Fourth seed Jessica Pegula is having a strong debut in Brisbane, and in the semi-finals, she will take on 16th seed Marta Kostyuk. This marks their sixth career meeting, and below is our prediction for the match.
Pegula has contested 20 tour finals in her career. With a dominant past against Kostyuk, Pegula will be confident of adding to the strong record.
The American has won four of five meetings with Kostyuk. Last year, she defeated Kostyuk twice, with one of those victories coming on her way to the Miami final.
Pegula defeated 10th seed Liudmila Samsonova in the quarter-finals in straight sets. It was the world number six’s first 2-0 win of the season after starting the campaign needing a decider in back-to-back matches.
Marta Kostyuk’s only win against Pegula came in a similar round in San Diego two years ago. Though not possessing a dominant record when it comes to competing in the latter stages of tour tournaments, Kostyuk will fancy a second semi-final victory over Pegula.
Now up five places to 21st in the live ranking, Kostyuk has won against two seeded players this week.
She beat second seed Amanda Anisimova in the second round and then saw off sixth seed Mirra Andreeva in the quarters. In both victories, Kostyuk battled to win in straight sets.
