Wimbledon, England: Wimbledon is only one tournament, but in many minds it is the biggest, grandest stage in tennis. So let the speculation begin that cracks in the wall of dominance enjoyed by the group known as the Big Four of the men's game may have finally appeared during Wimbledon's second week.
On successive days on Centre Court, former champions were dismissed by younger players without a Grand Slam title to their names. After the 19-year-old Australian Nick Kyrgios' four-set defeat of the two-time champion Rafael Nadal in the fourth round Tuesday, Grigor Dimitrov, a rising 23-year-old Bulgarian, thrashed Andy Murray, the defending champion, 6-1, 7-6 (4), 6-2, in the quarterfinals Wednesday.
Kyrgios' remarkable run ended when he collided with the huge game of the 6-foot-5 Canadian Milos Raonic, who at 23 is also trying to break through the wall. Admittedly tired after his upset of Nadal, Kyrgios watched 39 aces sail by him during Raonic's 6-7 (4), 6-2, 6-4, 7-6 (4) victory.
