Big Four Back Together: The Big Four of Andy Murray, Novak Djokovic, Rafael Nadal and Roger Federer have accounted for 42 of the past 47 Grand Slam tournaments since Roland Garros in 2005 when Nadal won his first of 14 Grand Slam titles. During the current stretch, Nadal has won 14 titles, Federer 13, Djokovic 12 and Murray 3.

The three other players to win a Grand Slam title during the span are Stan Wawrinka, a three-time champion (2014 Australian Open, 2015 Roland Garros, 2016 US Open), Marin Cilic (2014 US Open) and Juan Martin del Potro (2009 US Open).

The Big Four have won past 11 of the past 13 titles in Melbourne since Federer won his first title in 2004. Djokovic leads the way with six titles followed by Federer (four) and Nadal (one). The trio, along with Wawrinka, are the former Australian Open champions in the draw.

Last season, the Big Four played in only three tournaments together. Here is a look at their results:

Murray Eyes First Title: World No. 1 Andy Murray is the top seed in a Grand Slam tournament for the first time in his career. Murray is the first British man to hold the top seed in a Slam since Bunny Austin at the 1939 Wimbledon.

Murray is making his 12^th straight appearance in Melbourne and he’s hoping to duplicate the feat of two of his rivals. Last season Djokovic won his first Roland Garros crown and Wawrinka his first US Open title, both in their 12^th tournament appearance.

Murray is trying to capture his first title after reaching the final five times (2010-11, 2013, 2015-16). He is 0-5 vs. Djokovic in Melbourne with his last four runner-up results coming to the Serbian. Murray has reached the final in a career-best six consecutive tournaments going back to last season and his 28-match winning streak came to an end with his final loss to Djokovic in Doha on 7 January.

Novak Eyes Record: Two-time reigning champion (six overall) Novak Djokovic is trying to become the all-time leader with the most Australian Open singles titles. He is currently tied with Aussie great Roy Emerson with six titles. Djokovic is the No. 2 seed for the first time in a Grand Slam tournament since the 2014 Roland Garros.

Djokovic has won the title in five of the past six years (39-1 record) with his only loss coming to Wawrinka in the quarter-finals in 2014. Overall he has a 57-6 career record in Melbourne. The 29-year-old Serbian, who won titles in 2008, 2011-13, 2015-16, is one of three players to win at least three titles in a row at the Australian Open along with Aussies Jack Crawford (1931-33) and Emerson (1963-67). Djokovic opened the season by repeating his title in Doha (d. Murray).

Roger Returns: Federer is making his 18^th straight appearance at the Australian Open and he opens against qualifier Jurgen Melzer. The four-time Australian Open champion has an 80-13 match record. The Swiss superstar will be playing his first tour-level match since 8 July 2016 when he lost in five sets in the semi-finals to Milos Raonic at Wimbledon. He missed the rest of last season with a knee injury.

It is also Federer’s first appearance outside the Top 10 in Melbourne since 2002 when he was ranked No. 12 and his No. 17 seeding is his lowest in a Grand Slam since he came in unseeded at 2001 Roland Garros. Federer finished last season with a 21-7 match record and No. 16 ranking.

His streak of 14 consecutive years in the year-end Top 10 ended, which is second only to Jimmy Connors’ 16. Federer’s best result was a runner-up in Brisbane (l. to Raonic) in the opening week of the season.

His streak of 15 straight years with at least one ATP World Tour title also came to an end. Prior to Federer’s knee injury, he was still playing at a high level as indicated in the Infosys ATP Scores & Stats. He would have been in the Top 5 in the following categories if he had played enough matches to qualify:

First Serve Points Won      80%

Second Serve Points Won 56%

Service Games Won          90%

Career Double Slam: Nadal is trying to become the third player in men’s tennis history to win each Grand Slam singles title twice in his career. The 2009 Australian Open champ is a nine-time Roland Garros champion and two-time winner at Wimbledon and US Open.

Aussies Rod Laver and Roy Emerson are the other players to accomplish the feat. Laver won a calendar Grand Slam in 1962 and ’69 while Emerson earned six Melbourne titles and two each at Roland Garros, Wimbledon and US Open.

Nadal is the No. 9 seed, his lowest seed in a Grand Slam tournament since he was No. 10 at 2015 Wimbledon. It is Nadal’s lowest Australian Open seeding since he was unseeded in 2005. Nadal has a 45-10 record in Melbourne, reaching the quarter-finals or better in eight of the previous 11 visits. Last year he lost in the first round for the first time to countryman Fernando Verdasco in five sets.

Kyrgios, who won a career-best three ATP World Tour titles last season, is one of 11 Aussies in the main draw. No. 2 Aussie Bernard Tomic, who is seeded No. 27, is making his ninth straight appearance (15-8 record). His best result is the fourth round in 2012, 2015-16.
