(NEW YORK) -- Serena Williams finally avenged her major loss to Sloane Stephens, defeating her 6-4, 6-1 on Sunday to advance to the quarterfinals of the U.S. Open. Stephens topped Williams in the quarterfinals of the Australian Open back in January.
"I definitely think it was a high-quality match," Williams said after the match. "We both came out today to play."
Williams was able to serve big and control points against the 20-year-old Stephens. After a 4-4 first set, Williams won eight of the final nine games.
"When you give her that opportunity to take that step forward, she definitely makes her move," Stephens said. "Unfortunately, today she made her move. I just couldn't get back in."
