London - Milos Raonic eased into the Wimbledon second round with a 7-6 (7/4), 6-2, 6-4 victory over Pablo Carreno Busta in front of new coach and All England Club legend John McEnroe on Monday.
Canadian sixth seed Raonic hired three-time Wimbledon champion McEnroe earlier this month in a bid to hone his game for the grass-court Grand Slam.
The fast grass of Wimbledon suits 25-year-old Raonic's game, as he showed when he reached the Wimbledon semi-finals in 2014.
And, under McEnroe's tutelage, he had shown further progress on the surface at Queen's Club earlier this month, when he reached the final before narrowly losing to world number two Andy Murray.
With McEnroe watching on Court Two, Raonic stayed in the groove with a comfortable start to his Wimbledon campaign.
Raonic will play Italy's Andreas Seppi for a place in the last 32.
