BRISBANE, Jan 10 (Reuters) - Defending champion Aryna Sabalenka outclassed Karolina Muchova to seal a 6-3 6-4 win at the Brisbane International on Saturday and reach the final of the Australian Open tune-up tournament for the third straight year.
In Sunday's title clash, the Belarusian will face Ukrainian Marta Kostyuk, who cruised past world number six Jessica Pegula 6-0 6-3 for her third straight top-10 win after also defeating Amanda Anisimova and Mirra Andreeva in her last two rounds.
World number
one Sabalenka has been in similarly superb form in her first tournament of the season, and arrived for her match against Muchova having defeated reigning Melbourne Park champion Madison Keys in straight sets in the quarter-finals.
Things were expected to be trickier against Muchova, who is known for her inventive brand of tennis and had racked up a 3-1 career head-to-head record over Sabalenka, including victories in their previous three meetings.
Sabalenka shrugged off that statistic to take full control of the semi-final clash with a break in the second game, before she displayed deft touches and power from the baseline to take the first set, which she finished with a huge backhand winner.
The four-times Grand Slam champion, who is eyeing her third Australian Open trophy when the tournament begins on January 18 at Melbourne Park, was pushed harder in the next set but edged ahead again at 5-4 to wrap up the win on serve.
"There were a lot of close misses at the end of the second set but I'm super happy to close this match in straight sets," said Sabalenka, who prevailed on her fourth match point.
"She's a great opponent and I knew that if I gave her that opportunity in the last games, she would take it, and it would be a bit trickier to play. I'm super happy I got the win."
Three Americans were in action in the Brisbane men's event semi-finals, where Brandon Nakashima beat Aleksandar Kovacevic 7-6(4) 6-4 before their compatriot Alex Michelsen went down 6-4 6-2 to top seed Daniil Medvedev of Russia.
In the Auckland Classic, Filipina Alexandra Eala squandered a match point to allow China's Wang Xinyu to secure a 5-7 7-5 6-4 win. Up next for Wang is Elina Svitolina, who beat Iva Jovic 7-6(5) 6-2 in the second semi-final.
Top seed Lorenzo Musetti reached the final of the Hong Kong Open, beating Andrey Rublev 6-7(3) 7-5 6-4 in a last-four clash. Alexander Bublik beat Marcos Giron 3-6 6-4 6-2 in the second semi-final, setting up a title clash with Musetti.
