Djokovic sweeps Murray

Novak Djokovic benefited from an erroneous call and claimed he didn’t realize he had broken the rules.

When Andy Murray walked to the net and challenged him about it, Djokovic responded with a shrug and a sheepish smile.

Murray argued and TV replays confirmed he should have be awarded the point because Djokovic’s racket was on the far side of the net when he hit the ball.

A flustered Murray committed unforced backhand errors on the next three points to lose the game and the set.

Murray took a lead in the second set but lost the final four games and the last 12 points.

Djokovic’s next opponent, Nishikori, will be playing in only his second ATP Masters 1000 semifinal, and his first in 2 years.

Li’s opponent Thursday night will be Dominika Cibulkova, who erased three match points in the second set one when a call was overturned via replay and beat Agnieszka Radwanska 3-6, 7-6 (5), 6-3.

Murray won the Key Biscayne title in 2009 and 2013 but wasn’t at his best against Djokovic.

Djokovic had won praise for his sportsmanship when he conceded a point following an erroneous call in his match Tuesday, but against good friend Murray, he left the verdict to the umpire.

Any hard feelings on Murray’s part didn’t carry over after the match, when he shook hands with Djokovic and Steiner.
