Novak Djokovic's undefeated record at the Indian Wells Masters came to an end on March 16 as Australian Nick Kyrgios sent him crashing out of the Singles with a 6-4, 7-6 victory.
The world number two's disappointing year continues following on from lacklustre campaigns at the Australian Open in January, when he was eliminated in the second round by Denis Istomin, and the Mexican Open in February, losing to Kyrgios in the quarter-finals.
While Djokovic is still competing in the doubles alongside his partner Viktor Triocki, this is the first time the Serbian has been beaten in this tournament in three years, ensuring a new successor to the Indian Wells crown.

This also marks the second time Djokovic has lost to the 21-year-old Kyrgios, and the Australian continues to show impressive form on the back of reaching the semi-finals at the Mexican Open.
In the Californian sun, Kyrgios made the court his territory.

Having won 86% of his serves over the course of the tournament, he scored 14 aces over his opponent in a beautiful display of skill.
Pressuring the veteran into mistakes and capitalising on his opportunities, he took an early lead in the opening set, eventually securing it 6-4.
After losing the first set, Djokovic played a more even game on the second, even taking the lead at one point, and going to a tiebreak at the end, when he eventually lost the match and was knocked out of the tournament.
However, it was the Serb's reaction to a Kyrgios ace that has been caught on camera by a lucky spectator.
Djokovic let his anger show following the ace, and he smashed his racket on the court, not once, but twice.

Kyrgios' victory over Djokovic was his second over the 'Big 5', which include Djokovic, Andy Murray, Rafael Nadal, Stan Wawrinka, and his opponent in the quarter-finals, Roger Federer.
Having defeated Federer in the Madrid Masters in 2015, Kyrgios' mindset was as focused as ever after defeating Djokovic.
He said: "I'm just in a good space mentally. I'm really happy, I'm trying really hard for every point and obviously, I'm serving at a really high level."
After his loss, Djokovic was disappointed to lose, but was content with his previous success at the Indian Wells Masters.
"I am very proud of it. It had to end at some stage. Unfortunately, it was today."
Djokovic will be hoping his efforts in the doubles will make up for his underwhelming year, and Kyrgios will be hoping to repeat history against his Federer in the quarter-final match.
