(Reuters) - Gael Monfils was accused by commentators of 'tanking' during his first-round match at the Western and Southern Open in Cincinnati on Monday, with the 14th-seeded Frenchman losing to Poland's Jerry Janowicz 6-4 7-5 in 75 minutes.
Monfils served so quickly in the second set the ball boys barely had time to get into position after each point before the ball was back in play.
Television commentators said at one stage they thought Monfils was in a hurry because he had a tee time booked to play golf.
During one rally he turned his back on his opponent briefly, prompting disbelief in the commentary box.
