The victory was Keselowski’s first of the season and the seventh of his career. If the race had begun five minutes earlier, however, Keselowski said he wouldn’t have started it, much less won it. Keselowski went to the infield care center after a late wreck in the Cup race. Doctors measured his carbon monoxide level at 13, far in excess of the allowable 5. Intense oxygen treatment finally brought his carbon monoxide level into the acceptable range, moments before the command to start engines.
