Gregg Zaun's run production stat leads to creation of ZARP
There's a new stat for data enthusiasts and old-school fans alike: It's called ZARP and, unlike FIP, WAR, and other hard-to-calculate acronyms, it's incredibly easy to understand.
Prior to Game 1 of the American League Championship Series on Friday, Sportsnet analyst and former MLB catcher Gregg Zaun revealed his own way of evaluating a player's run production, and the formula goes like this: Runs scored + RBI - home runs divided by games played. Needless to say, Zaun's simplified approach caught the attention of saber-friendly scholars on Twitter.
The formula reached the fine folks at Baseball Reference, the indispensable website famous for its massive database of stats. Zaun's easy-to-use formula was quickly converted into a sophisticated-sounding acronym ZARP (Zaun Run Production), and the rest is baseball history.
Fun fact: Seventeen of the top 20 leaders in ZARP played most of their careers during the 19th century.
