1. What is Batting Average Against?

Batting Average Against (BAA) is a statistic in baseball that measures how often a pitcher allows hits to batters. It's calculated by dividing the number of hits allowed by the number of at bats against the pitcher.

2. How Does the Calculator Work?

The calculator uses the BAA formula:

Where:

• Hits Allowed — Total hits given up by the pitcher
• At Bats Against — Total official at bats against the pitcher

Explanation: The result is typically expressed as a decimal rounded to three places (e.g., 0.250).

3. Importance of BAA Calculation

Details: BAA is a key metric for evaluating pitcher performance. Lower BAAs indicate better performance, with elite pitchers typically maintaining BAAs below .220.

4. Using the Calculator

Tips: Enter whole numbers for hits allowed and at bats against. At bats against must be greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What's considered a good BAA?
A: Generally, below .250 is good, below .220 is excellent, and below .200 is exceptional.

Q2: How does BAA differ from ERA?
A: BAA measures frequency of hits allowed, while ERA measures runs allowed per 9 innings.

Q3: Does BAA include walks?
A: No, BAA only includes official at bats (which exclude walks, sacrifices, and hit by pitches).

Q4: What's the league average BAA?
A: Typically around .250, but varies by season and league.

Q5: Can BAA be greater than 1.000?
A: No, since hits can't exceed at bats in the calculation, maximum BAA is 1.000.
