Djokovic given tough examination

Novak Djokovic felt his second-round, straight-sets victory over Ryan Harrison was far tougher than the score line suggested.

The defending champion's match against the rising US star was the last contest on Centre Court on Wednesday and, due to the wet weather, was played with the roof closed.
And it took until just before 10pm for the world number one to complete the job, as he triumphed 6-4 6-4 6-4 to set up a third-round clash with either Czech Radek Stepanek or Germany's Benjamin Becker.
The Serb was not at his best during the contest but managed to keep ahead of the American starlet despite having to stave off break points in the second set.
He was 0-40 down and trailing 2-3 and, had the Texas resident converted, the match might have gone to four sets.
But it was not to be and Djokovic felt that the margin of victory was far closer than it appeared.
"It was a straight-sets win, but it was much more difficult than the scoreboard suggests," he told BBC Sport. "I was in trouble in the second set. It was difficult to adjust your movement under the roof; Ryan was serving fantastic and it made for a great match.
"It was a close match because he performed really well when he needed to but I got the crucial breaks when I needed to."
