George Kenneth Griffey Jr., nicknamed "Junior" and "the Kid", is an American former professional baseball outfielder who played 22 years in Major League Baseball (MLB). He spent most of his career with the Seattle Mariners and Cincinnati Reds, along with a short stint with the Chicago White Sox. A member of the Baseball Hall of Fame, the first overall pick in the 1987 draft, and a 13-time All-Star, Griffey is one of the most prolific home run hitters in baseball history; his 630 home runs rank as the seventh-most in MLB history. Griffey was also an exceptional defender and won 10 Gold Glove Awards in center field. He is tied for the record of most consecutive games with a home run.

An outfielder is a person playing in one of the three defensive positions in baseball or softball, farthest from the batter. These defenders are the left fielder, the center fielder, and the right fielder. As an outfielder, their duty is to catch fly balls and ground balls then to return them to the infield for the out or before the runner advances, if there are any runners on the bases. As an outfielder, they normally play behind the six players located in the field. By convention, each of the nine defensive positions in baseball is numbered. The outfield positions are 7, 8 and 9. These numbers are shorthand designations useful in baseball scorekeeping and are not necessarily the same as the squad numbers worn on player uniforms.
