World number one Justine Henin began the defense of her WTA Championships title with a 6-1, 7-6 win over Russian Anna Chakvetadze at the Madrid Arena in Madrid, on Tuesday.
The 25-year-old Belgian top seed rattled through the first set in 24 minutes but had to resist a determined fightback by her opponent before winning her opening round robin match in the yellow group of the $3 million end-of-season tournament.
