Chris Thompson shot the greatest round in the 102-year history of Lawrence Country Club on Friday and left the course in a miserable mood.

Such is golf.

A professional golfer and former All-American at Kansas University, Thompson broke his own course record by firing a 60 from the back tees, but missed a shot at the first sub-60 round of his life on any course by carding a double-bogey 6 on the 18th hole.

“I was nauseous, to be honest with you,” Thompson said. “That’s as bad as I’ve ever felt walking off a golf course. In the grand scheme of things, I wasn’t playing for money. Shooting 58 or 59 is not going to advance my career in any way, but it’s something I’ve never done, and I wanted to do it pretty bad.”

Thompson’s front nine: birdie, par, birdie, birdie, par, birdie, birdie, birdie, birdie for a 28. The back side: par, birdie, birdie, birdie, eagle, par, par, par, double bogey for a 32.

“I really wasn’t thinking about it until I holed out on 14 for a 2 from 70 (yards),” Thompson said. “Then it was like, ‘Now it’s something to pay attention to.'”

It was at that point that he cooled off, going four holes in a row without a birdie without going back-to-back holes without a birdie or better before that.

Thompson didn’t second-guess himself for thinking about breaking 60.

“I’m not sure it’s possible for that not to occur,” Thompson said. “I hit almost every shot as good as I can and just bladed a chip on the last hole. I had a really good short game. Just hit a terrible shot. Just one of those things that leaves a bad taste in your mouth.”

Thompson’s second shot on the par 4 No. 18 that had a back pin rolled to a stop on the courtesy cup behind the green.

“I had a chip to shoot 57,” he said. “I’m not even thinking about not being in the 50s at that point. Terrible chip (to the front of the green), three-putted coming back. All of a sudden, 60.”

Gary Allen, Greg Sharp, Josh Williams and Brad Ziegler joined Thompson for his historic-yet-frustrating round Friday. Sharp said he thought Thompson would have gone into the 18th hole at 13-under par if not for a fire truck siren sounding in the middle of Thompson’s four-foot putting stroke on No. 17.

Thompson, 39, a resident of Lawrence and native of Independence, played on the Web.com Tour (then known as the Nike Tour) in 2007 and shot a 60 in the opening round of the Cox Classic that year. He has not made it back onto that tour since then, but came close several times, including at the past two qualifying schools, only to miss with disappointing final rounds.

Thompson has qualified for two PGA Tour events, both in 2014. He made the cut at the Byron Nelson championship and qualified for the U.S. Open, missing the cut at Pinehurst.

He attempted to qualify for the past two PGA Tour events, but fell two shots short both times with rounds of 4-under par and 5-under par.

Thompson twice shot 61 from the tips at LCC and once from the bronze tees. PGA touring pro Gary Woodland tied Thompson’s course record last year, but fell out of the LCC record book Friday.
