Stephens is trying to become just the fourth unseeded woman to advance to the U.S. Open semifinals in the Open era, which began in 1968. Williams was the first, in 1997.

U.S. Open semifinalist Juan Martin del Potro and two-time Wimbledon champion Petra Kvitova have won the U.S. Open sportsmanship awards.

U.S. Tennis Association chairman and CEO Katrina Adams says del Potro and Kvitova have “not only captivated us at this year’s U.S. Open, but shown incredible class in doing so.”

Del Potro has overcome injuries and illness to reach the men’s semifinals after beating five-time champion Roger Federer on Wednesday. Kvitova lost a close match to Venus Williams in the women’s quarterfinals after missing much of the first half of the season while recovering from hand injuries suffered during a knife attack in the offseason.

Each player received a trophy and a $5,000 donation to the charity of his or her choice. To be eligible, players had to compete in at least two U.S. Open series events, as well as the U.S. Open.
