SILVIS, Ill. — Doug Ghim holed out for eagle on the par-4 sixth hole and kept bogeys off his card on a day of low scoring Thursday. He opened with a 9-under 62 in a bid to become the latest first-time PGA Tour winner at the John Deere Classic.
Ghim had a one-shot lead over Max Homa and Austin Eckroat at the TPC Deere Run, where the winning score has been 20-under par or lower 12 of the last 15 years.
He has been around long enough — six years on the PGA Tour, 160 tour starts as a pro — to know it's only a start. The conditions were so ideal Ghim wasn't even sure his 62 would hold up as the lead by the end of the day.
With a little more wind in the afternoon, the best anyone could do was 65 by four players, including Cameron Champ and Mexico Open winner Brian Campbell.
''Honestly, any time you can get to 20 under or better you're going to have a chance,'' Ghim said. ''It's still golf. It's still a challenge. You have to hit fairways. I hit a lot of them today. So just trying to shoot forwards of 6 under every day and see where that puts me.''
Aldrich Potgieter of South Africa, the 20-year-old coming off his first PGA Tour win last week in Detroit, was challenging for the lead until he stalled at the end of his round, took bogey on the par-5 17th and had to settle for a 67.
The John Deere Classic has produced 24 first-time winners, the most of any PGA Tour event since 1970, a list that included Davis Thompson last year, Bryson DeChambeau in 2017 and Jordan Spieth in 2013.
Homa and Eckroat have won before, and both are trying to rediscover their games. Homa gets the most attention, particularly since he played in the last Ryder Cup and reached No. 8 in the world until going into a slump that includes new equipment, a new coach and new caddie.
