The Free Agency Era: How the Reserve Clause Ended and Salaries Rose

By 4Baseball Staff · November 5, 2026 · 11 min read

How an arbitrator's ruling on Andy Messersmith in 1975 opened free agency, then the strikes, collusion cases and rising pay that shaped baseball until the eve of the 1994 strike, with season data from 1976 and 1985.

On December 23, 1975, an arbitrator named Peter Seitz issued a ruling that changed who had power in baseball. For almost a century the sport had run on the reserve clause, which let a club keep a player's rights year after year. Seitz decided that the clause bound a player for one additional season and no more, so a pitcher named Andy Messersmith, who had played out 1975 without signing a new contract, could become a free agent. Within a year the first free agents were choosing among bidders. Within two decades the average player was earning roughly a million dollars a year.

This article covers the stretch from that decision to the year before the 1994 strike. It is a story of three arguments that never fully ended: how much freedom players should have, how much clubs should be allowed to coordinate, and what the money was doing to the competition on the field. It uses the historical record for the season-level figures and sticks to events that are well documented. Contract values are given only where they are widely agreed, and the exact rules of any given year are best checked in the collective bargaining agreement of that year.

If you read only one thing about the era, make it this: free agency did not arrive in a single moment. It arrived in a ruling, a compromise, a strike, three collusion cases and a lockout, and each step has a separate lesson.

The reserve clause and the cases that failed first

Before 1976, a player's contract included a clause that renewed it for another season at the club's option. The clubs read it as perpetual; the players read it as a single year. A player who disliked his salary could sign, sit out or quit. Almost all of them signed. The Players Association, which had been led since 1966 by Marvin Miller, a former steelworkers' economist, spent its first years winning smaller things: a higher minimum salary, a better pension, an arbitration process for grievances, and in 1973 the right to salary arbitration for players with at least two years of service.

The first direct challenge was a lawsuit. Curt Flood, an outfielder for the St. Louis Cardinals, refused a trade to Philadelphia after the 1969 season and sued baseball. The Supreme Court ruled against him in 1972, by a vote of 5 to 3, leaning on its older decisions that treated baseball as exempt from the antitrust laws. Flood lost, and the union was left looking for another route. It found one in 1974, when the Athletics owner Charlie Finley failed to make a payment called for in Catfish Hunter's contract, and an arbitrator (Peter Seitz, the same man who would rule on Messersmith) declared Hunter a free agent. Hunter signed a record contract with the Yankees. He had reached the market through a breach of contract rather than a rule change, but he showed what the market might do.

December 1975: the Messersmith and McNally grievance

The test case was built carefully. Andy Messersmith, a pitcher for the Los Angeles Dodgers, and Dave McNally, who had pitched for Baltimore and was by then with Montreal, did not sign contracts for the 1975 season. The clubs then renewed them under the reserve clause, as the clauses allowed, and the Players Association filed a grievance arguing that the renewal covered only one year, so a player who played that year unsigned owed the club nothing more.

The arbitration panel had three members: Seitz as the neutral chairman, one owner representative and one union representative. Seitz sided with the players. The owners fired him immediately, as they had the contractual right to do, and went to court. A federal judge and the appeals court upheld the ruling in 1976. The owners also locked the players out of spring training that March, and Commissioner Bowie Kuhn ordered the camps opened after a few weeks. By the summer the two sides had a four-year agreement that kept most of what Seitz had given the players and added limits.

The central point of the compromise was a service-time rule. A player could become a free agent only after six years in the major leagues, a threshold that has stayed in the sport in some form ever since. Players with less service were still bound by the reserve system for their first six years, which meant that the owners kept the right to control young players cheaply, and the union conceded that point in exchange for the right to a market for the rest.

The first re-entry draft and the new market

In November 1976 baseball held its first re-entry draft, a mechanism by which clubs picked the right to negotiate with the players who had become free agents. About two dozen players were in the pool. The point of the draft was to limit how many clubs could bid for each player, a compromise that protected the owners from a free-for-all. It was dropped in later agreements.

