Novak Djokovic defeated Jo-Wilfried Tsonga on Monday in the round of 16 at Wimbledon to advance to the quarterfinals, where he will face Marin Cilic.
All was well, because the challenge showed the ball was in and the point was good.
Djokovic won Wimbledon in 2011 and was runner-up to Andy Murray last year. 2011 was Djokovic's best year, when he won the Australian Open, Wimbledon, and the US Open. He has never won the French Open, but was runner-up this year and in 2012. He won his first Grand Slam at the Australian Open in 2008 and that remains the only one he has won more than once (four times total). It is also his most recent win, when he won it in 2013.
According to Wimbledon's twitter, Djokovic advancing to the quarterfinals marks his 21st consecutive Grand Slam quarterfinal appearance, which is the third longest streak "the 3rd longest streak in the Open Era after Federer (36) and Connors (27)."
