KATIE BOULTER recorded her seventh straight win on the WTA Tour as Camila Osorio retired from their Merida Open clash.

The British Number Three arrived in Mexico on the back of winning the Ostrava Open and overcame issues with her serve to edge past Beatriz Haddad Maia in the opening round.

Boulter, 29, had taken the first set 6-3 when Colombian Osorio called for the physio and decided against continuing the contest.

The victory sees Boulter progress to the last eight, where she will either face top seed Jasmine Paolini or Australia’s Priscilla Hon.

Boulter said in her courtside interview: “Obviously we really don’t want to see women with injuries, it’s been pretty tough recently. I’ve seen a lot of people with them and I’ve been through them myself so I know how difficult it is.

“It’s really not fun, so I wish her the very best. And I hope to see her next week in Indian Wells, and hopefully it’s something small.”

She added: “Obviously, I really love playing in front of a lot of people so it’s really nice to have everyone out here supporting the tournament.

“I’m just happy to be out here and playing more matches.”
