It seems almost unfair that every top, young player gets compared to Tiger Woods, with inevitable question of "is he the new Tiger?" arising sooner rather than later. It happened to world number one Rory McIlroy, and it's happening Spieth. What's the answer you ask? No, he isn't the new Tiger – he's something different, but that doesn't mean he won't be just as great.
It's big talk to say that a man who has just bagged his second major is in the same league as Woods, but Spieth is ticking all the right boxes.
At Chambers Bay on Sunday became just the sixth man to win the season's opening two majors in the same year, and the first to do so since Woods in 2002. At the age of just 21 he is the youngest player to win two career majors since Gene Sarazen in 1922 and the youngest U.S. Open winner since Bobby Jones in 1923.
But it's not just Spieth's record that's so impressive.
One of the key aspects of Spieth's victory at Chambers Bay was that he wasn't at his best. He missed fairways and greens, at times struggled to get his silky smooth putting going and generally was not making the kind of shots that saw him win the Masters. But he didn't let him bother him.
Spieth was often heard chatting to caddy Michael Greller after a bad shot or moment of difficulty. Spieth talks it out and with Greller and then let's it go and moves on.
He ground out a win in at University Place like a seasoned Tour veteran. He nearly threw it away at the 17th after appearing to have it in the bag at the 16th. After missing an eagle putt at the last he then made birdie, a margin which proved enough for victory; it wasn't the smoothest run to victory, but it was a round of great maturity.
A colleague told me this of Spieth: "If I had to choose a champion in a trial by combat where putting was the format, I would choose Spieth". Let's hope neither party finds themselves in such a situation, but the point is that in a tough situation Spieth can be relied on.
The birdie putt at the par-four 16th on Sunday was one of the most impressive putts you'll see. Having seen his chip onto the green hold up unexpectedly, Spieth left himself a tricky birdie putt. But he was able to shrug off the frustration of his second shot to judge the break perfection and watch the ball curl into the corner of the hole.
When Spieth walked back onto the 18th green after winning the Masters to applaud the crowds, he endeared himself to thousands. It was a small gesture, but one that certainly did not go unnoticed. But don't think for a moment that it was just for show now that he was on the big stage.
Ask those who knew Spieth or saw him play even since back in his days as a junior and they will tell you that maturity and humility are cornerstones of Spieth's character – but don't ask him about it. When quizzed on his humility, Spieth responded: “Me speaking about humility is very difficult because that wouldn’t be humility’”… I think we can agree it's genuine.
The 21-year-old's sister Ellie, seven years his junior, has a neurological disorder that puts her on the autism spectrum. Spieth has often spoken of how he is grounded by his sister, and the role that she has played in his success; "Being Ellie's brother humbles me every day of my life," he says. For a man who has achieved so much success in a reasonably short space of time, he remains humble, and his family appears to play a big role in that.
Jack Nicklaus summed it up perfectly when he offered Spieth his congratulations after winning the Masters: "Congratulations to an exceptionally talented young man. That was an incredible performance. Jordan is so beyond his years. I like everything about him. He’s polite, he’s humble, he handles himself so well, on and off the golf course. And he’s obviously a wonderful player and now a Masters champion."
Jordan Spieth is the real deal and look sets for a long run in the upper echelons of golf, and that can only be a good thing for the game.
