Base runs (BsR) is a baseball statistic invented by sabermetrician David Smyth to estimate the number of runs a team "should have" scored given their component offensive statistics, as well as the number of runs a hitter or pitcher creates or allows.
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.
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.
This might not be readily apparent: a Major League Baseball player's slugging percentage is almost always less than 1 because a majority of at bats result in either 0 or 1 base. The stat awards a double twice the value of a single, a triple three times the value, and a home run four times. [ 2 ]
Win Shares is a 2002 book about baseball written by Bill James and Jim Henzler. The book explains how to apply the concept of sabermetrics to assess the impact of player performance in a combination of several areas, including offensive, defensive, and pitching on their team's overall performance.
In Major League Baseball (MLB), .300 is considered an average BABIP. [2] Various factors can impact BABIP, such as a player's home ballpark; [3] for batters, being speedy enough to reach base on infield hits; [3] or, for pitchers, the quality of their team's defense. [4]
An example is baseball at the Summer Olympics, where if teams in pool play finish with identical records, run differential is used to determine which team advances to the knockout stage. [2] The 1956 Claxton Shield tournament, held in Australia, included an instance of a team attempting to manipulate the run differential in order to advance. [3 ...
In baseball, isolated power or ISO is a sabermetric computation used to measure a batter's raw power. One formula is slugging percentage minus batting average . I S O = S L G − A V G {\displaystyle ISO=SLG-AVG}
