Elise Mertens claimed the biggest win of her career on Saturday , surprisingly coming from a set down to beat world number three Simona Halep and clinch the Qatar Open.
The world number 21 won 3-6, 6-4, 6-3, despite being outclassed in the first set, overcoming an eight-minute medical timeout for back pain in the second set, and losing 18 consecutive points at one stage in the match.
Her win, in a little over two hours, was her third victory over a top ten player in Doha this week, and her second over a Grand Slam champion.
Mertens started nervously, lost her opening service game, and the first set in just 32 minutes.
I was really tired in the third set, I couldnt have the chance to win this match, said Halep, who won the Qatar title in 2014.
