Marc Leishman is the leader through 18 holes of the AT&T Byron Nelson Classic at Trinity Forest Golf Club in Dallas.
Leishman shot a 10-under 61 for the first round, giving him a three-shot lead over J.J. Spaun and Jimmy Walker. Eight golfers are tied for fourth at six under.
According to the Dallas Morning News' Brad Townsend, Leishman finished one shot short of tying a tournament record for the lowest single-round score. He needed to sink a 26-foot putt on the 18th tee in order to get to 11 under but settled for par.
The PGA Tour noted it was still a career-best for Leishman:
Leishman got his round off to a great start, carding an eagle on the opening hole. His second shot landed within feet of the cup, leaving him a simple putt to move to two under. The PGA Tour shared a replay:
As evidenced by his score, Leishman didn't slow down too much over the remainder of his day. He made the turn at four under before starting the back nine with three straight birdies. Then came an eagle on No. 14 and a birdie on No. 17.
According to PGATour.com, Leishman had a 100 percent driving accuracy and reached all but one of the greens in regulation.
As great as he played, Leishman's three-shot lead doesn't offer a ton of security considering how many golfers are hovering near the top of the leaderboard.
Both Spaun and Walker had similar rounds, as their best work came on the front nine. Spaun carded a six-under 30, while Walker shot a five-under 31. Walker's momentum stalled a bit, and WFAA's Mike Leslie thought he was a bit fortunate to get to six under on No. 14:
Pretty remarkable birdie from Jimmy Walker on 14, to move into a tie for third at -6. His drive was way right, had to get a ruling and relief from the path. Then hit a screamer of a long iron, to set up a two-putt 4. #ATTByronNelson— Mike Leslie (@MikeLeslieWFAA) May 17, 2018
Walker played collegiately at Baylor University, so many in attendance at Trinity Forest Golf Club were likely happy to see him chasing down Leishman.
Another college star from Texas didn't fare so well. Jordan Spieth never got into a groove and sits eight shots back of Leishman after the first round. In general, Spieth's performance has dipped since his third-place finish at the Masters. He missed the cut of the Zurich Classic and tied for 41st at the Players Championship.
Two shots separate 23rd from 57th, so it wouldn't take much for Spieth to make a big climb up the leaderboard over the coming days. But he has left himself a big hole if he's going to register his first victory of the 2018 season.
Whereas Spieth is at least in position to continue playing through the weekend, it will take a big effort from Sergio Garcia and Hideki Matsuyama just to make the cut. They're both at one over and in a tie for 122nd.
