Slugging percentage is a baseball statistic that measures a player's power-hitting ability. It is calculated by adding a player's total number of bases earned from hits and dividing that number by their total at-bats. The formula is: (singles + 2×doubles + 3×triples + 4×home runs) / at-bats. This statistic provides insight into how effectively a player can hit for extra bases, reflecting their ability to drive in runs and contribute to the team's offense. A higher slugging percentage indicates a more powerful hitter, making it an important metric for evaluating player performance in Major League Baseball.
