Carl Yastrzemski 5

When my dad took me to Fenway for the first time(a doubleheader vs. the new Los Angeles Angels), Yaz was the rookie from Long Island replacing Ted Williams in left field.He won everyone over and in 1967, had a season like no other. He always got a hit when needed and played the wall (commercially known as the Green Monster)perfectly. From that point on, the Red Sox stopped being a doormat and become a contender every season. Yaz was the difference. By the way, you spelled his name wrong.
