This year we’ve heard plenty about Kevin Long’s Home Run Drill, an exercise that he uses to help hitters shorten their swings and generate more power. Today at the Star Ledger Brendan Prunty describes the history of the drill. It started when Long was a hitting coach in the Kansas City system, and he nearly scrapped it before one hitter experienced exceptional results. Now the Yankees are using it to their advantage, none more prominently than Robinson Cano. This is just another reason why Long will become the highest paid hitting coach in the league when he signs a new contract this off-season.
