Golf hasn't entered a new era

World number two Jordan Spieth is not yet ready to say golf has entered a new era.

Spieth, 22, has claimed two majors this year, while Jason Day (PGA Championship) and Zach Johnson (The Open) were the other winners.

Day, Spieth and Rory McIlroy are the top three in the rankings and the highly rated Rickie Fowler is fifth.

But Spieth said there needed to be consistent dominance.

''I think it's a bit soon,'' Spieth said, via Golf.com.

''For Rory, it's different because it's been consistent for years now. Jason and I, we've played solid golf the last few years.

"In order to create an era, you almost need a decade of years like this. Sure, we have the potential to do it. But this was the first year of it.

"But unless we keep our heads down ... unless we're aware of it, and it drives us, and we get the right breaks, there's a lot of factors. So maybe it's a bit premature to say that."

The timing of the new era comes at a perfect time, as one of the game's biggest stars, Tiger Woods, has undergone back surgery.

Woods has struggled this year, posting just one top 10, and may never be the same golfer that won 14 majors

Now, the game of golf is in the hands of young stars such as Spieth, McIlroy, Day and Fowler.

''I believe we'll all battle it out,'' Spieth said.

''But to battle it out on the highest stages and to stay up in the ranking and all that ... it can happen. But it's going to take more than just this year."
