NEW YORK (Reuters) - Australian Bernard Tomic admitted he is "not the smartest person in the world" after exiting the U.S. Open in the first round on Monday with a 3-6 6-3 6-4 6-4 defeat to Gilles Muller that could send him tumbling out of the top 150.
Tomic was returning to tournament play for the first time since his first round loss at Wimbledon in July, after which he said he was bored with tennis and had played at 50 percent for much of his career.
