Jovanovski, the only seeded player to make the semifinals, rolled past Maria-Teresa Torro-Flor 6-2, 6-2 in 65 minutes. Jovanovski won two-thirds of the points on serve and 55 percent when receiving serves.
She dropped just one of the two break points she faced while piling up five breaks in Torro-Flor's eight games serving.
Govortsova defeated Mandy Minella 6-2, 7-5 also with five breaks and winning 55 percent of the points when Minella served. Govortsova lost her serve once in each set but the late break in the second set moved her into her fourth WTA title match.
However, she is 0-3 in her previous championship appearances, with the most recent coming in April 2010. Jovanovski is in her second finals, having won the Baku Cup in Azerbaijan in July 2012.
Saturday's title match will be the first WTA meeting between Jovanovski and Govortsova.
