That belonged to Spieth, the phenom from Texas who impressed so many by not only winning the Masters but the grace and composure he showed while doing it. He spoke after that win about bringing a present home to his special needs sister, and it was clear that meant almost as much to him as winning his first green jacket.

He’s now halfway to history, yet still barely old enough to drink. The last player who did things like Spieth was named Tiger Woods, which seems so long ago.

Now he’s the youngest since Bobby Jones nearly a century ago to win back-to-back major championships. Spieth has a chance to do what even Woods couldn’t and win all four of golf’s major tournaments in one year.

Watching him Sunday on the crunchy greens at Chambers Bay, it was hard not to get the sense that he’s only just begun.
