Boston fans were left with a conundrum: Do you cheer for an opposing player if his grandfather is Carl Yastrzemski?

San Francisco Giants rookie Mike Yastrzemski homered in his first game at Boston's Fenway Park, where his grandfather Carl, the Red Sox icon, played for 23 seasons of his Hall of Fame career.

The last time anyone with the last name Yastrzemski homered at Fenway Park before Tuesday night was July 31, 1983, when Carl Yastrzemski did it for the Boston Red Sox against the Milwaukee Brewers.
