MacIntyre, the lefty from Scotland, got out of several jams, none bigger than the short fifth hole when he drove over a hazard line into the bushes. He decided to hack out, and it shot some 70 feet away for a putt straight down a series of ridges.

No one had a lower score than Robert MacIntyre both of those rounds at the BMW Championship, and his reward for his 6-under 64 on Friday was a five-shot lead over Scottie Scheffler going into the weekend.
