 Turning to sports this morning, Xander Shelfley went from the most nerve-wracking putt of his life to the coolest walk toward an 18th green he ever imagined. He won a nail-biter at the PGA Championship in May and delivered a masterpiece Sunday in the British Open. Two different finishes, two different feelings, one major conclusion. Shelfley has more than enough game and all the confidence in the world to win the biggest championships. Questioned at the start of the season whether he could win a major, he now has two of them.
