Australia's Ashleigh Barty claimed the biggest singles title of her career so far with victory over former world number one Karolina Pliskova in Miami.
The 22-year-old will move into the world top 10 - the first Australian to do so since Samantha Stosur in 2013 - after a 7-6 (7-1) 6-3 win.
She hit a career-high 15 aces against the Czech to earn a fourth title.
After a tightly contested first set, Barty dropped just five points in the final four games to seal victory.
The 5ft 5in Australian's win in Florida on Saturday means the first 14 events of the 2019 women's singles season have all been won by different players.
