PARIS (AP) - U.S. Open runner-up Madison Keys overcame some late-match shakiness to reach the fourth round at Roland Garros for the second time in three years.
The 13th-seeded American built a big lead then barely avoided getting pushed to a third set before beating 21st-seeded Naomi Osaka of Japan 6-1, 7-6 (7) in a matchup of powerful baseliners.
Keys compiled a 30-8 edge in winners and started quickly, going up by a set and a break at 3-1 in the second. But she began making more and more mistakes, allowing Osaka to take 10 consecutive points and three games in a row during one stretch.
