Danielle Collins produced a fairytale ending to her first WTA 1000 final in her last year on tour by beating Elena Rybakina to win the Miami Open.

The 30-year-old, who grew up in St Petersburg near Tampa, delighted the partisan home crowd as she produced a determined display to see off world number four Rybakina 7-5 6-3, before breaking down in tears.
