Kim Clijsters crashed out of the Chicago Fall Tennis Classic in the opening round on Monday after losing 6-3, 5-7, 6-3 to Taiwan’s Hsieh Su-wei.

Clijsters, who was playing in her first match of 2021, is making another comeback after retiring in 2012. She has yet to win a match since rejoining the Tour last year.

“I came close today, but I still have a good feeling,” she said.

I’ve made progression, and I think that’s the most important thing. What I’m looking at is that I’m improving overall, and that’s the positive thing.”
