Iva Swiatek says it is "pretty special" to have matched Martina Hingis' run of 37 victories in a row after coming through a tough test with Lesley Pattinama Kerkhove.

The world number one was taken to three sets by lucky loser Kerkhove in Thursday's second-round tie at Wimbledon but came out on top 6-4 4-6 6-3 on Court No. 1.

Swiatek overtook Monica Seles' career-best 36-match winning streak with her latest triumph and can surpass Hingis with victory over Alize Cornet in the next round.

That would see the Pole hold the record for the most successive victories on the WTA Tour since 1990, something she would take great pride in.

"I think another match to this number [37] is pretty special for me, but you know, when I'm out there, I'm not really thinking about that," she said in her on-court interview.

"I'm just trying to play the best tennis possible on grass, and the result is going to come. I don't have full influence in it, but I'm happy that [the winning streak] is 37.

"Now I'm going to do my best to get even more."

Swiatek still has some way to go to match the all-time winning run, with the record held by Martina Navratilova (74 in a row during 1984).

The two-time French Open winner was far from her best against world number 138 Kerkhove in a match lasting more than two hours that saw her broken three times.

She dropped a set for just the seventh time during her incredible run, which stretches back to defeat against Jelena Ostapenko in mid-February.

In doing so, Kerkhove became the lowest-ranked player to win a set against the number one female in the world since Carla Suarez Navarro – also ranked 138 – against Ash Barty at Wimbledon last year.

"She played a really great match, and it seemed that she really understood how to play today," Swiatek added. 

"But I'm really happy that I could sometimes just fight back and be the last one to play that ball in. I'm pretty happy that I'm going to have another chance to play here."

Swiatek has now won 46 matches this year in total. In the entirety of the 2021 season, only Anett Kontaveit and Ons Jabeur (both 48) won more matches.

Up next is former world number 11 Cornet, who is playing her 62nd consecutive grand slam tournament, which ties Ai Sugiyama for the Open Era record.
