On-Base Plus Slugging (OPS) is a baseball statistic that combines a player's ability to get on base and their power-hitting skills. It is calculated by adding two key metrics: On-Base Percentage (OBP) and Slugging Percentage (SLG). OBP measures how often a player reaches base, while SLG evaluates the total number of bases a player records per at-bat. OPS provides a comprehensive view of a player's offensive performance, making it easier to compare players across different eras and positions. A higher OPS indicates a more productive hitter, as it reflects both their ability to reach base and their capacity to hit for power.
