Muguruza retains Monterrey Open title as Azarenka retires

Spanish tennis player Garbine Muguruza retained the title at the Monterrey Open after former world number one Victoria Azarenka retired in the final when the scoreline read 6-1, 3-1, in Muguruza's favour. "It's unfortunate I couldn't give my best today," said a tearful Azarenka, who had not previously reached a final since her first child's birth in December 2016.
