Novak Djokovic, Rafael Nadal and the "5-Tool Guys" of Men's Tennis

In pro sports, there are just some guys who can do it all physically.

Baseball players who excel in hitting for average and power, fielding, throwing and running the bases are often referred to as "5-tool guys"—and can often carry a team to success.

While tennis players have to call upon a tremendous amount of mental fortitude, it doesn't hurt to have a great serve, excellent return, equally strong forehand and backhand, superior footwork and great hands at the net—or "five tools"—to carry them through the ebbs and flows of a match.

Here are 10 players on the ATP Tour who have all the tools necessary to get the job done.

Novak Djokovic

World No. 1 Djokovic has been dominant this year, with a 54-2 record and nine tournaments won so far.

He's not going to blast you off the court with aces, but he's among the ATP Tour's leaders in service games won. He's also winning nearly 40 percent of his opponent's service games.

Djokovic is rarely out of position on the court, which enables him to blast groundstroke winners off both sides. And while playing on grass courts has changed, it's still nice to be able to volley effectively, which the 2011 Wimbledon champ will attest to.

Rafael Nadal

Probably the best word to describe Rafa's groundies is "ridiculous." The amount of spin he places on the ball has handcuffed more than a few players in his career.

Nadal's serve has become more of a weapon the past few years, which has helped carry him to Major titles on faster services. Getting a serve or a ball past him in a baseline rally is nearly impossible, and it's not that easy a task while he's at the net either, as indicated by his seven career doubles titles.

Roger Federer

Sure, he's not winning everything under the sun right now, but you can't argue at all what arguably the greatest tennis player of all time can do on the court.

Federer can hit his groundstrokes with power or spin, display the same capabilities with his serve and volleys, scramble with the best of them, etc.

Actually, you could probably call him a "10-tool guy."

Andy Murray

Only two players have made the semis at all three Grand Slams so far this year: Djokovic being one, and Andy Murray the other—a testament to versatility.

At the onset of his career, Murray was probably more content out-rallying players, but realized that would only take him so far. Adding more pop to his game has helped Murray hold his serve more often—he's already one of the best returners on tour.

And getting a ball past Murray might be near-Nadal-impossible levels.

Mardy Fish

It used to be you could sum up Mardy Fish's game in four words: "Big serve, big backhand."

That couldn't be further from the truth now, as he's practically reinvented himself to become a Top 10 player. Aside from the serve and backhand, Fish's once-weak forehand is now a weapon, he's one of the best movers out there and he's winning the right amount of return games.

Fish's renaissance should be a lesson to a lot of players out there that building up other tools can help one hit new highs.

Gilles Simon

While the Frenchman isn't exactly the most imposing player out there, he has cracked the Top 10 in the past and is currently on the verge of getting there again.

Simon is steady in all physical facets of the game and knows how to use his tools to manage points effectively.

Gael Monfils

Probably one of the most physically-gifted players out there, Gael Monfils can do it all: serve big, get a lot of returns in play, get to any and every ball hit on the court, hit groundstroke winners from anywhere on the court and utilize super-soft hands at the net.

However, putting all of that together and using his abilities at the right time are the big questions with Monfils. If he ever does figure it all out, he can be a consistent Top Three player.

Radek Stepanek

The champ in Washington a few weeks ago is a rare breed on the ATP—a player who's just as comfortable at the net as he is at the baseline. Hitting his spots with his serve helps Stepanek, and he knows how to get first and second serve returns back deep.

Being one of the older players out there doesn't stop Radek Stepanek in getting to a lot of balls. To do what he's doing on the other side of 30 is remarkable—and that includes his celebratory "worm" dance after big match wins!

Michael Llodra

The third Frenchman on this list is capable of doing it all, and he's currently the only player on the ATP Tour ranked in the Top 10 in doubles and Top 30 in singles.

Llodra's volleying is top-notch, and he's the more steady returner in his pairing with Nenad Zimonjic.

Jurgen Melzer

Austria's top player is also one of the game's most unpredictable; you don't know if he's going to blast a winner from the back of the court or hit an approach off a drop shot.

If you get to his drop shot, Jurgen Melzer will be there to knock off the volley. He's been racking up wins against the elite on all surfaces with some of the best all-around tools in the game.