The class was small but loud. Reggie Jackson, a 1973 MVP who had spent one year with Baltimore, signed with the Yankees for five years. The deal was reported at a little under three million dollars, an enormous number then; his career is described in the Reggie Jackson profile. Other stars moved too, and the newspapers filled with stories about contracts that were larger than anything in the sport's past. One of those contracts became a cautionary tale: Wayne Garland, an Orioles pitcher who had won 20 games in 1976, signed a ten-year deal with Cleveland and then hurt his arm. Teams learned quickly that the long contract carried a risk the one-year contract had not.

Players who stayed with their clubs also benefited. Salary arbitration, in which a neutral arbitrator picks between the player's figure and the club's after a hearing, meant that a player with a few years of service (two in 1973, later three, with exceptions) could make a case for a raise even if he could not leave. Arbitration and free agency together changed what a player was paid at each stage of a career: the first years at something near the minimum, the middle years by arbitration, and after six years whatever the market would give.

What the numbers looked like: 1976 and 1985

The historical record gives a way to compare the first season of free agency with one nine years later. The comparison is not a controlled experiment, since two expansion teams (Seattle and Toronto) joined in 1977 and many other things changed, but it captures the shape of the era.

Attendance per team rose by about 38 percent over the nine years, and the game's scoring rose with it: home runs per team-game went from 0.58 to 0.86, an increase of nearly half. Nobody can say how much of that growth belongs to free agency, since the sport grew for other reasons too. What the figures do show is that the new freedom of movement did not hurt the product on the field, at least by the measures fans noticed.

The pitching leaders show how the game moved. In 1976 Mark Fidrych, the American League Rookie of the Year, led his league with a 2.34 ERA, and Nolan Ryan struck out 327 batters. In 1985 Dwight Gooden won 24 games, struck out 268 and posted a 1.53 ERA in the National League, while the American League's best ERA was Dave Stieb's 2.48. Run scoring rose by about 8 percent over the nine years, from 3.99 to 4.33 per team-game, so the best pitchers were working against a livelier league.

1981: the strike over compensation

The 1976 agreement left one big question open: what should a club that lost a free agent receive in return? The owners wanted real compensation, meaning an actual major-league player, and the union objected that this would suppress the market, since a club would not sign a free agent if it had to give up a player. The sides deferred the question to a joint committee in 1980, the committee did not solve it, and on June 12, 1981, the players went on strike. The walkout lasted 50 days and wiped out roughly a third of the schedule.

When play resumed, the owners and the commissioner settled on an expedient: the season would be split into two halves, with the first-half leader in each division meeting the second-half leader in a division series. The format raised the kind of question that tiebreaking rules exist to settle (see how MLB tiebreakers work), and it produced an oddity: the Cardinals and the Reds had the best overall records in their National League divisions and missed the playoffs, because neither won a half. The compensation dispute was settled with a pool of players rather than direct payment, a clumsy compromise that was replaced in later agreements.

The 1981 strike left bitterness on both sides. Attendance recovered, though, and the strike did not harm the sport's growth in the years that followed. A shorter strike took place in August 1985, lasting two days, before the sides agreed to a new contract.

Collusion, 1985 to 1987

The third argument, about coordination, came to a head in the mid-1980s. After the 1985 season, a larger share of free agents than usual received no offers from clubs other than their own, or received offers only when it was too late to matter. Stars who would have drawn bids in earlier years returned to their old teams for modest raises or sat unsigned into the spring. The union believed that the owners had agreed among themselves not to bid, which the basic agreement prohibited.

Several stories of the time illustrate it. In 1987, outfielder Andre Dawson, who wanted to play on grass in Chicago, offered the Cubs a blank contract and let them fill in the figure; the Cubs wrote in a salary that was modest for a player of his record, and Dawson won the National League MVP award that year. The example is often told as an illustration of how thin the market was, although it is better understood as a player's own gamble.

