Danielle Collins won her 10th match in a row to claim the title at the WTA event in California’s Silicon Valley, defeating Daria Kasatkina 6-3, 6-7(10), 6-1.
It was the fourth final this season for Collins, who pounded a dozen aces and broke her Russian opponent five times in the Sunday showdown.
The winner, ranked 36th, picked up her straight second career trophy after winning on clay in Palermo three weeks ago.
Victory came after the American had lost two previous matches with Kasatkina.
“It was one of my goals to win a tournament this year, and to now win two, it’s just been incredible,” Collins said. “It’s hard to comprehend that I’ve won two back-to-back.
“Today I executed my game plan well. It’s tough against an opponent who runs down so many balls, anticipates so well.
“You sometimes have to win the point six, seven, eight times. Dasha is a great mover and anticipator.”
Collins faced a huge struggle in the second set, with Kasatkina saving five match points and taking the final into a deciding set.
But the American regained control in the third set to end it on her seventh winning chance.
“Towards the end of the second set, I became too much of my own critic as well, and I was really hard on myself,” Collins said.
“I really had to have a reality check after losing that tiebreak, and (told myself) to keep the positive energy going.”
