The Major League Baseball Players Association is preparing its rebuttal.
After receiving MLB's economic proposal Tuesday, the union plans to send its response by the end of the week, sources told ESPN's Jeff Passan.
Part of the union's proposal is expected to include a schedule that exceeds 82 games and requires players to be paid their full prorated salaries, sources told Ken Rosenthal and Evan Drellich of The Athletic.
The rebuttal could reportedly include a 110-game schedule in 2020.
MLB's proposal Tuesday included significant cuts to player salaries for the 2020 season - especially for the league's highest earners. This was met with heavy criticism.
New York Mets right-hander Marcus Stroman tweeted that "this season is not looking promising." Cleveland Indians starter Mike Clevinger said the players "will stay united," while Washington Nationals ace Max Scherzer responded by saying there's "no reason to engage with MLB in any further compensation reductions."
Both sides initially agreed to prorated salaries after the league was shut down in March. Owners are now arguing that the agreement needs to be amended due to fans being unable to attend games, while the players want the original agreement honored.
