In Turnberry, Scotland, two British golfers were forced to pull out of the British Amateur championships because they gave chase to a would-be car thief at 2 a.m. The two golfers bumped into each other in the darkness as they lunged for the mystery man, and both damaged their wrists in the collision. James Bedford, 18, and Richard Lane, 21, were awakened in their hotel in the early hours when they heard sounds from the parking lot and saw someone trying to open car doors. With a third golfer, Enil Fox, they decided to investigate and stalked the mystery figure. But as they pounced for him in the darkness they crashed into each other and the thief ran off. He was eventually caught by police. Lane withdrew before yesterday's first round with strained ligaments, and Bedford was forced to pull out after only six holes in discomfort from cuts. Lane said, "The organizers were very good about it and returned our 15 pounds ($24) entry fee, but it's still a long way to come to bump into a friend and injure yourself. Now we are going home before anything else happens." . . .

Philip Parkin, 21, a Welshman studying at Texas A&M, grabbed a one-stroke lead after the first round of the tournament with a three-under-par 66 on the easier Arran course.

Another day of stroke play today whittles the field to 64 for the match play beginning Wednesday . . .
