7. Nolan Arenado – Colorado Rockies, Major League Baseball:
This deal rates as one of the newer huge deals on the list. Arenado signed with the Rockies for 8 years and $260,000,000 before the 2019 season. The contract extension averages $32,500,000 a year and $200,617.28 a game.
The jury is still out on this particular contract extension as the player is still in the first year of it.
