JOHANNA KONTA overcame a tough start today to beat Ajla Tomljanovic and advance to the quarter-finals of the Brisbane International.

For the second game running the British No. 1 fought back from losing the first set, eventually triumphing 4-6 6-1 6-4.

Konta, fresh from a tough opening round encounter with Madison Keys, struggled to find the same rhythm at the start and had difficulty protecting her usually dominant serve.
