1. What is OPS?

OPS (On-base Plus Slugging) is a baseball statistic that combines a player's ability to reach base (OBP) with their power hitting (SLG). It provides a simple but effective measure of a player's overall offensive contribution.

2. How Does the Calculator Work?

The calculator uses the simple OPS formula:

Where:

• \( OBP \) — On-base percentage (hits + walks + HBP divided by plate appearances)
• \( SLG \) — Slugging percentage (total bases divided by at-bats)

Explanation: OPS combines two key offensive metrics to give a more complete picture of a player's offensive value than either statistic alone.

3. Importance of OPS

Details: OPS correlates well with run production and is widely used to evaluate hitters. It's simple to calculate but provides meaningful insight into a player's offensive performance.

4. Using the Calculator

Tips: Enter OBP and SLG as decimals (e.g., .350 not 35%). Both values must be between 0-1 for OBP and 0-4 for SLG.

5. Frequently Asked Questions (FAQ)

Q1: What is a good OPS?
A: .800+ is excellent, .700-.799 is good, .600-.699 is average, below .600 is poor. League average typically ranges from .700-.750.

Q2: Why not use batting average?
A: Batting average ignores walks and power. OPS accounts for both getting on base and hitting for extra bases.

Q3: What are the limitations of OPS?
A: It treats OBP and SLG as equally valuable (OBP is actually more valuable), and doesn't account for baserunning or situational hitting.

Q4: What's the highest possible OPS?
A: The theoretical maximum is 5.000 (1.000 OBP + 4.000 SLG), though no player has ever approached this.

Q5: How does OPS+ differ from OPS?
A: OPS+ adjusts for park and league factors, with 100 being league average. It provides better context for comparing players across eras and ballparks.
