Taking it back to August 31st, 1990. Kingdome. Seattle, Washington. In the bottom of the 1st inning, newly acquired, 40 year old Ken Griffey Sr. laces a ball sharply back up the middle for a base hit in his first Mariner at bat. Up next, his son, Ken Griffey Jr. takes a page right out the old man’s playbook, and connects on a single of his own. Any guesses on the Kansas City Royals right hander who allowed the Father/Son back to back?
