Madison Keys secured her third WTA Tour title after defeating Coco Vandeweghe in the final of the Bank of the West Classic.
American third seed Keys outslugged countrywoman Vandeweghe 7-6 (7-4) 6-4 in Stanford on Sunday.
After upstaging Wimbledon champion and top seed Garbine Muguruza in the semi-final, Keys continued where she left off as she struck 23 winners and 19 unforced errors.
Keys - crippled by wrist injuries over the past year - saved all three break points she faced, sealing the title in one hour, 28 minutes.
The 22-year-old adds her Stanford crown to victories at the Birmingham Classic and Eastbourne International.
