Top-ranked Simona Halep, third-seeded Garbine Muguruza and two-time champion Maria Sharapova all powered into the French Open's third round with straight-set victories Thursday.
Halep showed no signs of fatigue in beating wild-card entry Taylor Townsend 6-3, 6-1, despite playing on consecutive days.
Sharapova improved to 13-0 in second-round French Open matches by beating 50th-ranked Donna Vekic of Croatia 7-5, 6-4.
And Muguruza impressed with her easy movement around the court in a 6-4, 6-3 victory over French wild-card entry Fiona Ferro.
Halep broke the 72nd-ranked Townsend in the first game and jumped to a 5-1 lead.
Townsend dug deep in the eighth game, with Halep serving for the set, clawing back a break to slow the progress of last year's losing finalist.
Halep swiftly quelled the rebellion. Heaping pressure on Townsend's serve at 5-3, she earned herself two set points and converted the first, with a forehand winner from the baseline.
Halep tightened the squeeze in the fourth game of the second set. Townsend saved three break points, but hit a backhand long to give Halep a 3-1 lead.
From there, Halep's serve and shots that pulled Townsend around the Court Philippe-Chatrier finished the job.
She served out the last game to love, breaking into a smile after a winning volley at the net that brought up three match points.
Halep said in her post-match interview that she struggled initially against the left-hander's shots with topspin. But the score didn't show it.
Her next opponent, Andrea Petkovic of Germany, beat Bethanie Mattek-Sands 6-0, 7-6 (5) to reach the third round.
Sharapova took a bit of time to close out her match on Court 1. She led 5-2 in the second set, then served for the win at 5-3, but was broken when she sailed an off-balance forehand wide.
She broke right back to end it, though, converting her fifth match point with a forehand return winner.
Sharapova is competing at Roland Garros for the first time since 2015. She missed the clay-court Grand Slam tournament in 2016 while serving a doping suspension, then was denied a wild-card entry by the French tennis federation last year, when her ranking was too low to earn automatic entry.
The 31-year-old Russian won the title in 2012 and 2014, part of her career Grand Slam. She is seeded 28th this year.
Next for Sharapova is a matchup against sixth-seeded Karolina Pliskova. She reached the third round with a 3-6, 6-4, 6-1 victory over 2015 French Open runner-up lucie Safarova.
