THE BIG 2
Nadal and Djokovic are separating themselves from the other two members of the Big 4, Federer and Andy Murray. Federer, 32, has lost before the quarterfinals at three of the last four majors. Murray made the French Open semifinals, but was overwhelmed by Nadal 6-3, 6-2, 6-1. Setting his sights on a title defense at Wimbledon starting June 23, Murray made a groundbreaking choice for his new coach, hiring former women's No. 1 Amelie Mauresmo.
