Nadal overcomes Kyrgios to reach the Wimbledon third round

Rafael Nadal allowed the tennis to do the talking against an irate Nick Kyrgios, who twice served underarm, to progress to the Wimbledon third round.

Australian Kyrgios spent much of the match audibly questioning Nadal's speed of play as the world number two prevailed 6-3 3-6 7-6 (7-5) 7-6 (7-3).

His constant arguing saw him handed an official warning by the chair umpire, who he later called a "disgrace".

Nadal will play Frenchman Jo-Wilfried Tsonga in the next round. Victory was two-time Wimbledon champion Nadal's 50th match win at the All England Club.

It started at a canter for 18-time Grand Slam champion Nadal, holding to love in the opening game before immediately breaking Kyrgios who had already failed to pull off a "hot dog" lob between his legs.

Barely 15 minutes had been played when Kyrgios started to show signs of discontent, telling the chair umpire he had been ignored after requesting a challenge.

He then started to complain about Nadal's speed of play, indicating the Spaniard was not ready when he was preparing to serve.

And he then sealed his third game with an underarm serve, an action which had previously led to Nadal accusing him of lacking respect.

As Nadal took a comfort break at the end of the first set, Kyrgios making his feelings known with an almost constant shaking of the head.

He was the first to go a break up in the second set, firing a stunning forehand winner down the line on break point, before then saving two break points, the first with a deft drop shot, to go 3-0 ahead.

He pulled out another underarm serve, this time read by Nadal, but unlike the first, it was met by boos from the crowd as he extended his lead at 4-1.

Kyrgios - who frequently spat on the hallowed Centre Court turf - was then broken to love by Nadal, after which he engaged in a rant at the chair umpire which ended in him being handed an official warning.

That argument continued into the third set, with Kyrgios telling the chair umpire he had "no idea" as Nadal passed the time juggling the ball from foot to foot.

At 4-4, Kyrgios unleashed a forehand directly at his opponent's body, leaving a rattled Nadal glaring at his opponent and, when he sealed that game, Nadal let out all his pent-up fury.

He went on to take the set on a tie-break, leaping into the air and releasing a barrage of Spanish, no doubt some colourful wording among it.

The fourth set went with the serve with Kyrgios uncharacteristically quiet, before Nadal dominated the tie-break to seal his spot in the third round.

Perhaps surprisingly, the two were amicable at the net as another chapter in their joint story came to an end.
