50 Years of Free Agency: How Baseball's Biggest Gamble Changed Everything
Baseball just hit a milestone that nobody really throws a party for, but absolutely should. Free agency turned 50 years old, and that means half a century of teams dropping massive money on players, some of whom became legends and others who became cautionary tales. So what better time to look back at the best and worst bets in MLB history?
The Beginning: Andy Messersmith Changed the Game
Here's the thing: there's no universal agreement on who actually started free agency. Some people point to Catfish Hunter, who won free agency on Dec. 16, 1974, and then signed a five-year, $3.2 million deal with the Yankees. That was huge money at the time. But Hunter's case? It was kind of a fluke, pulled off through legal maneuvering by Hunter and Marvin Miller's players' union related to a contract clause in his Athletics deal with Charlie Finley. It wasn't really the blueprint for what free agency would become.

On Dec. 23, 1975, arbitrator Peter Seitz made a historic decision that challenged the reserve clause, which had bound players to their teams for life. The appeal upheld that decision on Feb. 3, 1976, and suddenly Messersmith and fellow pitcher Dave McNally were granted free agency on March 16, 1976. McNally didn't actually want to keep playing, but Messersmith did. He signed the first true free agent deal: a three-year, $1 million contract with the Braves on April 10, 1976, moving from the Dodgers. Exactly 50 years ago today, if you're counting.
The Legacy: 8,340 Deals and Counting
Since Messersmith signed that first deal, teams have evaluated 8,340 free agent contracts. Some of them were steals. Others were absolute disasters. The debate over the greatest free agent signings of all time? That's centered on two names: San Francisco Giants slugger Barry Bonds and Atlanta Braves ace Greg Maddux. Those are the gold standard for what a free agent deal should look like.
Today's Mariners didn't shy away from their own free agent decisions, and a 6-2 win over Houston shows the team is building something worth watching early in the season.
