Can a baseball team trade their draft picks?

Draft picks cannot be traded. In addition, a player once drafted cannot be traded until 1 year to the day after signing. This explains a lot of times when a player is traded for a player to be named later, (Jeremy Bonderman was a player to be named later in the Jeff Weaver trade in 2003 because Bonderman signed on August 2, 2002 but Weaver was traded on July 6, 2003 so Oakland had to wait until August 2, 2003 to trade him so he was called a player to be named later)
