How Is Slugging Percentage Calculated?
The slugging percentage is calculated by dividing the total bases by the at-bat stats of the player.
Every season the MLB players slugging percentage is calculated to see how efficient they are when it comes to hitting for extra bases.
Since a good slugging percentage represents the hitter's quality and his capabilities, it is no doubt that every player would want to have a good percentage at the end of the season.
When calculating the percentage, the total bases include the hit for a single, a double, a triple, and a home run.
The formula to calculate the slugging percentage would be: Total Bases / At Bats
Total bases = Hit for a single + 2* Hit for a second base + 3* Hit for a third base + 4* Hit for a home run
We can see that since it mainly focuses on the hit for extra bases, it adds value to the player's ability to do such compared to hitting for a single.
What Is At Bats?
At bat is simply the hitter's opportunity to hit the ball pitched by the pitcher toward him when he is on home plate. However, at-bats is not equivalent to the hitter's plate appearance.
A hitter is awarded the plate appearance no matter what happens when he's at the plate. If the hitter gets a walk, is hit by a pitch, hits a sacrifice fly, or in case any other irregularities occur while he is on the home plate, it is counted as a plate appearance.
But the player's at-bat is only counted if his time at the plate as a hitter is not marred by any of the above-mentioned irregularities and he gets an opportunity to hit the pitch against the pitcher.
