Major League Baseball's July 31st trade deadline has passed, but plenty of major league players will still be traded before the season is over. July 31 is commonly referred to in Major League Baseball as "the trade deadline," but the more accurate term is "non-waiver trade deadline." Teams may still make trades during the months of August and September, but the rules are very different.
Starting August 1 of each season, clubs can put players on "special waivers," also known as "major league waivers," "trade waivers," or "revocable waivers." Any player who could possibly be traded can be put on waivers and if they are claimed, the club can call them back without losing the player.
