Donna Vekic is through to the Wimbledon semi-finals for the first time in her career after coming from behind to beat Lulu Sun.

After losing her previous two grand slam quarter-finals in straight sets, Vekic rallied to beat the qualifier 5-7 6-4 6-1 on Court No.1 on Tuesday.

After a slightly shaky start, Sun held her nerve brilliantly in the fourth game of the opener, holding out through 10 deuces and successfully defending break point three times.

Sun took full advantage of that let-off, getting the all-important break in the 11th game before holding strong to take the first set.

It was a different story in the second, Vekic continuing to show aggression in her serve before finally gaining an edge with her first break and holding out to force a decider.

The Croatian picked up where she left off in the third set, scoring 10 points in a row as she raced to a 3-0 lead, before clinching a second straight break.

Sun, who has spent the most time on court so far in the women's draw, avoided a bagel with her final service game of the match before Vekic finished it off.

She will face Jasmine Paolini or Emma Navarro in the semi-finals.

Data Debrief: Vekic too strong

Vekic is into her first grand slam semi-final on her 43rd major main-draw appearance. In the Open Era, only four players have made their first semi-final after more major appearances.

It is the fourth time at this edition of Wimbledon that Vekic's matches have gone the distance, and the second time she has had to bounce back from losing the first set.

Sun was bidding to become the first qualifier to reach the semi-finals at the All England Club since Alexandra Stevenson in 1999, but she fell just short.
