The PGA Tour has attracted many new fans to events because of the new young guns that are quickly taking over the sport.

Currently, there are 10 players in the top-30 of the world golf rankings that are under 30 years of age. They have won major championships and tournaments on different Tours in the United States and abroad.

Here is a list of the top 10 players under thirty who are shaping the next generation of champion golfers:

1. Rory McIlroy

Currently at No.2 on the world golf rankings, McIlroy has made quite a splash on the PGA Tour since turning pro in 2007 at the age of 18. Now at 23 years old, the young phenom representing Northern Ireland has already won a Major and notched his first win of this season at the Honda Classic in March. Although he's struggled quite a bit this season on the PGA circuit, he has stabilized himself by performing rather well in Europe, meaning that he probably won't lose hold of his ranking in the near future. With the Open in a few weeks in his native United Kingdom, he can overtake fellow countryman Luke Donald for the top spot.

2. Webb Simpson

The 26-year-old out of Wake Forest is also in his fifth year as a pro, and just recently won the latest edition of the U.S Open at Olympic Country Club in San Francisco. Due to the approaching date of his second child, he will forgo The Open this season at Royal Lytham St. This eliminates a major champion from the field, and also can possibly affect his world rank, as well as his FedEx cup rank. Webb led the FedEx Cup Playoffs through the final event and came in a disappointing second last season, too. However, he is playing excellent golf as recently, and is currently No.5 in the world.

3. Martin Kaymer

Kaymer peaked last season, becoming the No.1 player in the world for eight weeks. The 27-year-old German has dropped to No.14 since, and has played in limited PGA events. However the eighth year pro has already won a Major (PGA Championship 2010) and has won an amazing 10 tournaments on the European PGA Tour. With a win on either circuit this season, he is likely to re-emerge in the as a top-10 player in the world.

4. Dustin Johnson

Known for his overwhelmingly long drives around the PGA Tour, Johnson has yet to win that elusive first Major. But at 28 years young, the Coastal Carolina graduate is still perfecting his game, placing at No.15 in the world rankings, and recording his sixth career PGA win this season at the FedEx St. Jude Classic. With a runner up finish in last year's British Open, he is looking to make another run at the tournament in two weeks to climb even farther up the rankings.

5. Charl Schwartzel

At 27, the South African has one convincing PGA Tour win at the 2011 Masters Tournament, seven wins on the European Tour, and five on the South African Sunshine Tour. Ranked No.18 in the world, he has gone down 11 positions on the world rankings and has yet to win this season. With 13 career wins since 2004, though, he's got a pretty good shot at getting at least one before the season's up.

6. Rickie Fowler

He is the face of the next generation of golfers worldwide. Known for his colorful outfits and highly competitive nature, the entire golf world is counting on Fowler and McIlroy to be the next Tiger Woods-Phil Mickelson rivalry. Although the Oklahoma State Cowboy only got his first career win this season at the Wells Fargo Championship, he contends in nearly every tournament, and the golf world has extremely high expectations for him

7. Louis Oosthuizen

Oostie barely makes this list at 29 years old, but has been a dominant golfer since winning his first and only Major, the 2010 British Open at St. Andrews. He's added four more international tournament victories to his resume since then. The South African almost followed directly in his fellow countryman and close personal friend Charl Schwartzel's footsteps by winning the 2012 Masters, but lost on the second hole of a playoff to Bubba Watson. Ranked No.20, he will definitely look to win that second major championship at the Open in late July.

8. Jason Day

At 24 years old, Day has shown consistency in his game that goes beyond his years, coming in as a runner-up twice and recording another top-10 finish in only seven career Majors. Although he only has one professional win at the 2010 HPO Byron Nelson Championship, this very consistency has got him up to the No.21 slot on the world ranking, as he continues to refine his game and improve his scoring average.

9. Keegan Bradley

Many professionals say Keegan has one of the best swings on the tour, and he can hit it further than almost anybody. The 26-year-old Bradley out of St. Johns has already won a major championship, the 2011 PGA Championship, as well as the 2011 HP Byron Nelson Championship. He currently ranks as the No.23 player in the world.

10. Francesco Molinari

Molinari is last under-30 player in the top-50 world golf rankings. The Italian and younger brother of fellow Tour player Edoardo Molinari is ranked at No.28 at the moment, but has yet to win on the PGA Tour. However, the 29-year-old has won three times on the Europan Tour, including one World Golf Championship event.
