Ken Griffey Jr was born to play baseball. The Hall of Famer is the son of Ken Griffey Sr., former MLB outfielder, mostly for the Cincinnati Reds' "Big Red Machine" and the New York Yankees. As a youngster, "Junior" used to hang out in the New York Yankee clubhouse with his father and even work in practice time on the Yankee Stadium field. Presented is a 1989 game used Ken Griffey Jr Seattle Mariners bat from Junior's rookie season. Junior broke into the Major Leagues in '89 as a 19-year-old center fielder for the Seattle Mariners. That season he hit 16 homers, with 61 RBIs, batting .264 with 16 stolen bases. In '89, he finished third in the '89 AL Rookie of the Year voting. In his 22 -year MLB career, Junior hit 630 home runs, the seventh most in MLB history. The 7-time Silver Slugger winner won 10 Gold Gloves and was a 13-time All-Star. His best overall season was in 1997, with Seattle, as he led in AL in homers (56), RBIs (147), and Slugging (.646), and batted .304. In 1990-91, the Griffeys played together on the same Seattle team. On Sept. 14, 1990, the Griffeys hit back-to-back home runs for Seattle against the California Angels, the first and only father and son duo to hit home runs back-to-back.
