London - Britain's Johanna Konta reached the Wimbledon third round for the first time Wednesday with a 7-6 (8/6), 4-6, 10-8 win over Donna Vekic which left her opponent in tears.
The 26-year-old Konta triumphed after three hours and 10 minutes in the sweltering Centre Court heat and goes on to face Maria Sakkari of Greece for a last-16 spot.
With Heather Watson having also made the last 32, it is the first time since 1986 that two British women have reached the third round at Wimbledon.
Vekic, watched by boyfriend Stan Wawrinka, the men's world number three, was inconsolable in defeat having squandered break points in the 17th game of the deciding set.
"It hasn't quite sunk in. I feel very fortunate to have come through that," said Konta, who had lost to the 21-year-old Croatian in the Nottingham grass court final last month.
"I overall trusted my game a bit more against her this time. I think the quality of the match today was very high. I'm definitely here with the intention of wanting to be part of the event for the full two weeks."
Konta fired 55 winners to Vekic's 42 in the gripping second round clash.
