Carl Michael Yastrzemski  nicknamed "Yaz," is a former American Major League Baseball player and member of the Baseball Hall of Fame. Yastrzemski played his entire 23-year career with the Boston Red Sox, primarily as a left fielder, with part of his later career played at first base and as a designated hitter. Yaz is an 18-time all-star, the possessor of seven Gold Gloves, a member of the 3000 hit club, and the first American League player in that club to also accumulate over 400 home runs. He is second on the all-time list for games played, and third for total at-bats. He is the Red Sox' all-time leader in career RBIs, runs, hits, singles, doubles, total bases, and games played, and is second on the team's list for home runs (in a Red Sox uniform) behind another Red Sox great, Ted Williams, his predecessor in left field. In 1967, Yastrzemski achieved a peak in his career, leading the Red Sox to the American League pennant for the first time in over two decades, in that season being voted the American League MVP, and being the last winner of the triple crown for batters in the major leagues.

Born August 22, 1939 his primary personality traits are ruled by the Chinese Zodiac elemental animal, the Earth Rabbit. Practical Earth combines with the emotional Rabbit to make this the most calculating Rabbit. He shrewdly determines the best way to secure the material resources he needs to lead a comfortable, refined life. He tends to prefer the home life and usually comes off being less social than other Rabbits. Nevertheless, he often wins the respect of those around him and is in general the most respected of the Rabbits.
