Agnieszka Radwanska is yet to lose a match this year, but the Australian Open fourth seed is refusing to get carried in her quest for a maiden grand slam crown.
Radwanska preserved her 100 per cent record in 2016 with a 6-4 6-2 second-round win over former world number five Eugenie Bouchard at Melbourne Park on Wednesday.
The 2012 French Open runner-up is seven-from-seven this year, having won the Shenzhen Open in January.
And while she is confident amid her winning streak, Radwanska, who won the season-ending WTA Finals, remains grounded.
"I'm happy that I'm still playing the same tennis I was playing at the end of the year," the Pole said.
"This is a new season, new tournament. I think it doesn't really matter what happened last year. We already started a new season.
"Of course, I'm confident about my game and I really feel good on court. But it's not sure I'm going to win the match. So I still need to work hard on that. Nothing's going to come for free."
Of her fit-again opponent Bouchard, Radwanska said she was relieved to get past the unseeded Canadian, who is nearing her best after suffering concussion last year.
Bouchard led 4-2 in the opening set before Radwanska reeled off four consecutive games.
Radwanska added: "There is always someone in the draw not seeded that you normally play in the second round or even first round. Of course, she's one of those players that should have ranking little bit. She is very dangerous in the draw.
"That was a great challenge for me to play somebody like Eugenie in the second round.
"But I think I was doing everything right today. That's why I won that match in two sets. Definitely not an easy draw."
