"At one time, players' kids would get to Yankee Stadium early, to hang out before games. On this day, groups of boys were running around the Yankee clubhouse and playing on the field.But Billy Martin zeroed in on one of them. Martin sent a security guard into the dugout where a 13-year-old boy and his father – the Yankees star 1st baseman – were hanging out."Hey, George Steinbrenner doesn't want anybody in the dugout."The player complied, sending his son into the clubhouse. As the boy left, his dad motioned for him to "look at third base." It was Graig Nettles' son taking ground balls on the field. The Yankees star felt insulted. And his 13-year-old son took it to heart. This kid held a grudge against the Yankees for the next 30 years.His name? George Kenneth Griffey Jr."Come play for the Yankees, bro!""No," Junior shot back. "If the Yankees were the last team – if they were the only team that gave me a contract, I'd retire."
