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.
Base runs will sometimes project many more than three runners left on base per inning, despite the fact that three is the upper limit. For example, if walks have a B coefficient of .1, an inning with 10 walks and three outs will yield an estimate of 10*1/(1+3) = 2.5 runs, meaning that 7.5 runners must have been stranded.
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.
Runs produced is a baseball statistic that can help estimate the number of runs a hitter contributes to his team. The formula adds together the player's runs and run batted in, and then subtracts the player's home runs.
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 ...
The leading team, in terms of games behind, is the team with the best won–loss difference. This is not always the team with the most wins. For example, a team with an 80–70 record (10 more wins than losses) would be one game behind a team with a 79–67 record (12 more wins than losses).
His total number of bases (388) divided by his total at-bats (458) is .847, which constitutes his slugging percentage for the season. [ 5 ] Ruth's 1920 figure set a record in Major League Baseball (MLB), which stood until 2001 when Barry Bonds achieved 411 bases in 476 at-bats for a slugging percentage of .863.
It considers statistics for baseball players, in the context of their team and in a sabermetric way, and assigns a single number to each player for his contributions for the year. A win share represents one-third of a team win, by definition. [2] If a team wins 80 games in a season, then its players will share 240 win shares.
