Andy Murray suffered another setback with a marathon loss to Czech teenager Jakub Mensik in the Qatar Open second round on Wednesday.

Former world number one Andy Murray ended a six-match losing run to topple qualifier Alexandre Muller 6-1, 7-6 (7/5) at the Qatar Open on Tuesday.

Swiatek is the first player to win three straight titles at the same WTA event since Serena Williams completed a Miami Open hat-trick from 2013-15.

Naomi Osaka said she had taken a leaf out of Novak Djokovic's tactical playbook and tweaked her return game at the Qatar Open after the former women's world number one earned back-to-back wins for the first time in almost two years.

The 27-year-old, who won in Rotterdam last Sunday, convincingly ended his 35-year-old opponent's comeback heroics that saw Murray fight four three-set battles and overcome eight match points to reach the final in Doha

It is Swiatek's first title of a year, and follows her shock fourth-round exit in the Australian Open at the hands of Wimbledon champion Elena Rybakina
