Add it all up, and del Potro spent nearly 7 hours on court in a span of barely 25 hours. Williams' singles match was touch-and-go for more than an hour. Because of injuries, del Potro went 2 years without participating in a major until Wimbledon, so one big question is what his fitness level is. In her previous tournament, Wimbledon, Williams broke a racket after losing the opening set of a second-rounder against American Christina McHale. In a tournament that began without half of the ATP's top 10, del Potro looks like someone who might be able to add another medal to his 2012 bronze.
