<P> In Major League Baseball playoff games are not complete until the trailing team has batted nine innings . This rule also applies for tiebreaker games for playoff positions . </P> <P> Other professional sports utilize similar rules regarding "official" games / events . </P> <P> Most codes of motorsport declare a race "official" with an official result if just three laps are completed, though only half the normal championship points are awarded if less than 75% of the race distance (rounded up to the nearest whole lap) is completed . If more than 75% of the race is completed, full points are awarded . </P> <P> The major exception applies in the United States, mainly in NASCAR and INDYCAR, where races must go at the next full lap after halfway . A race is considered "official" if it has completed half the scheduled distance plus one additional lap . For instance, the Indianapolis 500 (200 laps) must complete 101 laps to be considered official . </P>
