Major League Baseball has considered playing seven-inning doubleheaders during the shortened 2020 season.
The Cleveland Indians and Chicago White Sox played the first twin bill of the year on Tuesday.
Tony Clark called deputy commissioner Dan Halem this week and said players might want to consider shortened twin bills this year.
The players' association is surveying members and might propose either two seven-inning games for a doubleheader, or nine innings for the opener and seven for the nightcap.
MLB is checking opinions among owners and general managers, and league staff hope for a decision by Saturday to make a change or leave the rules the way the are, according to a source.
