Considered a fair hope to go deep at the Open, 5th seed Milos Raonic, who had a decent start to his hard-court season this year, lost in five sets to Spain’s Pablo Carreno Busta, the #20 seed.

Raonic took an early lead, winning the first set 6-4, when Carreno Busta battled back to take the next in a tiebreak. The Spaniard played a sustained level of tennis thereafter, and although Raonic edged him out in the next set tiebreak, he took the final set and decider 6-4, 8-6 to set up an all-Spanish quarter-final against Rafael Nadal.
