On-base percentage plus slugging percentage — a one-number summary of a hitter's ability to reach base and to hit for power. Adding the two rates is a convenience rather than a weighted model (a point of OBP is worth more runs than a point of SLG), and OPS is not adjusted for league or ballpark; OPS+ is.
