Iga Swiatek soared into the second round at Wimbledon after beginning her latest quest for a maiden grass-court major title with a straight-sets win over Sofia Kenin.

The top seed, who is aiming to progress beyond the quarter-finals at SW19 for the first time, prevailed 6-3 6-4 in the battle of the grand slam champions after 79 minutes on No.1 Court.

Swiatek had won the two previous meetings between the players, both of which came at major events – in the 2020 French Open final and this year's Australian Open first round.

The four-time Roland-Garros winner made a statement of intent, breaking her opponent twice in her first two service games on the way to taking the opening set.

Former Australian Open champion Kenin, who stunned Coco Gauff in the first round 12 months ago, looked to respond and forced a break-point opportunity at 4-3 down in the second set.

However, the American saw it go begging as she sent a forehand into the net, and the set remained on serve as Swiatek set up a second-round clash with Croatia's Petra Martic.

"On this surface, it's not about the result for me, [it's] about the progress," the Pole said in her on-court interview. "I'm just trying to be better every day.

"It was a solid start and not an easy draw, so I'm happy that I have a chance to play another match here. It's not easy to play a Grand Slam champion in the first round, so we have to be ready for everything.

"Obviously, I had a great beginning of the season, so I feel like I can come here and not worry about points or anything, and just focus on what I want to focus on. These are experienced players, so there’s no time to get into the tournament."

Data Debrief: Super Swiatek matches Henin and Radwanska

Swiatek arrived at Wimbledon with five titles to her name already this season, including three on the spin in Madrid, Rome and the French Open.

The world number one has now won each of her last 20 matches, achieving that feat for the second time in her career. Justine Henin in 2005 was the last player to register multiple streaks of 20+ WTA match wins before turning 24.

Notching her fifth straight victory over a former major champion, Swiatek has now registered 72 grand slam singles wins, more than any other woman since the turn of the century.

She is also only the second player in the Open Era to win in the opening round of all the first 18 major events in a single decade, after compatriot Agnieszka Radwanska did so in the 2010s.
