(Reuters) -Iga Swiatek showed why she is world number one and the hot favorite to win this year's WTA Finals in Forth Worth with a 6-2 6-3 dismantling of Daria Kasatkina before Caroline Garcia beat Coco Gauff in straight sets on Tuesday.

The match felt all but over for Kasatkina when Swiatek saved two break points and pounded a forehand winner past the Russian's outstretched racket for a 3-0 first-set lead.
