2) Milos Raonic ousted by a qualifier
Fifth seed Milos Raonic was another high profile casualty in the first week of the US Open. The big-serving Canadian had just become the first player from his country to reach a Grand Slam final when he defeated Roger Federer in the Wimbledon semifinals.
Though he lost the final to Andy Murray, Raonic had announced himself to the world as a force to be reckoned with at Grand Slams. As such his disappointing 6-7, 7-5, 7-5, 6-1 loss to American qualifier Ryan Harrison in the second round came as a big shock.
He was hampered by cramps in his serving arm but that does not take the gloss of a brilliant victory for Harrison. Raonic also admitted that he suffered a bout of nerves – “It was probably just nerves and stress, a mental sort of over-exuberance.” Whatever the reason, it was a huge upset.
