PHOTOS: Venus, Serena Williams try their hand at cricket

World No 1 Serena Williams and her sister Venus tried their hand at cricket with the Melbourne Renegades players on a hotel roof top on Thursday.

Serena Williams played cricket left-handed and showed off the athletic prowess while Venus tried her hand at wicket keeping.

Joined by her older sister Venus, 33, the siblings had a ball alongside members of the Melbourne Renegades cricket team, Muthiah Muralidaran and Aaron Finch.

Sharing a couple of rooftop photos of the two, Serena tweeted, "Sista's we're two of a kind...." and "So sista I'm keeping my eye on you..."

Sri Lanka spin bowling legend Muttiah Muralitharan met the tennis stars during the media event for the upcoming Australian Open tennis tournament in Melbourne. Muralitharan is currently in Australia playing for the Melbourne Renegades in the Big Bash League.

Serena Williams is gunning to match former World No 1 Chris Evert and Martina Navratilova by winning an 18th Grand Slam title at the upcoming Australian Open.

The American ace cemented her dominance of the sport with 11 titles last year, including the US and French Opens, and picked up where she left off by winning the Brisbane International on Saturday.

Williams, who will be entering the season-opening Grand Slam as red-hot favourite, however, said that she feels she still has room for improvement if she wants to win the Open.

The tennis stars were not dressed in typical sportswear attire.

They opted to show off their casual chic style, with Serena flaunting her curves in a denim overall playsuit and teamed it with black sneakers.

Meanwhile, Venus kept looked in a printed sundress and a pair of flats.
