Wimbledon 2015: Novak Djokovic beats Jarkko Nieminen

The top seed won 6-4 6-2 6-3 to set up a third-round match with Australian 27th seed Bernard Tomic.

French Open champion Stan Wawrinka easily went past Victor Estrella Burgos 6-4 6-4 7-5.

Seventh seed Milos Raonic, US Open Champion Marin Cilic and 11th seed Grigor Dimitrov also progressed.

Canadian Raonic recorded the third-fastest serve in Wimbledon history as he beat Tommy Haas to set up a third-round match against Nick Kyrgios, who defeated Juan Monaco of Argentina 7-6 (7-5) 6-3 6-4.

It is a year to the day that Australian Kyrgios, 20, caused a major upset by defeating Rafael Nadal in the fourth round at Wimbledon.

Cilic came through a five-set thriller against Ricardas Berankis, while Dimitrov overcame America's Steve Johnson.

Djokovic, who took just one hour and 31 minutes to win his match, told BBC Sport: "On this warm day it's good to spend a little bit less time out there.

"I'm glad with the way I'm playing and I'm getting into form. As the tournament progresses, hopefully I'll be able to elevate the level of my performances."

The match was a farewell to Wimbledon for Nieminen, who is retiring at the end of the season at the age of 33.

"I congratulated him for a terrific career," said Djokovic.

"He is a very nice guy, one of the nicest and a fighter on the court. It was a pleasure to be the last one to play him at Wimbledon."

Raonic made quite a bang on his way to a 6-0 6-2 6-7 (5-7) 7-6 (7-4) win over Haas.

The 24-year-old Canadian sent down a 145mph serve against 37-year-old Haas on Court One, but it failed to eclipse Taylor Dent's 148mph offering from 2010 and fellow American Andy Roddick's 146mph from 2004.

Raonic, a semi-finalist in 2014, had three match points at 6-5 in the final set on the Haas serve, but the German battled back, only to lose it on the tie-break.
