Two years ago, a 23-year-old making just his ninth start on the PGA Tour, playing on a sponsor’s exemption, briefly took the lead in the final round of the Zurich Classic, making an eagle and six birdies over his first 13 holes. Ultimately, the promising young player couldn’t keep it going, making a couple of nervous three-putt bogeys late in the day to finish fourth in the water-logged tournament that spilled over to Monday and was shortened to 54 holes. Still, it was a good start, the kind of moment that has often proved a launching point for many a career if not stardom. A final-round 64 at TPC Louisiana and high finish earned the kid who’d once shot 57 in the Alabama Boys State Junior Championship and helped lead the University of Alabama to two national championships more than $300,000 and enough non-member FedEx Cup points to qualify for the Web.com Tour Finals, where he would finish 22nd on the money list and earn his card for the big tour in 2016-’17. After the performance in New Orleans, his takeaway was that he could hang at the highest level of the sport.
