Baseball OPS Calculation

1. "At bats (AB)" "Hits (H)" "Doubles (2B)" "Triple (3B)" "Home runs" (HR), Walk (BB), Hit by Pitch (HBP), and Sacrifice Fly (SF) are entered.
2. Automatically calculates "On-base percentage (OBP)" and "Slugging percentage (SLG ) and "OPS" will be calculated.
3. Enter "League Average OPS" and "OPS CPRE" will be calculated.

OPS (On-base Plus Slugging) is an index for comprehensively evaluating batting performance in baseball. OPS is a measure of a player's on-base percentage ( OPS is a combination of OBP and slugging percentage (SLG), and expresses a player's batting power in a single number.

OPS is a simple metric that evaluates a player's overall batting power. It is a widely used metric for It is a useful indicator for comprehensively judging a player's batting performance because it simultaneously evaluates both the player's "ability to get on base" and "ability to advance to the base (slugging power)."

• < High OPS: A player with both a high on-base percentage and a high slugging percentage is considered to be a very good hitter in the game. An OPS of 0.900 or higher is considered to be a very good hitter.
• Low OPSPlayers with low on-base percentage and slugging percentage are considered to have poor batting ability, and if their OPS is below 0.700, they are usually required to improve their batting. Masu.

OPS calculation formula

OPS = On-base percentage (OBP) + Slugging percentage (SLG)

Calculation of on-base percentage (OBP) Formula

On-base percentage is an indicator of how often a batter can reach base. It calculates the percentage of times a batter reaches base due to a hit, walk, hit by pitch, etc.

On-base percentage (OBP) = (number of hits (H) + walks (BB) + hit by pitch (HBP)) / (number of at-bats (AB) + walks (BB) + hit by pitch (HBP) + sacrifice fly ( SF)

Slugging percentage (SLG) calculation formula

Slugging percentage is calculated by the number of bases advanced per at-bat. Batters who hit a lot of home runs and doubles have slugging percentages. Your batting average will be higher.

On-base percentage (OBP) = (number of singles + 2 x doubles + 3 x triples + 4 x home runs) / number of at-bats (AB)

Example of OPS calculation (for Ohtani) )

Shohei Otani 2024 season data

• At bats (AB): 636
• Hits (H): 197
< li>Doubles (2B): 38
• Triple bases (3B): 7
• Home runs (HR): 54
• Walks (BB): 81
>
• Hit by pitch (HBP): 6
• Sacrifice flies (SF): 5

Calculating On-Base Percentage (OBP)

OBP = (197+81+6)/(636+81+6+5) = 0.390

Calculating slugging percentage (SLG)

SLG = 98 + (2 x 38) + (3 x 7) + (4 x 54) / 636 = 0.646

Calculating OPS

OPS = OBP: 0.390 + SLG: 0.646 = 1.036

< p>OPS CORE is a new indicator created to analyze OPS (On-base Plus Slugging), an indicator used to evaluate baseball batting performance, in more detail.

OPS is While OPS CORE is a simple sum of a batter's on-base ability (OBP) and slugging ability (SLG), OPS CORE adjusts each component of OPS to accurately measure the batter's contribution. It takes into account the influence of leagues and stadiums.

Features of OPS CORE

Comparison with league average

OPS CORE is a ratio of 100 for the league average. It is calculated as:

If OPS CORE is over 100, it means that the batter's performance is above the league average.

Environmental Adjustment

OPS CORE takes into account the hitting environment of the entire league and the characteristics of each stadium (whether it is favorable for hitters or pitchers).

For example, OPS tends to be high in stadiums where home runs are more likely to be hit, but OPS CORE corrects this bias.

Intuitive interpretation

The OPS CORE value helps you intuitively understand the "superiority or inferiority of a hitter relative to the entire league."

OPS CORE formula

OPS CORE = Player's OPS / League average OPS
