AFP, Abu Dhabi :
A slow moving Serena Williams made an encouraging return to tennis after maternity leave, taking a set off the French Open champion Jelena Ostapenko in an exhibition match Saturday, but said she has not made up her mind about defending the Australian Open title.
In a match featuring a super tie-break and lasting one hour and seven minutes, Ostapenko won 6-2, 3-6, 10-5.
The 36-year-old American, winner of 23 grand slam single titles, was making a comeback after taking nearly 11 months off to have her first child.
Her last match was the Australian Open final, which she won despite being two-month pregnant.
