In 1960, at the age of 19, Yastrzemski would be signed by the Boston Red Sox for $108,000. He would spend the first year of his career in the minor leagues. After only one year, Yaz would be called up to the Majors, replacing the recently retired Ted Williams at left field. As previously stated, Yaz would spend his entire 18 year career in Boston. Although he did not end up becoming like the legend of Williams, he certainly hammered down a statement as one of the best players in his era. Defensively, Yastrzemski would become one of the best defenseman winning seven gold glove awards. Not only was that a difficult milestone, but also the fact of playing in front of the giant 37-foot wall, the Green Monster, did not make it any easier.

Although his defensive abilities were outstanding, Yaz was remembered mostly for his incredible hitting ability. He would be a force to be reckoned with, with his batting stance, in which he would hold his bat high, to provide him with a powerful swing. Most pitchers “tried everything on Yaz and nothing works. The only thing you can do against him is pitch him tight and hope” (Elston Howard). For most pitchers, there was no hope, as Yaz would win three American League Batting Championships. In 1967, he would win the Triple Crown and MVP, leading the American League in batting average (.326), RBIs (121), and home runs (44), proving again that he was one of the best. Ending his career in 1983, he would be inducted in the Hall of Fame in his first ballot in 1989.
