.

“I think I was really able to mentally set aside what had happened last night and just move on, because I knew I had a really important match today,” Day said. “I knew I had to forget about it, and that's what I did. I think I'm pretty good about, you know, leaving the past behind me and just focusing on being in the moment.”

Day became only the seventh American girl to win the U.S. Open Junior singles title since Lindsay Davenport in 1992, a span of 24 years. She is also the first American to win in Flushing Meadows since 2012 when Samantha Crawford won, and joins a list of champions that includes Grand Slam women’s champions Victoria Azarenka and Jennifer Capriati.
