NEW YORK — Major League Baseball owners gave the go-ahead Monday to making a proposal to the players’ union that could lead to the coronavirus-delayed season starting around the Fourth of July weekend in ballparks without fans, a plan that envisioned expanding the designated hitter to the National League for 2020.

Spring training would start in early to mid-June, a person familiar with the decision told The Associated Press. The person spoke on condition of anonymity because details of the plan were not announced.

MLB officials are slated to make a presentation to the union on Tuesday. An agreement with the players’ association is needed, and talks are expected to be difficult — especially over a proposal for a revenue split that would be unprecedented for baseball.

Each team would play about 82 regular-season games: against opponents in its own division plus interleague matchups limited to AL East vs. NL East, AL Central vs. NL Central and AL West vs. NL West.

Teams would prefer to play at their regular-season ballparks but would switch to spring training stadiums or neutral sites if medical and government approvals can’t be obtained for games at home. Toronto might have to play home games in Dunedin, Florida.

The All-Star Game, scheduled for Dodger Stadium in Los Angeles on July 14, likely would be called off.

Rosters Would Be Expanded From 26 to Around 30

Teams will propose that players receive the percentage of their 2020 salaries based on a 50-50 split of revenues MLB receives during the regular-season and postseason, which likely will be among the most contentious aspects of the proposal during negotiations with the players’ association.

That proposal would take into account fans being able to return to ballparks at some point, perhaps with a small percentage of seats sold at first and then gradually increasing.

Baseball players have refused to consider even the frameworks for the type of revenue splits that have been agreed to by unions in the NFL, NBA and NHL. The last attempt by baseball owners to gain a salary cap with a revenue split led to a 7 1/2-month strike in 1994-95 that wiped out the World Series for the first time in 90 years.

Rosters would be expanded from 26 to around 30. With minor leagues shuttered, there likely will be the addition of about 20 players per club akin to the NFL’s practice squad.

Players and teams agreed to a deal on March 26 that called for each player to receive only a portion of salary, determined by what percentage of a 162-game schedule is played. As part of that deal, if no season is played each player would receive 2020 service time matching what the player earned in 2019.

But that deal is contingent there being no restrictions on mass gatherings at the federal, state, city and local level; no relevant travel restrictions in the U.S. and Canada; and Commissioner Rob Manfred after consulting the union and medical expects, determines there is no risk to playing in front of fans at regular-season ballparks.

Players Accrue Salaries for the Regular Season Only

Players and teams committed to “discuss in good faith the economic feasibility of playing games in the absence of spectators or at appropriate neutral sites.” Manfred has said about 40% of MLB revenue is tied to gate, including concessions, parking, ballpark advertising, luxury suites and programs.

Union officials and players have cited the March 26 agreement as setting economic terms and say they have no inclination for additional cuts. Players are more interested in medical protocols and testing designed to protect them from and detect the new coronavirus. The proposal will detail the plan for dealing with players and staff who test positive.

Because players accrue salaries for the regular season only and not for spring training or the postseason, the union may counter by asking for more regular-season games during negotiations that could significantly alter or possibly even scuttle the restart plan.

The DH was adopted by the American League for the 1973 season but has been resisted by National League owners. The players’ union has favored it because it would create more jobs for high-paying hitters in their 30s, by MLB has looked at it as an economic issue.

Money, however, has disappeared as an issue at this stage for 2020 because nearly all veteran players have agreed to contracts. Yasiel Puig is the most notable exception.
