Buster Posey
Not many athletes are able to represent one team for their entire professional careers, but Buster Posey is among the few who can. After making his Major League debut for the San Francisco Giants in 2009, he stayed with them for twelve seasons, establishing himself as one of the most prolific catchers in the game.
He won himself almost every award there is, being named Rookie of the Year in 2010 and the National League’s Most Valuable Player in 2012. In 2021, he surprisingly retired early at the age of 34 and joined the Giants’ ownership group, having fulfilled his potential as a player.
