Slugging percentage in softball is created for the batter's overall power. SLG in softball is similar to baseball but has greater importance.

Softball is a game similar to baseball. There are different variations of the game, the most famous being fastpitch and slowpitch.

Most things resemble baseball except for some rules, and the ball is typically 11 or 12 inches, depending on the variation. The game goes faster than baseball as the field is smaller and the bases and fielders are close to the home plate.

The other difference is the game is played for seven innings instead of nine, as in baseball. Most of the playing way is similar, except that only underhand pitches are allowed.

Both sports use the same statistics like slugging percentage, on-base percentage, and more to measure the player's ability. SLG is an important statistic in both sports to assess players' hitting capacities.

What Is Slugging Percentage In Softball?

Softball slugging percentage represents the total number of bases scored player per at-bat. It is a statistic describing how well a batter hits the ball.

The SLG is an essential aspect of the game to measure the batter's power at the plate. The value indicates the player's ability to hit extra-base hits and score runs.

The statistic is critical in assessing the hitting prowess of the batter. A batter with a higher SLG is likelier to hit homers and extra bases, becoming a tremendous asset to the club in changing the match's outcome.

With the sport's popularity increasing, the importance of SLG has also increased. Most clubs and coaches now focus on this statistic while choosing players.

Although both statistics evaluate the batter's quality, the SLG differs from the batting average.

While the batting average value is calculated by dividing the total number of hits by the total number of at-bats, however, in SLG, each base hit is given different values.

A double is worth two times a base hit, whereas a triple is valued three times the base hit.

Although in terms of runs scored, a double is not worth twice the base hit, SLG is still an excellent way to evaluate a batter's power as it considers more than just the home run-hitting ability.

In addition, SLG can also be used as a metric to evaluate pitchers. It is described as the slugging rate against; however, this statistic is used less frequently than for the batters.

What Is A Good Slugging Percentage?

Good slugging percentage softball is above .800. University of Florida infielder Skylar Wallace is the NCAA Softball DI league's leader in SLG this season.

The player has an SLG of 1.055. Twenty-one players in the league have an SLG higher than .800 as of 7th May.

In addition, two players have an SLG above 1.000, whereas six players have an SLG above .900. The highest achievable value is 4.000 in SLG. 

If a player homers in his first-ever at-bat, they will have an SLG of 4.000 momentarily. But it is impossible to hold onto it, and most players will have an SLG below 1.000.

On Base Percentage Softball

On-base percentage or OBP refers to the frequency at which the batter reaches the base per plate appearance. OBP and SLG are used together to determine on-base plus slugging or OPS.

OBP is the ratio that describes the batter's time on base to the sum of at-bats, bases on balls hit by pitch, and sacrifice flies.

The batter's time on base is calculated by adding the number of hits, bases on balls, and times hit by the pitch.

However, OBP does not consider the batter reaching bases due to fielding errors, the fielder's choice, uncaught third strikes, obstruction, or the catcher's interference.

The batter's primary goal is to prevent themselves from being struck out. The on-base percentage indicates whether the batter has accomplished that task the best.

Erin Coffer, an infielder at the University of Kentucky, is the current leader in OBP in the NCAA Softball DI league. The player has 55 walks, 48 hits, five hits by pitch, and sacrifice flies to her name with an OBP of 0.628.

She is one of only three players in the league with an on-base percentage above .600. Also, forty-four players have an OBP of .500 or above.

The statistic gained popularity after the 2003 book Moneball focused on the Athletics general manager Billy Beane's use of sabermetrics.

The Dodgers executive Branch Rickey and statistician Allan Roth invented the statistic in the 1940s and 50s. However, it has been part of the MLB's official statistics since 1984.

How To Calculate Slugging Percentage In Softball?

Slugging percentage calculation is done by dividing the total number of bases by the total number of at-bats. Each base hit has different values assigned.

A single is worth one, a double is worth two, a triple is worth three, and a home run is worth four. The following equation is used then to calculate the SLG value:

(1B) +( 2 x 2B) + ( 3 x 3B) + ( 4 x HR) / AB
B = Total number of singles,
2B = Total number of doubles,
3B = Total number of triples,
HR = Total number of home runs and
AB= Total number of at-bats

As statisticians usually don't keep track of single base hits, there is a different way in which you can calculate the value of 1B. You must subtract the sum of doubles, triples, and home runs from the player's total hits.

1B = H - 2B - 3B - HR
where H= Total number of hits

SLG, together with OBP, is called on-base plus slugging. This statistic represents a player's ability to cover bases and hit power shots.
