Serena Williams said she was close to accessing the sporting "zone" during her emphatic 6-2, 6-1 victory over Anastasia Pavlyuchenkova in the final of the Brisbane International on Saturday.
Williams needed only 51 minutes to beat the Russian in an ominous warm-up for the Australian Open that begins in Melbourne next week.
"I feel like right now I'm playing some of my best tennis," the American said. "I feel like I want to do better and play better still.
"I've been in the zone a few times. I don't know if I was in the zone today, but I was definitely heading in that direction. I've been in the twilight zone before, where I just felt so good I couldn't do anything wrong."
Andy Murray said he is ready to defend his Brisbane title after an injury to Kei Nishikori handed him a place in today's final.
Murray, the top seed, was in control of the last-four clash at 6-4, 2-0 ahead when Nishikori was forced to retire with a knee problem.
The US Open champion will meet first-time finalist Grigor Dimitrov, who defeated former Australian Open finalist Marcos Baghdatis 6-3, 5-7, 7-6. "I've served pretty well for the majority of the tournament and I've moved better every single match," Murray said.
"Grigor plays with a lot of variety and he can play a lot of shots."
