In Strat-O-Matic, outfielder errors result in the batter reaching second or third. What kind of errors do outfielders really make?
I looked at the 2,386 errors made in MLB 2005-2009. (From Retrosheet, natch.) That’s about one every five games. I divided them into the five categories shown in the chart below.
Only a quarter involve the batter reaching base on the error. The majority involve advancement of other baserunners, most after a hit.
A little more detail in the table below, which shows how many bases the batter advanced on the error.
An error that allows the batter to go to second on a single is, by far, the most common occurrence. The table hides a lot of detail, though, like the base situation and the advancement of those other runners.
