ABU DHABI, United Arab Emirates - Andy Murray's 2013 season got off to a shaky start Thursday with a 6-3, 6-4 loss to Janko Tipsarevic in the opening match of the World Tennis Championship exhibition tournament.
Two early breaks in each set helped Tipsarevic dispatch the third-ranked Murray. The Serb next faces Nicolas Almagro, a late replacement for Rafael Nadal, who pulled out of the tournament with a stomach bug.
"It's not every day that you get to play a Grand Slam champion and an Olympic gold medalist," said Tipsarevic, who is ranked No. 9. "I know it's an early-season tournament, but I can tell you that the six of us take this very seriously."
