-- HAYWARD, Calif. -- Stephan Jaeger shot a 12-under 58 on Thursday in the Web.com Tour's Ellie Mae Classic, the first 58 in a PGA Tour-sanctioned event.
Japan's Ryo Ishikawa shot the only other 58 in major tour play with a 12 under to win the 2010 Crowns on the Japan Tour.
The 27-year-old Jaeger, of Germany, finished with a 10-foot birdie putt on the par-5 ninth at TPC Stonebrae.
"It went in a little fast for my liking," Jaeger said about his final putt. "On a day like that, it'll go in. ... Right now, I'm actually kind of happy to be done, to be honest with you. It's very stressful for you. It's kind of like going on the back nine on Sunday. I'm happy I performed the way I did. It was the icing on the cake, the last hole obviously."
Jaeger broke the Web.com Tour record of 59 held by Notah Begay III, Doug Dunakey, Jason Gore, Will Wilcox and Russell Knox. Six players have shot 59 on the PGA Tour, and one on the PGA Tour Champions.
"Everything went well," Jaeger said. "I was driving the ball well, I was making everything. I got the good breaks."
He was thinking about breaking 60.
"It pretty much was in my head the whole back nine," Jaeger said.
On the final hole, he hit a 3-wood off the tee and hit a layup to 95 yards.
"We had a good strategy for that hole," Jaeger said. "I was going to play it as a three-shot hole and take the bunker out of play off the tee and at worse make par."
Jaeger came to the United States as a foreign-exchange student in 2006. He went to high school for two years in Chattanooga, Tennessee, and played in college at Tennessee-Chattanooga.
The three-time Southern Conference player of the year played both nines in 6-under 29. He birdied Nos. 11 and 13-17 on his opening nine, and Nos. 1-2, 4-6 and 9 on his second nine. He got up-and-down for par on the par-4 seventh and barely missed a 30-footer on the par-4 eighth.
"Even the bad shots, I'd get a good bounce and have like 15 feet and I'd hole that," Jaeger said.
In 88-degree heat with the wind at 8-15 mph, Jaeger was more than 11 strokes below the field average of 69.258. His worst hole was a three-putt par on the par-5 third.
"Other than that, everything went my way," Jaeger said.
Jaeger is 102nd on the money list, with the top 25 at season's end earning PGA Tour cards. The winner Sunday will get $108,000.
"I'd much rather be in the top 25 at the end of the year, with or without the 58," Jaeger said.
Stanford senior Maverick McNealy, the top-ranked amateur in the world, had a 67.
