<P> In high school basketball, many states have a "continuous clock" rule, similar to American football, which takes effect in the second half after a lead grows to a prescribed point (in Iowa, 35 points or more; in Kansas, 30 points or more but only in the fourth quarter). The clock stops only for charged, officials' or injury time - outs; or at the end of the third quarter . The clock would not stop when would normally stop, such as for fouls, free throws, out - of - bounds plays or substitutions . </P> <P> The rules vary when normal timing procedures take effect after a lead is diminished (such as because of the trailing team's rally); for instance, in Iowa, normal timing procedures are enforced if the lead is lowered to 25 points but re-instituted once the lead grows back to 35 or more points . By comparison, in Kansas, if the running clock is triggered, it will not stop except for a timeout or an injury even if the differential is reduced to under 30 points . As with other sports, some states offer provisions to allow a team to end the game early by mutual decision of the coaches (for instance, if a large lead continues to grow and the talent disparity is obvious). </P> <P> In American collegiate wrestling and high school wrestling, a wrestler wins by technical fall, and the match ends, if he builds a 15 - point lead . If a wrestler gains a 15 - point lead by having his opponent in a near - fall, the referee will allow the offensive wrestler the opportunity to win by fall without liability to be reversed and pinned . The bout ends when a fall is awarded or the near - fall ends . </P>
