A lot of the pre-tournament chatter for the 106th PGA Championship at Valhalla Golf Club this week was about heavy favorite Scottie Scheffler, world No. 2 Rory McIlroy, and the hometown favorite Justin Thomas.But once the tournament started, it didn’t take long for Xander Schauffele to join that conversation.Schauffele fired a 9-under-par 62 in the first round, setting a new Valhalla course record and a new PGA Championship record. It’s tied for the lowest round in a major championship ever.“It’s a great start to a big tournament,” Schauffele said. “One I am obviously going to take. But it’s just Thursday, that’s about it.”The record-setting round eclipsed the old competitive course record of 63 set in the 2000 PGA by Jose Maria Olazabal.Schauffele had also fired a 62 at the 2023 U.S. Open at the Los Angeles Country Club. Schauffele is now the only man in the history of professional golf to shoot multiple rounds of 62 in majors.“I’ll take 62 at a major championship any day,” Schauffele said.The 30-year-old Schauffele, who has seven career PGA Tour wins, is widely considered the best player to have never won a major. He has the lowest all-time career first-round scoring average in major championship play among those who have appeared in at least 25 majors, according to the Elias Sports Bureau.In this one, he shot a 31 on the back nine after teeing off at No. 10 and then had 31 on the front nine.“In terms of wanting to go practice right now, there's always shots you can kind of pick apart or chips that you can pick apart that you felt like you could have hit better, but I'm very content with how I played,” he said.The chatter around Schauffele was perhaps a little low because of last week. He led the Wells Fargo Championship by two strokes heading to hole No. 8 on the final day, but Rory McIlroy ended up winning that event by five strokes.But he put that behind him and started the PGA with a bang.“I think not winning makes you want to win more, as weird as that is,” Schauffele said. “For me, at least, I react to it, and I want it more and more and more, and it makes me want to work harder and harder and harder. The top feels far away, and I feel like I have a lot of work to do. But just slowly chipping away at it. It’s a good start.”Schauffele has a three-shot lead on the players from the morning round.Tony Finau and Sahith Theegala both shot 6-under 65, while Rory McIlroy - the 2014 PGA champion at Valhalla - and Robert Macintyre but had 66s. Ben Kohles shot 67 in his PGA debut. The last player to shoot 4-under or better in the first round of their PGA debut was Scottie Scheffler in 2020. He went on to finish tied for fourth.Schauffele has a three-shot lead heading into round two.Tony Finau and Sahith Theegala both shot six-under 65, while Rory McIlroy, the 2014 PGA Champion at Valhalla, and Robert Macintyre had 66s in the morning round.The three lowest scores in the afternoon rounds were 66s from Tom Kim, Tom Hoge, and Thomas Derry.Six players shot 67, including defending PGA Champion Brooks Koepka, Scottie Scheffler, and Collin Morikawa, who birdied seven of the last 13 holes.Second round play will begin Friday morning at 7:15 a.m.
