Cibulkova pulled off her second big upset in as many days with a 6-2, 4-6, 6-3 win over second-seeded Angelique Kerber in the semifinals. Cibulkova defeated third-seeded Sara Errani in the quarterfinals.
Cibulkova had three breaks in the first set and two in the third in gaining her seventh WTA title match. She's 2-4 in previous finals appearances.
Radwanska, who hasn't dropped a set this week, ousted fourth-seeded Li Na 6-3, 6-4. She had five breaks and won 50 percent of the points off Li's serve. It was the first loss this year for Li, who won the tournament at Shenzhen, China, last week.
Radwanska is looking for her second title of 2013 in Friday's championship match, having won the season-opening event in New Zealand last week. She has an 11-4 record in tournament finals.
Radwanska is 3-0 lifetime versus Cibulkova but all of those matches were in 2008.
The Apia International champion will take home $117,000 while the runner-up settles for $62,300. Kerber and Li each won $32,830 as semifinalists.
