The Major League Baseball Players Association will respond to the league's latest CBA proposal on Sunday, sources familiar with the situation tell ESPN. The league made a "last and best offer" during bargaining sessions in Florida on Tuesday, just hours before commissioner Rob Manfred canceled the first two series of the regular season. That offer included CBT (competitive balance tax) thresholds well below what the union has been asking for as well as a large gap between the sides in a pre-arbitration bonus pool. The meeting on Sunday comes three days after the sides met in New York for 90 minutes on Thursday as the union has been prepping a response in the interim. One major issue, which connects many of the economic terms, is the number of teams in an expanded postseason.
