Jelena Ostapenko on Friday battled into the women's decider of the Adelaide International.
Ostapenko beat Russia's Ekaterina Alexandrova 6-2, 7-6 (7/3), a victory that will propel the Latvian back into the top 10 for the first time in six years when the new rankings are released on Monday.
Currently ranked 12, the former French Open champion will vie for the title against with Russian, Daria Kasatkina, who earned a walkover win when American second seed Jessica Pegula withdrew with illness.
"She can serve big and was hitting great," Ostapenko said of Alexandrova. "But I was just trying to play my game.
"I'm glad I won in two sets. I've been trying to play more aggressive. It's something we've been working on. I'm feeling good and looking forward to the final."
Ostapenko is bidding for a seventh career trophy.
