Carreno Busta books spot in fourth round

Pablo Carreno Busta marches into the fourth round at the Australian Open for the first time - and for the third straight Grand Slam he has contested - with a 7-6(4) 4-6 7-5 7-5 win over Gilles Muller. 

Muller whizzed 74 winners past Carreno Busta, but the Spaniard set up his trenches behind the baseline and inflicted death by a thousand forehand and backhands. He made just 22 unforced errors - only FOUR off the forehand wing! - in three hours and 18 minutes of tennis. He will face the winner of Ryan Harrison and Marin Cilic for a spot in the quarterfinal.
