Juan Martin Del Potro wasn't happy with losing a first-set tiebreaker, the impending darkness, Wimbledon's slippery grass courts or the shoes which couldn't keep him upright on those grass courts. So after losing the opening set of Wednesday's second-round match against Olivier Rochus, Del Potro, sensing that the match would be delayed until Thursday because of nightfall, took off his shoes while walking to his chair.
Seconds later, when officials ultimately announced the decision to postpone the match, the 2009 U.S. Open champion took those shoes and launched each into the crowd. The first flew out of the stadium and landed on a nearby concourse. The other was retrieved by a fan high in the stands.
