Serena still hitting balls, baby bump and all

At six months pregnant, Serena Williams is refusing to let her baby bump get in the way of forehands or backhands - she is still working out and playing tennis to retain her touch, her long-time coach told Reuters on Saturday.

Although the 23-time Grand Slam champion has not played competitively since winning the Australian Open in January, she has been soaking up the Roland Garros atmosphere this week, watching sister Venus play and catching up with friends.

"She's working out and she even played tennis the other day," her long-time coach Patrick Mouratoglou said in an interview in Paris on Saturday.
