Mitchell, who started on the back, pulled his drive and then his next drop into the pond on the 377-yard par-4 7th hole, falling to 4 over for the tournament. He added a three-putt bogey on the final hole of the day to finish at 3 under for 36 holes.

Thorbjorn Olesen aced the par-3 eighth and shot a 4-under 67 on Saturday in the 3M Open for a share of the third-round lead with Akshay Bhatia.
