Major League Baseball's owners are expected to send a new proposal to the players union on Friday that includes a season lasting between 70 and 75 games, sources told ESPN's Karl Ravech.

The owners' proposal would include a payment of somewhere between 80% and 85% of the players' prorated salary, which is a slight increase from the owners' last effort. This proposal also includes expanded playoffs and a share of the playoff pool for players.

This marks the third exchange of proposals between the two sides this week.

On Tuesday, sources told ESPN that the MLBPA offered an 89-game proposal that featured a full prorated share of salary and expanded playoffs.

MLB on Monday proposed a 76-game season that would cover up to 75% of players' prorated salaries. In that proposal, MLB also outlined the elimination of direct draft-pick compensation for free agents tagged with qualifying offers; teams losing top free agents would get a compensatory draft pick but those signing that free agent would not be penalized by having to give up a top pick. Sources told Ravech this provision remains in the owners' newest proposal.

If the sides are unable to agree to a deal, the league has the ability to implement a schedule of its desired length. It has focused recently on a potential 48-game season, sources told ESPN earlier this week.

Sources told Ravech on Friday that owners are looking to have a tighter window for the season to avoid starting then having to stop play.
