Mike Fast looks at the catcher inference leaders (batters, catchers, and even pitchers) since 2007 (subscription required). Carl Crawford, who reached base last night via catcher interference on Welington Castillo, leads the way. The top 15 batters in catcher interference have accounted for 60% of all interference calls (including playoffs and spring training) since 2007. Crawford has 14 and the next highest is 9. 15th on the list is Andres Torres who has never had a catcher interference call in the regular season or postseason, but has had 2 in spring training.
