Tradition of Excellence

Sofia Kenin
​
Who would have imagined that only five years later, the 2015 IOSC champion would capture her first Grand Slam title in Melbourne at this year's Australian Open, then lead the United States Fed Cup team to the tournament final!
Sam Querrey
​
A champion here in 2005, Sam has long been among the top American men on the ATP Tour. He has won ten titles on tour and reached the semifinals at Wimbledon in 2017, and reached the quarters at the US Open that same year. 
​
Sloane Stephens
​
After winning this event in 2009, Sloane Stephens went on to reach a high ranking of #3 on the WTA Tour. In 2013 she upset Serena Williams at the Aussie Open, and four years later was crowned US Open singles champion.
