Serena Williams was in tears as she retired early in the Rogers Cup final due to an upper back injury, handing unseeded teenager Bianca Andreescu the title in her homeland.

Williams, attempting to claim her first WTA Tour title since returning from maternity leave, was a break down at 3-1 in the first set in Toronto on Sunday when she declared she was unable to continue.

The 23-time grand slam singles champion sobbed as she was embraced by the 19-year-old Andreescu, after succumbing to an injury setback just a fortnight before the US Open gets under way.
