DUBAI, Feb 23 ― Iga Swiatek is one step closer to claiming a rare Doha-Dubai double thanks to a convincing 6-3, 6-2 quarter-final victory over Chinese sixth seed Zheng Qinwen yesterday in the UAE.

The world number one, who lifted the trophy in Doha for a third consecutive time last Saturday, extended her unbeaten streak to seven matches and is looking to become the first woman since 2007, and just the third overall, to win both Gulf tournaments in the same season.
