Konta's bid to retain Sydney title is ended in opening round
Johanna Konta saw her Sydney International title defence swiftly ended as she lost to Agnieszka Radwanska in the first round.
A slide in the rankings to 28th meant former World No.2 Radwanska entered this week as an unseeded player, but she showed her quality in a 6-3 7-5 victory.
In a repeat of last year's final, fourth seed Konta could not take control against Poland's former Wimbledon runner-up.
Consolation for Konta came with the fact she completed the match without obvious physical problems, five days after being forced to retire from her Brisbane International quarter-final with Elina Svitolina due to injury.
She now heads for Melbourne and the Australian Open, where 12 months ago she reached the quarter-finals, while Radwanska continues her Grand Slam preparation in Sydney and faces American teenager CiCi Bellis next.
Radwanska said: "I'm just so happy to play such a great match before the Australian Open.
"It was a top-10 level match with some ups and downs, but I'm happy to win in two sets."
Venus Williams was the casualty of a heavyweight second-round clash with Germany's former World No.1 Angelique Kerber, starting well but running out of steam in losing 5-7 6-3 6-1.
Rain had held up play after wins for Slovakian Dominika Cibulkova, Czech Barbora Strycova and Australian Samantha Stosur.
