LOS ANGELES:
Britain’s Katie Boulter and Ukraine’s Marta Kostyuk advanced to the WTA San Diego Open final with powerful semi-final triumphs on Saturday, ousting two of the top three seeds.
Boulter, ranked 49th in the world, upset US third seed Emma Navarro 6-3, 6-1 in 74 minutes while sixth-seed Kostyuk ousted US top seed 7-6 (7/4), 6-1.
Each of Sunday’s finalists seeks a second career WTA title. Kostyuk, ranked 34th, won last year at Austin while Boulter took her lone crown at Nottingham last year.
Boulter, whose week in Southern California has included an upset of second-seeded Beatriz Haddad Maia, was in control from the outset against 26th-ranked Navarro, who won her first WTA title in January at Hobart
Boulter broke twice to pocket the first set. She was up 6-3, 1-0 when a sudden shower briefly halted play.
