Before Boog Powell at first base for the Orioles was Diamond Jim Gentile. He had a monster year in 1961 with 46 home runs and 141 RBIs. That was the year the M&M Boys, Mantle and Maris chased Babe Ruth's home run record for a single season which was the iconic number 60. Maris hit 61, Mantle 54 and Jim Gentile came in tied for third with Harmon "the Killer" Killebrew at 46. I think he was called Diamond Jim because he was noted for hitting grand slam home runs. Gentile was with the Orioles for only a few years. He was a journey man who played for several teams but his most memorable years were with the O's. Jim Gentile is a name not much recalled today but in his prime he was a slugger.
