From the good old days without domed stadiums. IMHO, eliminate that day off and add it to somewhere else in the schedule when it's more needed for rest. Hell, I would add a doubleheader in the first series of the season and the first one after the allstar break since players are well rested at this time, this would allow a cpl more rest days for the players. I would also allow teams to add a cpl more pitchers for the next five games after a double header so not to burn out a staff.
