Agnieszka Radwanska is content with her form at the Australian Open ahead of a semi-final meeting with world number one Serena Williams.
The Polish fourth seed moved into her second career semi-final in Melbourne with a 6-1 6-3 thrashing of a poor Carla Suarez Navarro on Tuesday.
The win extended Radwanska's run of wins to 10 matches this year after she clinched the title in Shenzhen to start her campaign.
Radwanska, runner-up at Wimbledon in 2012, said she was pleased with where her game was at.
"I think it's good, reaching the semi-finals here and I won the tournament before," she said.
"Couldn't be better so far."
Williams' win over Maria Sharapova later in the day means Radwanska faces the 21-time grand slam champion in the last four.
Radwanska has won just one set in her eight previous meetings with Williams and hopes her serve - which can be targeted - is at its best.
"I didn't serve that good today. I was trying to be focused on that, especially that it was tough on one side of the court," she said.
"But, definitely, when you play someone like Maria or Serena you're trying more. You have to really go for it."
Suarez Navarro had 45 unforced errors in the quarter-final clash and the Spanish 10th seed blamed fatigue for her struggles.
"Yesterday and the day before I didn't sleep as much as I wanted, I didn't rest good. You know, I feel tired," she said.
"But when you are on court you have to fight, you have to run, you have to be there, and today I didn't have the good feeling to play good tennis, the good mentality to play more aggressive or try to play a little bit better than I play.
"But I have to learn about these situations, this match, this experience. I need to learn."
