1. What is Slugging Percentage?

Slugging Percentage (SLG) is a baseball statistic that measures the power of a hitter by calculating total bases per at bat. Unlike batting average, it gives more weight to extra-base hits.

2. How Does the Calculator Work?

The calculator uses the slugging percentage formula:

\[ SLG = \frac{(1B + 2 \times 2B + 3 \times 3B + 4 \times HR)}{AB} \]

Where:

Explanation: Each type of hit is weighted by the number of bases achieved (1 for single, 2 for double, etc.), then divided by total at bats.

3. Importance of Slugging Percentage

Details: SLG is a key metric for evaluating a hitter's power and overall offensive value. It's often used alongside on-base percentage to calculate OPS (On-base Plus Slugging).

4. Using the Calculator

Tips: Enter the count of each type of hit and total at bats. All values must be non-negative integers, and at bats must be greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is a good slugging percentage?
A: In MLB, .450 is above average, .550 is excellent, and anything over .600 is exceptional. The league average typically ranges between .400-.420.

Q2: How does SLG differ from batting average?
A: Batting average counts all hits equally (total hits/at bats), while SLG weights hits by bases gained.

Q3: What's the highest possible slugging percentage?
A: The theoretical maximum is 4.000 (a home run every at bat), though no player has ever finished a season above .800.

Q4: Does SLG include walks?
A: No, SLG only considers hits in at bats. Walks and other plate appearances that aren't at bats don't count.

Q5: Why is SLG important in evaluating players?
A: It better reflects a player's power and run-producing ability than batting average alone.
