Kim Clijsters won a dramatic semi-final battle of the Belgians against Justin Henin to reach the final of the Sony Ericsson Open on Thursday. The 6-2 6-7 7-6 victory means Clijsters will play for a 37th career title on Saturday against Venus Williams, who earlier cruised to a 6-3 6-4 win over France's Marion Bartoli. Clijsters dominated the opening set of her encounter with Henin but then, having been 3-0 up in the second, lost out in a tiebreak to allow the game into a decisive third set. Neither of the two former world number ones, who have both made comebacks to the game, dominated on serve and Clijsters produced a double fault when serving for the match.
