WIMBLEDON, England -- From the red clay of the French Open to the green grass of Wimbledon, the wins keep coming for Iga Swiatek.
The top-seeded Pole won her opening match on Centre Court on Tuesday, beating Croatian qualifier Jana Fett 6-0, 6-3.
The victory was Swiatek's 36th in row and includes all seven matches she played at this year's French Open in winning her second title at Roland Garros. It's the longest winning streak on the women's tour since 1997, when Martina Hingis won 37.
"It's my first match on grass this season, so I knew it's going to be tricky," Swiatek said on court. "I'm just figuring out how to play here and trying to implement all the stuff that we were practicing on."
Gauff got the go-ahead break in the third set at 5-5 on her sixth break point of the game when Ruse double-faulted.
In her two previous appearances at the All England Club, Gauff reached the fourth round.
Even with seven-time champion Serena Williams in the draw at the All England Club, Swiatek is the woman to beat. She won five tournaments before heading to Paris in May, earning consecutive titles in Doha, Indian Wells, Miami, Stuttgart and Rome.
Swiatek, again wearing a pin with the colors of Ukraine on her hat, started out like she left off in her last match at the French Open. But she went down 3-1 in the second set before recovering.
"The second set, at the beginning I lost my focus a little bit and she used that pretty well," Swiatek said.
Two-time Wimbledon champion Petra Kvitova, who came into the tournament after winning the grass-court tune-up event at Eastbourne, beat Jasmine Paolini of Italy 2-6, 6-4, 6-2. Kvitova won the title at the All England Club in 2011 and 2014.
