Major League Baseball and the players union are set to meet on Tuesday to discuss a plan approved by owners on Monday to get the 2020 season started again.

Part of that agreement involves a new plan to share revenue.

The owners originally agreed in March to prorate players' salaries if there was a 2020 season. Instead of prorating, teams now want the players to agree to a 50-50 revenue-sharing agreement since it's clear most, if not all, of the season will be played without fans in attendance.

"A system that restricts player pay based on revenues is a salary cap, period. This is not the first salary cap proposal our union has received. It probably won't be the last," union head Tony Clark said.

"That the league is trying to take advantage of a global health crisis to get what they've failed to achieve in the past — and to anonymously negotiate through the media for the last several days — suggests they know exactly how this will be received.

"None of this is beneficial to the process of finding a way for us to safely get back on the field and resume the 2020 season — which continues to be our sole focus."
