Ron Santo: 9 selections
Perhaps the greatest third baseman in Chicago Cubs history is Ron Santo, who has the highest Wins Above Replacement (72.1) of any player in the team's illustrious history. That is expected for Cap Anson but he played in the late 1800s when the game was drastically different so Ron Santo takes the honor in my eyes.
Despite his 9 All-Star selections, 5 gold gloves and his post-playing career dedication as a color broadcaster, Santo did not see himself get inducted into the Hall of Fame and he passed away in 2010 at the age of 70 from cancer and diabetes complications. The following year a statue of Santo was presented at Wrigley Field and he was posthumously inducted into the Baseball Hall of Fame in 2012.
