The MLB trade window was closed Tuesday afternoon, but teams still have the opportunity to make waiver-wire deals through the end of August.
This is a complex process, but if deals are made by September 1, those players will be eligible to compete in the postseason.
Here's how it works:
If a player clears the waiver wire, his team is free to negotiate around the league. If he's claimed, the team can either discuss a deal with that team or renounce the player's rights.
While teams like the Los Angeles Dodgers, New York Yankees and Philadelphia Phillies were busy prior to the trade deadline, the Cleveland Indians, Colorado Rockies and Oakland A's did not complete major trades prior to the July 31 non-waiver deadline.
