I'd actually prefer a 3 game series, with the first game at the 5th place team and a double header the next day at the 4th place team.
So a sample
NL
Monday - 4 at 5
Tuesday - 5 at 4, 5 at 4
Wednesday - 3 at 2
Thursday - 4/5 at 1, 3 at 2
Friday - 4/5 at 1
Saturday - 2 at 3
Sunday - 1 at 4/5, 2 at 3
Monday - 1 at 4/5
Tuesday - 3 at 2
Wednesday 4/5 at 1

Same schedule but start on Tuesday with first Monday off. That way there is never more then 3 games on any given day and at least 2 games every day (if they go 5 of course) except the first Monday and the second Thursday.
