San Diego Open: Katie Boulter of Britain won the second and highest-level WTA Tour title of her career, fighting past No.6 seed Marta Kostyuk of Ukraine 5-7, 6-2, 6-2 to claim the San Diego Open crown.

Boulter needed 2 hours and 13 minutes to power past Kostyuk in their first meeting and notched her first WTA 500 title on Sunday night.

The Briton's previous title came last summer, when she triumphed in her home country on the grass courts of WTA 250 Nottingham.
