2021 AT&T Byron Nelson leaderboard: Jordan Spieth goes low with thrilling 63 to sit on top after Round 1

The best golfer in the world over the last three months was again the best on Thursday

Following a month off and a short recovery after testing positive for COVID-19, nobody really knew what to expect from Jordan Spieth in Round 1 of the 2021 AT&T Byron Nelson at TPC Craig Ranch. So of course, he delivered the full Jordan Spieth Experience. There were chunked chips, thinned irons, insane recovery shots and lots and lots and lots of birdies. Spieth shot a 9-under 63 in Round 1, but his scorecard belies the roller coaster everyone watched for four hours on Thursday afternoon. Chief among the entertainment was an approach from a very Spiethian position on the 12th hole. After Spieth drove it way out to the right on the 558-yard hole, Golf Channel broadcaster Colt Knost -- who was following Spieth's group -- was hollering about how Spieth should just chip out and get to a more playable position on the long par 5, and I don't think anyone watching disagreed. So of course, Spieth hit a 3-wood from 247 yards to 9 feet to setup an eagle attempt (which he, of course, missed).
