In 1961, Carl Yastrzemski made his Major League debut with the Boston Red Sox as the heir apparent to the legendary Ted Williams in left field. For 23 years, Yastrzemski proudly wore his famous "#8" for the Red Sox, with his extraordinary batting style and his unmatched skill in patrolling the grounds in front of the Green Monster. In the Red Sox' 1967 "Impossible Dream" season, he won the American League Triple Crown and was named the A.L.'s Most Valuable Player. "Yaz" was elected into the Baseball Hall of Fame in 1989. Carl Yastrzemski signed this official MLB baseball. A Steiner Sports Certificate of Authenticity is included.
