"I didn't play particularly well but managed to get it around," Grace said. "If we have a great day tomorrow, it's going to be a low scoring round, and if the weather turns bad on us and the wind starts blowing, you'll never know what St. Andrews has got for us."
United States Ryder Cup star Dustin Johnson (67) made the 5-under cut for the final round with a shot to spare on the Old Course at St. Andrews. Martin Kaymer and Peter Hanson each shot 69 to make the cut.
