World number one Iga Swiatek claimed her eighth title of 2022 by beating Donna Vekic 6-3 3-6 6-0 in the San Diego Open final.
Vekic, who had finished her rain-interrupted semi-final against American Danielle Collins earlier on in the day, pushed Swiatek but faded at the end.
"It was a really tight match and pretty long," Swiatek said.
"We felt the intensity for sure. At the end I wanted to be the one who played the last ball in."
Swiatek broke Croatia's Vekic in the sixth game and held twice to capture the first set.
