Katie Boulter set for biggest ranking rise yet after landmark San Diego Open run after being ranked in top 150 a year ago

Katie Boulter is set for a huge rise in the WTA rankings after her run at the San Diego Open. Boulter is in the semi finals of the WTA 500 event after defeating second seed Beatriz Haddad Maia in the last 16, before victory against Donna Vekic in straight sets.

"It was an absolute battle in tricky conditions, it was not easy to get any rhythm as we are both big hitters,” Boulter said in her on-court interview.

"Somehow found a way over the line in the first, then played some really good stuff in the second."

Boulter is now provisionally number 43 in the world, with a chance to go even higher than that if she beats Emma Navarro in the last four.

It marks an incredible rise for the 27-year-old, who in 2023 was competing mainly in the ITF World Tour, at World No. 157, before winning her first WTA title in Nottingham last June.

Boulter admits she hasn't set any major goals. "I’ve got quite a few goals for next year which might be a good thing or a bad thing. I’m not really huge on rankings goals, I’m more of a process person.

"It was about pushing past my career high. I wanted to get closer to (the top) 50 so I had small mini-goals through the year, but I wouldn’t say I had a massive goal."
