I was a little vague with my paraphrasing, sorry. The proposal is to start at 600k next season and be at 700k by the end of this next CBA. It's not a whole lot better than status quo from what I can tell.
"Major League Baseball has offered to increase the minimum salary from $570,500 to $600,000, which would rise to $650,000 and $700,000 through the CBA."
