Wilh Church and Klinzmann out I thought the race would be a breeze. It wasn't." McClure got the upper hand on West a few times in lhe middle laps, then eased his pace when he began slipping around. McClure kept close enough tabs on West to be in position to take advantage of any trouble. West didn't make any mistakes.

"It was a tough race and I really had LO work for it," said a very happy Labrosse in winner's circle. "Kevin wouldn't let up, but I knew I had an edge in turns two and three and I was saving that strategy for the last lap." Brunson knew his race was nearly over when Labrosse got past him in turn three on the final lap. "Once Alan got past I knew couldn't retake the lead before the fini~h unless he made a mistake. I tried to force one, but he didn't budge." "When I lost the draft of Alan and Kevin I lost any real chance of staying with them," said Franklin.
