Isn't the MLB trade deadline 7/31?

[TheProject]

And if so, how did the Diamondbacks and Dodgers swap players?

 

[bulldog3434]

players can be placed on waivers, and if they pass through waivers and nobody claims then, then they can be traded

The non-waiver trade deadline was 7-31. After that, a player must clear waivers before the trade can be completed.

How retarded.

What's the point of the deadline then?
