NEW YORK (Reuters) - Australian Bernard Tomic courted controversy yet again when he fired lewd comments toward a heckler at the U.S. Open during his first-round upset loss to Bosnia's Damir Dzumhur on Tuesday.

Television cameras and microphones caught Tomic directing a number of sexually explicit comments toward someone in the crowd during the first set of his 6-4 6-3 4-6 7-6(0) defeat to world number 72 Dzumhur.
