Agnieszka Radwanska and Andy Murray picked up morale-boosting victories in the Hopman Cup on Wednesday to keep their Australian Open preparations on track.
World No 5 Radwanska took just 65 minutes in scorching conditions in Perth to defeat Britain's Heather Watson 6-3, 6-1 and continue her winning run in the mixed-team event.
"I played much better than the first match, a couple of days here helped me out with the conditions and getting used to the court and balls," said Radwanska, who had defeated Australian Casey Dellacqua 6-2, 6-3 on Sunday.
"Over the last few days, the goal was to just survive the practice. It was really, really hot and I needed to get used to it, especially since it's the first event of the season."
Murray, ranked sixth in the world, also dismissed concerns about a shoulder niggle by thumping Poland's Jerzy Janowicz 6-2, 6-4 to continue his build-up in his quest for a maiden Australian Open title.
The 27-year-old Scot, who had hurt his shoulder during his triumph in Abu Dhabi last week, started slowly to concede an early break but then won nine games in a row to establish his control on the match.
"I moved well and served good and got a lot of returns back and play so I was happy," said Murray, who beat Frenchman Benoit Paire on Monday.
"My shoulder felt much better today. As I'm playing the matches, it's starting to feel a little bit better."
Radwanska and Janowicz then combined to win the deciding mixed doubles match against Murray and Watson to give Poland their second win in the eight-team tournament.
The Australian Open will be held in Melbourne from January 19-February 1.
