Katie Boulter advanced to the Mexico Open quarter-finals on Thursday after Camila Osorio was forced to retire from their match.
Osorio, who won the Philippines Women’s Open last month, was trailing 3-6 when she was forced to retire due to an injury.
For Boulter, her hot streak continued on Thursday and she has now won seven consecutive matches on the WTA Tour.
Following Thursday’s contest in Merida, Boulter offered her support to Osorio, who is set to rise one place in the WTA rankings despite the loss.
Katie Boulter hopes to see Camila Osorio in Indian Wells after the Colombian’s injury
“Obviously we really don’t want to see women with injuries, it’s been pretty tough recently,” Boulter said on-court after the match.
“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.”
Boulter 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.”
With victory on Thursday, Boulter potentially set up a clash with top seed Jasmine Paolini in the Mexico Open quarter-finals.
Paolini, who was recently stunned by Alexandra Eala in Dubai, faces Priscilla Hon in the Mexico Open second round.
Boulter has a serious opportunity to advance further in Mexico if she faces Paolini. The Italian has struggled to start 2026, losing her opening match at her last three tournaments.
Boulter has a 2-3 record against Paolini, last playing the Italian at the 2025 Madrid Open. Paolini won that round of 64 contest 6-1, 6-2

Boulter struggles with her first serve again
Boulter has struggled to land her first serve in Mexico: during her first-round match against Beatriz Haddad Maia, the British star made only 36 per cent of her first serves.
On Thursday, Boulter again struggled to find her range, landing only 42 per cent of her first serves.
Boulter mitigated her first-serve struggles by imposing her will during baseline exchanges. The British number three won 70 per cent of her first-serve points and 58 per cent of her second-serve points.
However, the British star will need to land her first-serve more frequently against Paolini, who is an excellent all-around player.
If Boulter wins her quarter-final match in Mexico, she will face either Cristina Bucsa, Ann Li or Zeynep Sonmez in the semi-finals.
