The draws for Wimbledon 2015 have been announced, setting up potential matchups among tennis’ “Big Four” as early as the quarterfinals. Novak Djokovic is the favorite to win the title, but Roger Federer, Andy Murray and Rafael Nadal also have a good chance to win the third Grand Slam of the year.

The tournament begins on Monday, June 29, and is set to conclude on July 12. Below is a look at the opening round schedule and draw for each member of the “Big Four.”

Novak Djokovic

The defending champ will open the tournament with a match against No.33 Philipp Kohlschreiber of Germany. Kohlschreiber recently lost his first match at the Gerry Weber Open, losing to eventual champion Federer. Kohlschreiber doesn’t have a win this year, with his best showing coming in Munich two months ago when he lost to Andy Murray in the finals.

Djokovic will face Jarkko Nieminem or Lleyton Hewitt in the second round, and he’s eyeing a possible quarterfinals match with Marin Cilic, who reached the quarterfinals at Wimbledon last year. If Djokovic has a rematch from the French Open finals against Stan Wawrinka, it won’t happen until the semifinals. He can’t face a member of the “Big Four” until the finals.

Roger Federer

The seven-time Wimbledon champ is set to face No.87 Damir Dzumhur in the first round. The 23-year-old from Bosnia faced Federer in his first match at Roland Garros, losing in straight sets in the round of 32. Dzumhur hasn’t won any tournaments this year, picking up his most impressive win against No.50 Marcel Granollers in Casablanca in a tournament that saw him advance to the semifinals.

Before Federer reaches the quarterfinals, matches with Sam Querrey, Igor Sijsling, Jack Sock and Sam Groth are a possibility. Gael Monfils and Gilles Simon are potential quarterfinal opponents for Federer, and he seems destined to meet Andy Murray in the semifinals, possibly for the right to face the world’s No.1 player.

Andy Murray

A match with No.58 Mikhail Kukushkin awaits Murray when he begins his quest towards a second career Wimbledon championship. Kukushkin hasn’t had much success in 2015, failing to win more than one match in any tournament since the Australian Open. His best win since the year’s first Grand Slam came against Steve Johnson, who ranked No.43 at the time of their match.

Before he can meet Federer in the semifinals, Murray could face a few formidable opponents. A match with Nadal might await him in the quarterfinals. If the King of Clay is bounced early, David Ferrer could stand in Murray’s way of reaching the semifinals.

Rafael Nadal

As the No.10 seed in the tournament, Nadal will take on No.41 Thomaz Bellucci in his Wimbledon opener. Bellucci hasn’t played since the French Open, where he lost to Kei Nishikori in his second match. Prior to the French Open, Bellucci won the Geneva Open title, beating then-No.50 Joao Sousa in the finals.

If Nadal hopes to win the championship, he might have to go thought all members of the “Big Four.” A quarterfinal match with Murray, a meeting with Federer in the semifinals and another match with Djokovic could await Nadal.
