Run Shares: measuring offensive value in a team context

While there can be many ways to measure a position player’s offensive value, one method could be to evaluate the proportion of his team’s runs that are attributable to his own offensive contributions, a quantity that might be described as “Run Share”. That approach identifies these players as most valuable to their teams in 2013.

Those selections were based on FanGraphs‘ version of Runs Created (wRC), represented as a proportion of the actual runs that the player’s team scored. After the jump, more on Run Shares as a measure of offensive value.

As neither Trout’s Angels nor Goldschmidt’s D-Backs were serious contenders in 2013, a valid complaint about this method could be that a player’s contribution to a losing season is largely irrelevant in that the team still lost. The rebuttal would be that a player can only work within his own context. If he’s on a lousy team, even his most herculean effort will not make his team a winner. Nonetheless, the contribution a player makes to his team’s success (however modest that success may be) ought to be recognized, and this is one way to do it.

Here are the league leaders in Run Share for each season since 1901 (only seasons played for a single team are considered). First for the AL.

Cool beans, Doug. A question: Is the wRC formula team-dependent? The Bill James Runs Created formula, as I understood it, was meant to be mostly independent of team performance. I ask because, while most of these Run Share leaders are truly great seasons, a few are just good years for horrible offenses, e.g.: — Red Murray, 1908: 77 Runs Created (B-R formula) for a Cardinals team that scored 2.42 R/G. Murray was 4th in NL RC; Wagner led with 126. — Amos Strunk, 1916: 85 RC for an A’s team that scored 2.90 R/G. Strunk was 6th in AL RC;… Read more »
