Short as it was, Roger Federer’s shift lasted longer than that of Novak Djokovic.

The three-time champion was through in 40 minutes when his opponent, Martin Klizan, retired on account of a calf injury. Given his erratic results, and two new coaches (Andre Agassi and Mario Ancic) Djokovic likely wanted a longer workout.
