Barrel mlb意思

"Barrel" in the context of Major League Baseball (MLB) refers to a statistic that measures the quality of contact made by a batter on a hit. The term "barrel" was introduced by MLB's Statcast system, which uses advanced tracking technology to analyze the flight of the ball and the exit velocity of batted balls.

A batted ball is considered a "barrel" when it meets certain criteria for exit velocity and launch angle that are optimized for a home run or extra-base hit. The exact criteria can change over time as the league adjusts the definition, but generally, a barrel is a batted ball with an exit velocity of at least 98 mph and a launch angle between 26 and 30 degrees. These parameters are designed to capture the most dangerous and productive batted balls.

The Barrel statistic is useful for evaluating hitters because it provides a measure of how often a batter hits the ball with the ideal combination of speed and trajectory to produce a long hit. It is considered a more advanced metric than traditional statistics like batting average, as it takes into account the quality of contact rather than just the outcome of the play.

In summary, when you see "barrel" in the context of MLB statistics, it refers to a specific type of hit that is likely to result in a home run or extra-base hit, as determined by Statcast's advanced tracking data.
