Johanna Konta holds her nerve to beat Australian No 3 Ajla Tomljanovic

On Monday Katie Boulter became the first player in Australian Open history to win an elongated sudden death tie-break, and Jo Konta followed her in doing exactly the same thing to make the second round.

The British No 1 carved out a gutsy 7-6 2-6 7-6 win over Australia’s Ajla Tomljanovic when she came through a nerve shredding shootout 10-7.

Unlike with Boulter, there was no confusion in this match about it finishing under the new format adopted this year.

Konta began the tie-break attempting several dropshots that backfired and saw a 2-0 lead become 2-4. But having got back to 7-7 she then reeled off the last three points, sealing victory with a cross court forehand winner.

While not reaching her levels of a two years ago this will be a morale-boosting win for Konta, who must now face Garbine Muguruza after the former Wimbledon champion beat China’s Saisai Zheng 6-2, 6-3. Konta is the third GB player into the singles second round after Boulter and Dan Evans.

This tournament has historically been a good one for Konta, having made the quarter and semi-finals before, and she was desperate to make another run to kick start her year.

The match between Konta and Australian Tomljanovic attracted a large crowd on Court 3

Facing the world No 47, who is also known as the longstanding girlfriend Nick Kyrgios, Konta got off to a poor start, going 3-0 down before breaking back and taking the first set to a tie-break.

That was tight as well, but the British No 1 opened up an advantage when on 5-4 she hit a rasping cross court backhand to create a set point, which was immediately converted.

Konta got into trouble in the second set by making a horrendous hash of a putaway volley to be broken for 2-4. She could have broken back for 3-4 from 15-40 but was held off and the rangy Australian levelled the match.

The British player made her life more difficult by only converting one of nine break points but is in the second round after battling hard for two hours and 51 minutes.
