Unveiling the OPS: A Comprehensive Guide to Measure Batting Performance

Introduction

In the realm of baseball, understanding a batter's offensive prowess is crucial for evaluating their contributions to the team's success. One key statistical tool that provides this insight is the On-Base Plus Slugging (OPS). This metric encapsulates both a batter's ability to reach base and their power-hitting capabilities, providing a comprehensive measure of their overall offensive production.

What is OPS?

OPS is calculated by combining a player's On-Base Percentage (OBP) with their Slugging Percentage (SLG):

OPS = OBP + SLG

OBP measures a batter's ability to reach base safely through hits, walks, or hit by pitches, while SLG quantifies their power by taking into account the total number of bases they advance with their hits, including singles, doubles, triples, and home runs.

Interpreting OPS

Understanding OPS is crucial for evaluating a batter's overall offensive contribution. Typically, the higher a player's OPS, the more valuable and productive they are at the plate. Here's a breakdown of OPS ranges and their implications:

• Below .700: Considered below average, indicating a player struggles to reach base and produce extra-base hits.
• .700-.800: Indicates a solid hitter who effectively reaches base but lacks exceptional power.
• .800-.900: Denotes a high-quality hitter who excels at both reaching base and hitting for power.
• .900-1.000: Exceptional hitters who consistently reach base and hit for power, contributing significantly to their team's success.
• 1.000 or above: Extremely rare and elite level hitters, showcasing exceptional all-around offensive abilities.

According to Major League Baseball (MLB) data, the league average OPS has hovered around .750-.800 in recent years. Players with an OPS consistently above .900 are considered among the best hitters in the league.

Benefits of OPS

OPS offers numerous advantages in assessing a batter's performance:

• Provides a comprehensive measure: Encompasses both reach-base ability and power hitting, offering a holistic view of a player's offensive contributions.
• Easy to understand: Unlike other advanced metrics, OPS is straightforward and easy to interpret, making it accessible to baseball fans of all levels.
• Tracks historical trends: OPS data is available for previous seasons, allowing analysts and fans to track a player's offensive performance over time.
• Identifies potential future stars: By identifying players with high OPS in the minor leagues, teams can potentially uncover future offensive threats.

Factors Influencing OPS

Several factors can contribute to a batter's OPS:

• Contact ability: Batters who make solid contact with the ball are more likely to reach base and generate extra-base hits.
• Plate discipline: Batters who recognize good pitches and avoid swinging at bad pitches are more prone to walks and consequently, higher OBP.
• Power: Batters who possess raw power can produce extra-base hits and home runs, boosting their SLG.
• Batting environment: The type of ballpark (e.g., hitter-friendly or pitcher-friendly) and the quality of opposing pitching can influence a batter's OPS.

Stories Illustrating the Importance of OPS

Here are examples that emphasize the significance of OPS in evaluating hitters:

Story 1:

In 2021, Mike Trout posted an OPS of 1.090, leading MLB and setting a new career high. Trout's exceptional combination of reach-base ability (OBP of .460) and power (SLG of .630) showcased his dominance as an all-around offensive force.

What we learn: High OPS indicates a hitter's exceptional ability to get on base and hit for power, making them indispensable to their team.

Story 2:

In 2018, Christian Yelich won the National League MVP award with an OPS of .971. Yelich's impressive OBP of .442 and SLG of .536 demonstrated his consistency at reaching base and producing extra-base hits.

What we learn: A balanced blend of OBP and SLG in OPS calculation highlights a player's ability to both get on base and generate power, making them a significant contributor to team success.

Story 3:

In 2022, Aaron Judge set a new American League single-season home run record with 62. Despite his remarkable power display, Judge's OPS of .989 suggests his contributions extended beyond home runs. His high OBP of .425 underlined his consistent ability to reach base through various means.

What we learn: While power hitting is impressive, the combination of power and reach-base ability showcased by Judge's high OPS is fundamental to a player's overall offensive impact.

Why OPS Matters

OPS is a pivotal metric in assessing a batter's offensive capabilities because it:

• Provides a comprehensive evaluation of both reach-base ability and power hitting.
• Allows for comparisons between players, teams, and seasons.
• Helps identify potential offensive threats and undervalued players.
• Contributes to overall team success by measuring the ability of hitters to drive in runs.

A3: Leadoff hitters typically focus on reaching base, so an OPS in the range of .750-.850 is considered solid.

Q4: Can OPS be used to predict future hitting performance?
A4: While OPS is a good indicator of present offensive production, its ability to predict future performance is not as reliable, as many other factors can influence a player's future success.

Q5: How does OPS compare to other batting metrics?
A5: OPS is more comprehensive than batting average alone, as it combines both reach-base ability and power hitting. However, other advanced metrics, such as Weighted On-Base Average (wOBA) and Expected Weighted On-Base Average (xwOBA), offer additional insights into a hitter's performance.

Q6: Is there a minimum number of plate appearances required for OPS to be meaningful?
A6: To ensure an accurate representation of a player's ability, a minimum of 250-300 plate appearances is generally considered necessary for OPS to be meaningful.
