Petra Kvitova said she has been encouraged by the success of several new mothers in their return to the WTA Tour, but she is tempering expectations ahead of her own comeback from maternity leave this week.

She has won 31 titles, made history at Wimbledon and earned more than $37 million. Now, Petra Kvitova returns to the tour not to prove anything, but because she still loves the game.

Two-time Wimbledon champion Petra Kvitova loses to Britain's Jodie Burrage on her return from maternity leave at the ATX Open.
