Keywords
💡Triple Slash Line
The Triple Slash Line is a fundamental baseball statistic that summarizes a hitter's performance. It consists of three components: batting average, on-base percentage, and slugging percentage. These stats provide a snapshot of a player's hitting abilities by indicating how often they get hits, get on base, and hit for power. For example, a player who 'slashed' .300/.400/.500 in 2021 would have a batting average of .300, an on-base percentage of .400, and a slugging percentage of .500.
💡Batting Average
Batting Average is a traditional baseball statistic that measures how often a player gets a hit. It is calculated by dividing the number of hits by the number of at-bats. While it is a foundational stat in baseball, it has limitations as it does not account for walks and treats all hits equally, regardless of their value. A good batting average is considered to be .300 or above, with .244 being average and less than .230 being poor.
💡On-Base Percentage (OBP)
On-Base Percentage (OBP) is a baseball statistic that measures how often a batter reaches base. It is calculated by adding hits, walks, and hit by pitches, then dividing by the sum of at-bats, walks, and hit by pitches. OBP is valuable because it includes walks and hit by pitches, which are often overlooked in batting average. An elite OBP is over .400, with .290 being average and below .290 being poor.
💡Slugging Percentage
Slugging Percentage is a measure of a player's power in baseball, indicating the total number of bases a player accumulates per at-bat. It differentiates between the types of hits (singles, doubles, triples, home runs) by assigning different values to each. A slugging percentage of .380 or below is considered poor, .411 is average, and .550 or above is excellent. Unlike OBP, slugging percentage only considers hits and not walks or hit by pitches.
💡OPS (On-Base Plus Slugging)
OPS, or On-Base Plus Slugging, is a composite baseball statistic that combines on-base percentage and slugging percentage to give a broad view of a hitter's offensive production. It is calculated by simply adding a player's OBP and slugging percentage. OPS is widely used because it provides a single number that reflects both a player's ability to get on base and their power. However, it treats slugging and on-base as equally important, which may not always be the case in reality.
💡Hitting Power
Hitting power in baseball refers to a player's ability to hit the ball hard and often, which is typically measured by their slugging percentage. It reflects the player's capacity to hit for extra bases, including doubles, triples, and home runs, and is a critical component of a player's offensive contribution to the team.
💡Walks
In baseball, a walk occurs when a batter receives four pitches outside the strike zone, allowing them to advance to first base without hitting the ball. Walks are an important part of a player's on-base percentage as they contribute to getting on base without the need for a hit, which is highlighted in the video as a valuable yet often undervalued aspect of the game.
💡Hit by Pitch
A hit by pitch in baseball happens when a batter is struck by the ball while in the batter's box and not attempting to swing at the pitch. This event allows the batter to reach first base, similar to a walk, and is included in the calculation of both on-base percentage and slugging percentage, reflecting a player's ability to avoid being struck and reach base safely.
💡Sacrifice Flies
A sacrifice fly in baseball is a play in which the batter hits the ball high and deep enough into the outfield to allow a runner on third base to tag up and score while the batter is thrown out at first base. This selfless act increases the team's score but does not count as a hit for the batter. It is included in the calculation of on-base percentage but not in slugging percentage.
💡Juan Soto
Juan Soto is a professional baseball player mentioned in the script as an example of an outstanding hitter. His 2021 slash line of .313/.465/.534 demonstrates his exceptional abilities in batting average, on-base percentage, and slugging percentage, which are key indicators of a hitter's performance.
💡Max Muncie
Max Muncie is another professional baseball player cited in the video as an example of a great hitter. His 2021 slash line of .249/.368/.527 shows his performance in terms of batting average, on-base percentage, and slugging percentage, which, while not as high as Juan Soto's, still indicates a strong offensive player.
Highlights

The video is the first in a series of occasional explainers on baseball statistics.

Today's topic focuses on the very basics of hitter stats, including the triple slash line and OPS.

The triple slash line is a basic summary of a hitter's abilities, consisting of three stats: batting average, on-base percentage, and slugging percentage.

Batting average, despite being flawed, is the foundational stat in baseball, calculated by dividing the number of hits by the number of at-bats.

A good batting average is categorized as poor (less than .230), average (.244 to .299), and excellent (.300 or above).

On-base percentage (OBP) measures how frequently a batter gets on base and is calculated by dividing hits, walks, and hit by pitches by at-bats, walks, hit by pitches, and sacrifice flies.

An elite on-base percentage is over .400, indicating the player gets on base 40% of the time.

Slugging percentage describes the total number of bases a player records per at-bat, focusing on power and differentiating the value of different hits.

The formula for slugging percentage is singles plus two times doubles, three times triples, and four times home runs, divided by the number of at-bats.

OPS, or on-base plus slugging, combines on-base percentage and slugging percentage to give a single number that represents a hitter's abilities.

An OPS close to or above 1 is considered excellent, with higher values indicating better hitting abilities.

Juan Soto of the Nationals had an outstanding 2021 with a slash line of .313/.465/.534, demonstrating exceptional hitting skills.

Max Muncie of the Dodgers was a great hitter in 2021 with a slash line of .249/.368/.527, showing a balance of getting on base and hitting for power.

An average hitter like Ozzie Albies from the Braves had a 2021 slash line of .259/.310/.488, illustrating a typical performance level.

A struggling hitter like Cole Tucker of the Pirates had a 2021 slash line of .222/.298/.342, indicating areas for improvement.

The video provides a rule of thumb for evaluating hitters using the numbers 300, 400, and 500, corresponding to batting average, on-base percentage, and slugging percentage.

The video concludes with an encouragement to learn these stats and their scales for accurately evaluating MLB hitters.
