There are no excuses now. He's 21 years old. Nadal and Djokovic won Slams at 19-20 years of age. Del Potro won the USO at 20. Which means Raonic is expected to start making runs at the Slams immediately! His game is good enough. His serve is incredible. Big forehand. Good touch. Is he ready to beat a top 3 player and win any of the AO, Wimbledon or USO this year?
