The traditional pre-cursor to Wimbledon, the biggest names in tennis have been getting the grass court season underway at Queen's Club in London every June since 1890.
This year, the Aegon Championships features one of its strongest lineups ever, with stars including Andy Murray, Stan Wawrinka and Milos Raonic going head-to-head for $1m in prize money.
The list of previous winners who have triumphed on what is considered to be one of the finest grass court in the world reads like a who's who of men's tennis - Murray, Connors, Nadal, McEnroe, Sampras - while the tournament itself is now one of the most anticipated on the ATP World Tour 500.
Last year's event was won by Andy Murray, his fourth triumph in seven years. Can anyone stop him this time?
What started as a challenge between Great Britain and the United States in 1900 has grown to become the world cup of tennis, with 550 players from 135 nations set to compete in 80 ties held in 60 countries this year.
Founding members Great Britain are the Davis Cup by BNP Paribas holders, with Andy Murray and co. ending a 79-year wait for success with victory over Belgium in front of 39,000 fans in 2015 - the first time Great Britain had lifted the cup since Fred Perry's team in 1936.
The GB team continues its defence in 2016 with a quarterfinal against Serbia on 15 - 17 of July. But if you can't wait until then, get your fix of action at the Davis Cup Trophy Tour, on its way around 100 venues across the UK before the end of the year.
It might have been launched back in 1963 to celebrate the 50th Anniversary of the International Tennis Federation, but don't be fooled: the Fed Cup by BNP Paribas is no party. As the world's largest women's team sport event, it's a tournament everyone wants to win.
This year, teams of players from 99 countries entered, with the Czech Republic now favourites to retain their title when they take on France in the final this November.
Aiming for their fifth title in six years, the Czechs will become the most successful team this century if they overcome France, who have not tasted success since 2003.
For Great Britain, all eyes are on the 2017 competition and winning promotion to the competition's top tier. Johanna Konta and the rest of the team suffered the disappointment of defeat to Belgium in the promotion play-off back in February.
Tennis was initially played with hands instead of rackets, and was called 'jeu de paume' - meaning game of the palm. It wasn't until the 16th century that rackets were introduced.
