Cape Town - New Zealand golf star Lydia Ko still has a few tricks up her sleeve as she tries to rekindle her game - just ask tennis superstar Maria Sharapova.
According to the Stuff website, Sharapova, 29, waiting to re-enter the game following her drugs ban, issued the "water bottle challenge" to Ko, challenging her to land a full bottle of water upright on one of her clubs.
Ko, 19, took up the challenge and safely delivered the bottle to the comparatively small face of one of her wedges.
Sharapova had similarly pulled off the stunt using one of her tennis racquets.
Ko has passed the challenge on to another tennis player, Switzerland's Stan Wawrinka.
