The Latest on the French Open (all times local):
Fourth-seeded Grigor Dimitrov fell to 0-7 against top-50 opponents at the French Open and still has never made it to the fourth round at the clay-court Grand Slam tournament.
Dimitrov, a two-time major semifinalist, bowed out 7-6 (4), 6-2, 6-4 in the third round against Fernando Verdasco, who is ranked 35th and seeded 30th.
In his previous match, Dimitrov had come back after trailing two sets to one and defeated Jared Donaldson 10-8 in the fifth set. That 4-hour, 19-minute victory might have taken something out of Dimitrov.
Verdasco, meanwhile, got to the fourth round at Roland Garros for the seventh time. He has lost at that stage on all six previous chances to reach the quarterfinals.
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.
Still, Keys served for the victory at 5-4, and held a match point at 40-30, when she pushed a backhand long and wound up getting broken. In the tiebreaker, Osaka went ahead 4-1, and held set points at 6-5 and 7-6. Keys held steady, though, and was able to convert her second match point when Osaka double-faulted.
Play has started under overcast skies at the French Open with second-seeded Alexander Zverev and fourth-seeded Grigor Dimitrov both bidding to reach the fourth round for the first time.
Zverev is on Court Philippe Chatrier against Damir Dzumhur, a 26th-seeded Bosnian who is trying to reach the fourth round of any major for the first time.
Dimitrov is playing left-hander Fernando Verdasco on Court 1.
In the women’s draw, second-seeded Caroline Wozniacki will play French wild-card entry Pauline Parmentier on Chatrier.
Also up later is Novak Djokovic, the 2016 champion, against 13th-seeded Roberto Bautista Agut.
