Single Season Leaders for On Base Plus Slugging in the National League

The on base percentage statistic was originally created by Branch Rickey and Allan Roth in the 1950's as a means to measure the percentage of times a player reaches any base. It did not originally include the sacrifice fly denomination but when it was officially adapted in 1984 it appeared using the formula written above. Slugging Average was developed later and the two were combined to create On Base Plus Slugging.

Note: One-hundred single season games played are needed to make this list of the one-hundred (100) greatest on base plus slugging National League leaders, raw averages are presented in parenthesis to further distinguish the top one-hundred, and a bold faced entry denotes that the player was active during the previous Major League season.
"People talk a lot about all my personal records and the fact that I've never won that World Series ring. I want both. I wouldn't trade anything I've done for anything else. You do what you need to do as a ballplayer when you go out on the field all year." - Barry Bonds in Barry's Journal (Barry Bonds, 10/03/2004)
