In sports, a winning sport refers to a consecutive number of games won. A winning streak begins after the third consecutive victory, back-to-back wins is only considered two consecutive victories. A winning streak can be held by a team, as in baseball, football, basketball, hockey, or by an individual, as in tennis. A winning streak that extends through a single season, i.e. every game in the season is won, is known as a perfect season.

                          
                      

A winning streak is not to be confused with an unbeaten sport, where teams can tie as well as win to maintain their sport. For example, if a football team wins four games in a row, plays a draw, wins three more, plays two draws in a row, and then loses, they had a 10-game unbeaten sport. Their longest winning sport in this sequence was four. If a sports league declares overtime losses different from regulation losses in that they are scored like ties (such as ice hockey leagues where there is both a 3-on-3 overtime and a shootout to break ties), an unbeaten sport continues if at the end of regulation, the game is tied. This is because losses in overtime and shootout are declared regulation ties, and teams accumulate one point for the draw. As such, if a team wins four consecutive games, then loses two consecutive games in overtime, then loses in a shootout, and then wins three consecutive games, that team has a ten-game unbeaten stop.
