Major League Baseball has proposed going back to a 15-day disabled list and increasing the time optioned players must spend in the Minor Leagues, according to a source.

The moves are aimed at increasing offense and reducing the use of relief pitchers.

The minimum DL stay was reduced to 10 days in 2016 as part of baseball's new labor contract. As a result, the use of the DL increased from 563 placements in 2016 to 737 last season.
