Baseball statistics are some of the most scrutinized numbers in all of sports. From hitting percentages to earned run averages, coaches and managers are always trying to get a leg up by using statistics to evaluate their team and opponents. OPS is a hitting stat that stands for "on base plus slugging" and is actually a combination of two different statistical categories.

Step 1

Add the total number of times a player got on base during the season. This should include hits, bases on balls, and the number of times the player got hit by a pitch or got on base as a result of a fielder's choice.

Step 2

Divide that number by the total number of at-bats during the season. This includes non-recorded at-bats for bases on balls and sacrifice flies. The number---in the form of a decimal, such as .336---is the player's on-base percentage.

Step 3

Add the total number of bases the player earned from hits. For instance, if a player hit a single, it counts as one base. Doubles count as two bases, triples count as three and home runs count as four bases.

Step 4

Divide the total number of bases by the total number of at-bats for the season. Do not include nonrecorded at-bats for bases on balls and sacrifice flies. The number---also in the form of a decimal---is the player's slugging percentage.

Step 5

Add the two decimal numbers together to determine the player's on base plus slugging percentage, or OPS. For example, if the player's on-base percentage is .336 and his slugging percentage is .767, the OPS would be 1.103.
