The Atlanta Braves have been very aggressive under general manager Alex Anthopoulos in locking up its young players to long-term extensions. Since 2019, the organization has extended much of its core to team-friendly contracts, highlighted by the likes of Ronald Acuña, Ozzie Albies, Michael Harris, and Spencer Strider.
These types of contracts are a proverbial win-win for both the player and the team. They provide the players with generational wealth and security while giving the organization "cost-certainty" as they build out their roster in both the short and long term.
While the Braves didn't invent this strategy, they certainly made it popular. Grant McAuley discussed how some other teams in the Majors are starting to emulate them following the moves of the Arizona Diamondbacks and Washington Nationals.
