Baseball often use statistics. It is said that OPS(On-base plus slugging) is related to the score. OPS is a sum of a player's on-base percentage and slugging percentage.

- on-base percentage :
**(his + base on balls + hit by pitch) ÷ (at bats + base on balls + hit by pitch + sacrifice flies)** - slugging percentage :
**(single hits + two-base hits x 2 + three-base hits x 3 + homeruns x 4) ÷ at bats**
