Mike Trout Scores Lifetime Deal Worth Over $400Million.

Los Angeles Angels are closing in on a 12-year contract extension worth at least $430 million with outfielder Mike Trout, setting the all-time mark for both the largest contract and the greatest average annual contract value in baseball history.

According to Fan Graphs estimated market values based on wins above replacement , a player with Trouts 2018 production should have been worth about $79 million last season.

If Trout continues his recent pace, the Angels will basically be paying him half of what hed be worth on the open market over the next few seasons.

Even though no player in baseball history has posted more career WAR through their age-26 season than Trout,1 its probably safe to assume that Trout wont continue to be a 10-WAR-per-season machine throughout the entire life of this contract.
