Young American Madison Keys has reached the third round at the U.S. Open for the first time.
The 19th-seeded Keys needed just 54 minutes to beat 100th-ranked Tereza Smitkova of Czech Republic 6-1, 6-2 on Wednesday in a matchup of 20-year-olds.
Keys has now advanced to at least the third round at every major this year, which started with her breakthrough run to the semifinals at the Australian Open.U.S. OpenU.S. Open: Women's resultsInfographicSerena and the Slams
Keys, who didn't face a break point Wednesday, could meet Serena Williams in the fourth round.
Before that, she could play 15th-seeded Agnieszka Radwanska, who beat her in three sets in the Wimbledon quarterfinals. Radwanska takes on a fellow Polish player, 91st-ranked Magda Linette, later Wednesday.