The union filed grievances, and arbitrators ruled in the players' favor three times: Thomas Roberts in 1987 for the 1985 free-agent class, George Nicolau in 1988 for the 1986 class, and Nicolau again in 1990 for the 1987 class. The arbitrators found that the clubs had acted in concert in violation of the agreement. In late 1990 the sides settled the claims, with the owners paying the players a sum reported at $280 million, and some players were granted free agency again. The episode left a lasting legacy of mutual distrust. It also set up the later disputes: the 1990 spring-training lockout, and the confrontations that led to the strike of 1994.

Competitive balance, and the argument the owners lost

When free agency started, owners predicted it would ruin competitive balance by letting the richest clubs buy every star. The record of the era does not support that fear. Between 1979 and 1991, no team won back-to-back World Series. The champions across 1976 to 1993 included the Reds, the Yankees (twice), the Pirates, the Phillies, the Dodgers (twice), the Cardinals, the Orioles, the Tigers, the Royals, the Mets, the Twins (twice), the Athletics, the Reds again, and the Toronto Blue Jays (twice). That is a wide spread across big and small markets.

One reason is that a free agent is a single player, and even a very good player is only a fraction of a team. Another is that a club that overpays tends to pay for a player's past rather than his future; the Garland contract is the classic example. A third is that teams developed ways to use the system: trading a player in his final year before free agency, and building a core through the amateur draft, which had been operating since 1965 and assigned the right to sign amateur players in reverse order of the standings. The draft was the counterweight to free agency. It kept the first six years of a player's career cheap and controlled, and made it possible for a small-market club to win by finding talent rather than buying it.

Still, the market affected how teams were run. The growth of player agents, the use of long-term contracts and the arrival of arbitration cases as an annual ritual all date from this period. For how the front office eventually responded to a market in which salary and performance were tied together, see the analytics era from Moneyball to the front office.

1990 to 1993: the road to 1994

The final years of the era were tense. The owners locked out the players in spring training of 1990, a dispute that was settled after about a month. By the early 1990s the average salary was approaching or passing a million dollars, a figure that would have been unimaginable in 1975, and owners complained that revenue was unevenly distributed between large and small markets. Commissioner Fay Vincent, who had angered several owners, was pushed out in 1992, and Bud Selig, an owner from Milwaukee, took over as acting commissioner. By 1994 the owners were pushing a plan that tied revenue sharing to a salary cap, a proposal the union rejected.

The outcome was the strike that began on August 12, 1994, which cancelled the rest of that season and the World Series, the subject of the article on the 1994 strike. The home run records that followed in the late 1990s, discussed in the home run surge article, arrived in a sport that had just rebuilt its labor relations from the ground up.

Common questions

Who was the first free agent? The answer depends on the definition. Catfish Hunter was freed from his contract by an arbitrator in 1974 and signed with the Yankees. Andy Messersmith and Dave McNally were the players in the 1975 grievance that opened general free agency. The first re-entry draft, in November 1976, was the first time a large group of players reached the market.

How many years until a player becomes a free agent? Six years of major-league service under the 1976 agreement, and the six-year threshold has remained part of the system through 2025. Check the current collective bargaining agreement for details about how service time is counted.

What was collusion? An agreement, spoken or implied, among clubs not to bid for free agents. The basic agreement prohibited it, and arbitrators found three times that it had occurred in the mid-1980s.

Did free agency hurt attendance? The historical data says no: attendance per team grew about 38 percent between 1976 and 1985. Whether free agency deserves any of the credit is harder to say, since other things changed over the same years.

Why did the owners accept the system? They did not accept it voluntarily; arbitration and the courts forced the change. After 1976, they bargained over how to limit its effect, which is why the history of the following two decades is a list of disputes.
