In my first installment on fourth minor league options, which you can find here, I outlined the fourth option rule and made my case for why Cards’ 40-man roster infielder Edmundo Sosa should be eligible for a fourth minor league option for the 2020 season. In this piece, I will outline all the cases that I know of where the Cards have exercised a fourth option on a player. It takes a very narrow set of circumstances for a player to be eligible for such an option, and I know of only three prior cases in Cardinal history.
