Add these future stars to your fantasy baseball squads now, and you will reap the considerable rewards down the line.
Keeper league owners must place one eye on the present and one on the future. This is not, however, clearance to embark on a rebuilding project that sets your team back for the next three years. There's no need to toss any chance of immediate success down the drain.
But in most leagues, it wouldn't hurt to roster a prospect or two still waiting for the nod to the show.
If any of these top minor leaguers are sitting on the wavier wire, scoop them up before it's too late. It will pay off when they're headlining your squad in a couple of years.
Keep in mind that this list assumes the keeper league does not contain a prospect system. All these prospects should be long gone in formats that conduct minor league drafts before the season starts.
