VIDEO: Federer pulls out unfair drop shot

World No. 2 Roger Federer took a bit of time to get going against his second-round Australian Open opponent - 48th-ranked Simon Bolleli - dropping the first set 6-3. 

But Federer got his legs under him and stormed back to grab the second set. Early on in the third, he made sure to let Bolleli knew that the only victory he'd be taking away from the match would be a moral one. 

This drop shot was just plain cruel. 

Federer ultimately prevailed, 3-6, 6-3, 6-2, 6-2.
