PHILADELPHIA — Discussions about major leaguers playing in the 2028 Los Angeles Olympics baseball tournament are in the early stages, with players accustomed to top hotels seeking assurances of quality accommodations.

Major League Baseball has envisioned an extended 11-day All-Star break in two years. The last regular-season games before the break would be on July 9, followed by the All-Star Game on July 11, likely at San Francisco, and the Olympic tournament at Dodger Stadium from July 13-19. The season would resume on July 21.

“In general, our players want to play in the Olympics. They’re patriotic, and for them it’s a special opportunity, and we want them to have that opportunity,” union head Bruce Meyer said Tuesday ahead of the All-Star Game. “Having said that, we want to make sure that they have things like travel and accommodations, and things that they deserve based on who they are.”

Five entities are involved in the negotiations: Major League Baseball, the players’ association, the International Olympic Committee, the LA28 local organizing committee and the World Baseball Softball Confederation.

Meyer characterized discussions as early.

“We’re focused on player quality of life,” Meyer said.

The United States qualified automatically as host, and the Dominican Republic and Venezuela earned berths based on their finish in this year’s World Baseball Classic. Asia and Europe/Oceania will each have one spot, and the sixth nation will be determined during a final qualifying tournament.

“We went down the road on LA 2028 because we saw it as a unique opportunity to market the sport with our very, very best players,” MLB Commissioner Rob Manfred said. “It is a disruptive undertaking for us. Put money to one side, you’re disrupting your entire season, and if we’re going to undertake that effort, we want our very best out there so that people see how great our game really is.”

MLB wants player participation in the All-Star Game to be mandatory for those chosen, as well as for those picked for future All-Star Games.

A player not on the injured list who is selected for the Olympics but declines to participate in the All-Star Game would be subject to a fine and/or suspension. Those players would also be ineligible to play for the first 14 days when the season resumes after the Olympics, according to a proposal from the commissioner’s office to the players’ union, obtained by The Los Angeles Times.

San Francisco last hosted the Midsummer Classic in 2007 at what was then at AT&T Park (now Oracle Park). The game was also in San Francisco at Candlestick Park in 1961 and 1984.
