Watch: Pregnant Serena Williams still packing a punch

Serena Williams shows no sign of putting her feet up just a couple of months before she is due to give birth as the legendary American gears up for a comeback.

The 23-time Grand Slam singles champion is expecting her first child in August or September, but her coach, Patrick Mouratoglou, revealed during the French Open that she has already been discussing when she can return to top-level tennis.

Williams posted a video Thursday night on Instagram of herself practicing despite being heavily pregnant.

The bad news for the 35-year-old’s rivals is that she clearly has not lost her desire to add to her Open Era record haul of titles and looks eager to make up for lost time.
