Jamie Moyer

Drawing on data from 1913 through 2002, Tom Tippett of Diamond Mind Baseball found that six of the top 35 pitchers in BABIP were knuckleballers. He observed that soft-tossing lefties such as Jamie Moyer (right) had low BABIPs despite low strikeout rates. In Moyer’s case, he made up for it with an exceptionally low walk rate. Successful pitchers with low strikeout rates and high BABIPs—Tommy John, for example—led Tippett to suggest further research on the ability of pitchers to induce double-play groundballs.
