Scottie Scheffler lost the lead at the halfway stage of the Hero World Challenge after making a rare double bogey.
Scheffler took six on 16 to fall one shot off the five-way lead shared by Cameron Young, Hideki Matsuyama, Wyndham Clark, JJ Spaun and Akshay Bhatia on 10 under-par.
The world number one suffered a penalty stroke after driving his ball into a bush at the Albany course in the Bahamas.
Scheffler's third shot struck another bush before flying into the fairway and he then missed a putt from distance for a bogey five.
"I did some good things out there," Scheffler told the Golf Channel after signing for a 69.
"Few too many mistakes, but overall another solid day on the course."
Young produced the shot of the day on 15, chipping in for eagle on his way to a stunning 64 that also contained seven birdies and a bogey on 18.
Alex Noren and Sepp Straka joined Scheffler on nine-under, with England's Justin Rose one stroke further back after a 68.
Scotland's Robert MacIntyre is tied 14th on four-under after a 67, six shots better than his opening round of 73.
