Tigers Run Participation Leaders Since 1950

Following up on my previous post on run participation for all major league players since 1950, I will look at the Tigers today.   As a reminder, a player can participate in his teams' runs in three ways:

• Runs Scored (RS)

• Runs Batted In (RBI)

• Runs Assisted (RAS)

A Run Assisted is any contribution to a team run that does not result in a run scored or RBI for the batter.  The ways a player can get a Run Assisted (RAS) are described below:

• A batter advances a runner to either second or third with a hit, base on balls, hit batsmen, error, sacrifice bunt, or another kind of out.  If that runner then scores either during the same at bat or an ensuing at bat, the batter who advanced him is given a Run Assisted.

• A batter reaches base and is removed for a pinch runner or is replaced by another runner on a force out.  If the new runner then scores, the batter who originally reached base is given a Run Assisted. 

A player gets credit for a Run Participated In (RPI) if he either scores, drives in or assists a run.  There is no double counting for home runs so the formula is RPI = RS + RBI + RAS - HR

Table 1 presents the Tigers RPI leaders since 1950, the first complete year of Retrosheet data (required in order to calculated RAS).  Hall-of-Fame outfielder Al Kaline is the leader with 3,777 RPI followed by the dynamic duo of Lou Whitaker (2,998) and Alan Trammell (2,853).  Current slugger Miguel Cabrera figures to move up the list quickly.  He is currently 19th with 1,181, but if he keep up the same pace, he'll move into the top five in just three more years.

Runs Participated In is a counting statistic which is influenced greatly by length of career, so it's good to also have a rate measure.  One such metric is Runs Participated In Percentage (RPI%) which is the percentage of a teams' total runs in which a player participated.  For example, Tigers slugger Miguel Cabrera participated in 253 runs out of 726 total runs for the Tigers in 2012, so he had a 34.8% RPI%.  The RPI% statistic might tell us how much a team relied on a player to score runs.  As such, some fans might find it useful in MVP voting.  The limitation of course is that a player may benefit from having less productive teammates surrounding him in the order. 

Over the course of a career, you can average a player's annual RPI%'s to arrive at a career RPI%.  The RPI% leaders since 1950 among Tigers with at least 2,000 PA are listed in Table 2 below.  Cabrera is the leader averaging 30.9% in his five years in Detroit.  He is followed by outfielders Rocky Colavito (28.9) and Steve Kemp (28.2).
