After driving his tee shot into the rough, Jason Dufner needed to scramble to save par on No. 18. A good approach shot left him with a makeable par putt, but Dufner appeared to push the ball to the right.
He came out of his stance and it looked like the ball would sit on the lip before it suddenly took a left turn and dropped in.
The last second and unexpected turn left allowed Dufner to save par and remain within one stroke of the lead. He'll now play with Jim Furyk in the final group on Sunday.
