Will any of the ATP's elite capture the 'Agassi Slam'?

When Novak Djokovic won the French Open this year, he became the third active men’s singles player to complete a career Grand Slam. However, his first-round flame out at the Olympics left him short on achieving the rarest feat in tennis: the “Agassi Slam," which Andre Agassi accomplished with this US Open title in 1999.

Agassi is the only men’s singles player in the history of the game to record a career Grand Slam, win Olympic gold, take home a year-end championship, and be part of a victorious Davis Cup team. (In doubles, Bob and Mike Bryan have accomplished the feat, while Daniel Nestor is only missing a Davis Cup title.)

Djokovic and his multiple major-winning contemporaries Andy Murray, Roger Federer, Rafael Nadal and Stan Wawrinka face various hurdles in pulling off the Agassi Slam, from the timeliness of the Olympic Games to surfaces that might not suit their playing styles.

Here’s a look at where those five currently stand in their pursuit, along with scenes from some of their title-winning performances. Also, in honor of Agassi’s Las Vegas roots, a game of chance, with a look at what factors might lead to wins or never-wills.

What He’s Won: Wimbledon (2), Olympics (2), US Open (1), Davis Cup (1), ATP World Tour Finals (1)

What He’s Missing: Australian Open (finalist, '10, ’11, ’13, ’15, ’16), French Open (finalist, ’16)

The Chances: While overall, Djokovic might be considered the most dominant player of the past three seasons, Murray should be looked as the one who’s made the most improvement. The Australian Open really holds no mystery for him, and his French Open final reflects a growing comfort on the clay. He could pull of the Agassi Slam within the first half of 2017.

Murray capped off a career-best season in 2016 with his first ATP Finals title:

What He’s Won: Australian Open (5), French Open (1), Wimbledon (3), US Open (3), Davis Cup (1), ATP World Tour Finals (5)

What He’s Missing: Olympics (bronze, '08)

The Chances: Even though he suffered a surprise loss at Wimbledon in 2016, which derailed his prospects at a calendar-year Grand Slam, Djokovic was still considered the favorite to win gold in Rio. However, facing Juan Martin del Potro in the very first round was too difficult a mountain to scale. Provided he stays healthy and motivated—and starts thinking of playing shorter points in the next year or two—Djokovic could still be in the medal mix by the next Olympics in 2020, even at the ripe old age of 33.

Djokovic’s pursuit of the French Open finally ended with victory this year:

What He’s Won: Australian Open (4), French Open (1), Wimbledon (7), US Open (5), Davis Cup (1), ATP World Tour Finals (6)

What He’s Missing: Olympics (silver, '12)

The Chances: Throughout his career, Federer has done things in tennis that have never been seen before. But can he pull off the near-impossible and win what can be considered a major event in Tokyo right before his 39th birthday? It’s unlikely. It’s not as though he’s short on gold: He and Wawrinka took home the doubles title in Beijing in 2008.

Federer clinched Switzerland’s first-ever Davis Cup title in 2014:

What He’s Won: Australian Open (2), French Open (9), Wimbledon (2), Olympics (1), Davis Cup (4), US Open (2)

What He’s Missing: ATP World Tour Finals (finalist, ’10, ’13)

The Chances: In two of the past three years, Nadal has had to cut his season short due to injury, which has led to him missing the ATP World Tour Finals. The 30-year-old Spaniard has struggled with a variety of ailments over the years and will be heading into 2017 on the comeback trail. The jury’s out on where his game will be, but if he can return to at least his 2013 form—and stay healthy—he can be a threat at at the ATP World Tour Finals for the next couple of years.

Nadal came out on top in the 2008 Wimbledon final in what is considered one of the best matches of all time:

What He’s Won: Australian Open (1), French Open (1), US Open (1), Davis Cup (1)

What He’s Missing: Wimbledon (quarterfinals, '14, ’15), Olympics (second round, ’08), ATP World Tour Finals (semifinals, ’13, ’14, ’15)

The Chances: In his Grand Slam finals, Wawrinka was never the favorite to win. In fact, until his Top 10 breakthrough in 2013, it appeared he would never live up to his talent and win a major. At 31, he has a short window to win Wimbledon and the ATP World Finals, but with his aggressive game, he could have a shot. By the time the next Olympics roll around in 2020, he’ll be 35, with that fact alone making him a long shot. He’ll always know what it feels like to stand atop the medal-winners podium, though, after his doubles gold-medal win with Federer.

Wawrinka emerged from Federer’s shadow with his first Grand Slam at the Australian Open in 2014:
