The 2022 Australian Open runner-up Collins defeated Russian Daria Kasatkina 6-2 6-1 for her 13th straight match victory on Sunday, becoming the first player since Serena Williams 11 years ago to win Miami and Charleston in consecutive weeks.
"Thank you for allowing me to live out my dream," Collins told the crowd at the trophy ceremony.
Collins, a 30-year-old who has said this season will be her last on the WTA Tour because she's suffering from endometriosis, has made it a memorable one.Â
She led 3-0 in the opening set, breaking the 2017 Charleston champion Kasatkina's serve twice as the crowd cheered the American's every move.
Collins didn't let up in the second set, taking a 5-0 lead before the Russian held serve.
Collins closed the match with a volley at the net, pumping her fist as her face broke into a smile.
Collins, the world No.22, has won 26 of her past 27 sets. The only one she dropped on the green clay came on Wednesday against 2023 Charleston champion Ons Jabeur.
Kasatkina, the world No.11, played with a heavy wrap on her right thigh and struggled with her serve throughout, regularly putting herself behind.
