Jim Griffin

Jim Griffin is a lifelong baseball fan with experience writing for Yankee-specific blogs from 2010 through 2016. His first book, The New York Yankees All-Time All-Stars, was published in 2019 and soon after that he began his own Yankee blog, Jimmy Sez (https://jimmysezblog.blogspot.com/). An analyst by trade, he holds degrees in Mathematical Sciences (B.S.) and Applied Statistics (M.S.) from Villanova University where his master’s thesis was a study on New York Yankees offensive statistics since 1920. Accordingly, he makes liberal use of key performance metrics and statistical concepts to support his written material.
