A "comeback victory" refers to a situation in sports or competitions where a team or individual overcomes a significant deficit to win the game or match. This often involves a dramatic shift in performance, where the losing side rallies to score more points or goals, surprising both opponents and spectators. Comeback victories are celebrated for their excitement and unpredictability. These victories can occur in various sports, including football, basketball, and tennis. Famous examples include the New England Patriots in Super Bowl LI, where they overcame a 28-3 deficit, and Roger Federer at the 2017 Australian Open, where he came back from a set down to win the title.
