A push in sports betting can occur for several reasons, primarily centering around the final score aligning perfectly with the betting line. One common scenario is when a game has a point spread set at a specific number, and the favorite wins by that exact margin; for instance, if a basketball team is a 4-point favorite and they win by exactly 4 points, it results in a push. Similarly, in over/under bets, if the total points scored by both teams match the set line perfectly, such as an over/under of 55 points with a final score of 28-27 (totaling 55), it also results in a push.
