1. What is Batting Average Against?

Batting Average Against (BAA) is a baseball statistic that measures how often a pitcher allows hits to batters. It's calculated as the ratio of hits allowed to at bats against, expressed as a percentage.

2. How Does the Calculator Work?

The calculator uses the Batting Average Against formula:

Where:

• Hits Allowed — Number of hits given up by the pitcher
• At Bats Against — Number of at bats faced by the pitcher

Explanation: The formula shows what percentage of at bats result in hits against the pitcher.

3. Importance of Batting Average Against

Details: BAA is a key metric for evaluating pitcher performance. Lower values indicate better performance, with elite pitchers typically having BAAs below .200 (20%).

4. Using the Calculator

Tips: Enter the total hits allowed and total at bats against. Both values must be non-negative integers, with at bats greater than 0.

5. Frequently Asked Questions (FAQ)

Q1: What's considered a good Batting Average Against?
A: Below .200 (20%) is excellent, .200-.250 is good, .250-.300 is average, and above .300 is poor.

Q2: How does BAA differ from ERA?
A: BAA measures frequency of hits allowed, while ERA measures runs allowed per 9 innings. Both evaluate pitchers but focus on different aspects.

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

Q4: What's the league average BAA?
A: Typically around .250 (25%) in MLB, but varies by season and league.

Q5: Can BAA predict future performance?
A: While useful, BAA should be considered with other stats as it doesn't account for quality of contact or defense.
