HAYWARD, Calif. (AP) Stephan Jaeger shot a 12-under 58 on Thursday in the Web.com Tour's Ellie Mae Classic to match the lowest score in major tour play.
The 27-year-old German player finished the round with a birdie on the par-5 18th at TPC Stonebrae.
Japan's Ryo Ishikawa also shot a 12-under 58 to win the 2010 Crowns on the Japan Tour.
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 in official PGA Tour events.
Jaeger played both nines in 6-under 29. He birdied Nos. 11, 13-17 on his opening nine, and Nos. 1-2, 4-6 and 9 on his second nine.
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.
Josh Teater, Xander Schauffele and Rhein Gibson were tied for second at 62.
