With many MLB organizations curtailing or (as is the case with the Cubs) completely eliminating Fall Instructs, there are plans afoot to expand the Arizona Fall league (AFL) schedule in 2019 from the present six weeks (30 games) to eight weeks (40 games). If implemented, the 2019 AFL season would begin two weeeks earlier than it does now (the last week of September instead of the second week in October),
Because there is presently about a four-week gap between the end of the minor league season and the start of the AFL season, players assigned to the AFL have to spend a week to ten days at their parent MLB organization's minor league facility in Florida or Arizona getting back into playing shape before reporting to their AFL team.
