Kim Clijsters beat Jelena Jankovic 6-2 6-3 at the WTA Championships in her first outing since winning the US Open at Flushing Meadows.
The Belgian got off to a successful start in the White Group, though she was not at her best in a match that failed to hit the heights in Doha.
Clijsters began well enough, breaking her opponent's serve in the very first game and then following that up with another soon after to go 5-2 ahead.
She comfortably served out for the opening set and although Jankovic did improve in the second, the out-of-sorts Serbian still slipped to a second defeat in the season-ending tournament.
"It was my first match back, and I was happy - not with everything but I'll take that," she said afterwards. "I need to be a little more consistent and deliver fewer double faults, but I will try to be better tomorrow (Thursday)."
Good to see Kim doing well, and back on court. Looking forward to the next match.
