  2. PITCHf/x - Wikipedia

    en.wikipedia.org/wiki/PITCHf/x

    PITCHf/x is a system using three permanently mounted cameras in the stadium to track the speed and location of a pitched baseball from the pitcher's mound to home plate with an accuracy of better than one mile per hour and one inch. With PITCHf/x, statistics such as the pitcher with the fastest fastball, or the pitcher with the sharpest ...

  3. Statcast - Wikipedia

    en.wikipedia.org/wiki/Statcast

    Trevor Story's 518-foot home run of July 12th, 2021, is the longest measured by Statcast.. The PITCHf/x system, first used in the 2006 MLB postseason, is a camera-based system that can measure the trajectory, speed, spin, break, and location of a pitched ball.

  4. Exit velocity - Wikipedia

    en.wikipedia.org/wiki/Exit_velocity

    In baseball statistics, exit velocity (EV) is the estimated speed at which a batted ball is travelling as it is coming off the player's bat. Batters generally aim for a higher exit velocity in order to give opposing fielders less time to react and attempt a defensive play [ citation needed ] ; however, many batters are still able to accrue hits ...

  5. Magnus effect - Wikipedia

    en.wikipedia.org/wiki/Magnus_effect

    In baseball, pitchers often impart different spins on the ball, causing it to curve in the desired direction due to the Magnus effect. The PITCHf/x system measures the change in trajectory caused by Magnus in all pitches thrown in Major League Baseball. [33]

  6. Slugging percentage - Wikipedia

    en.wikipedia.org/wiki/Slugging_percentage

    In baseball statistics, slugging percentage (SLG) is a measure of the batting productivity of a hitter. It is calculated as total bases divided by at-bats , through the following formula, where AB is the number of at-bats for a given player, and 1B , 2B , 3B , and HR are the number of singles , doubles , triples , and home runs , respectively:

  7. Runs created - Wikipedia

    en.wikipedia.org/wiki/Runs_created

    In the most basic runs created formula: = (+) + where H is hits, BB is base on balls, TB is total bases and AB is at-bats.. This can also be expressed as = = where OBP is on-base percentage, SLG is slugging average, AB is at-bats and TB is total bases, however OBP includes the hit-by-pitch while the previous RC formula does not.

  8. Extrapolated Runs - Wikipedia

    en.wikipedia.org/wiki/Extrapolated_Runs

    Extrapolated Runs (XR) is a baseball statistic invented by sabermetrician Jim Furtado to estimate the number of runs a hitter contributes to his team. XR measures essentially the same thing as Bill James' Runs Created, but it is a linear weights formula that assigns a run value to each event, rather than a multiplicative formula like James' creation.

  9. Eephus pitch - Wikipedia

    en.wikipedia.org/wiki/Eephus_pitch

    The eephus pitch is thrown overhand like most pitches, but is characterized by an unusual, high-arcing trajectory. [2] [3] The corresponding slow velocity bears more resemblance to a slow-pitch softball delivery than to a traditional baseball pitch. It is considered a trick pitch because, in comparison to normal baseball pitches, which run from ...
