Swiatek hits straight-sets win to secure perfect Italian Open start
World number one Swiatek looked in exceptional form as she demolished Pavlyuchenkova 6-0, 6-0 in just over an hour to ease her way into the third round in Rome.
Losing finalist in Madrid last weekend, Swiatek looked in great form in the tournament she won last year before going on to blitz the French Open.
Swiatek now faces either Bernarda Pera or Lesia Tsurenko in the last 32 after extending her winning streak in the Italian capital to 12 matches.
The only real resistance from Pavlyuchenkova, who reached the final of Roland Garros two years ago, came in the final game of the first set, when she saved six set points from 0-40 down on her serve.
Swiatek eventually came through that game and swept Pavlyuchenkova aside in the second set, finishing the job against the serve with her first match point.
Earlier, Jannick Sinner cruised into the men's last 32 with a straight-sets win over Thanasi Kokkinakis, 6-1, 6-4.
World number eight Sinner took one hour, 18 minutes to deal with Australian qualifier Kokkinakis, and will now play Russian Alexander Shevchenko, who beat Argentinian Sebastian Baez 6-3, 6-4.
"I'm happy with my level today, it was not easy, it was a little bit breezy, a bit windy," Sinner said on court.
"Especially in the second set he played a little bit better. I also had a couple of chances which I didn't use but very happy about how I served, I struck the ball very well."
