The Pirates acquired catcher Chris Snyder and Minor League shortstop Pedro Ciriaco from the D-backs in exchange for three of the team's veterans -- Ryan Church, Bobby Crosby and D.J. Carrasco The deal was officially announced three hours before Saturday's 4 p.m. ET non-waiver Trade Deadline. The Pirates also received $3 million from the D-backs to help offset part of Snyder's salary. Over the next month, deals involving players on the 40-man roster cannot be made unless the players already have cleared waivers. A player exposed to waivers can be claimed by any team and -- if there are multiple claims -- the player would be offered to the team with the worst record. At that point, a team has 48 hours to either try to work out a trade with the claiming club or remove the player from waivers. A player can only be pulled back from waivers once, but if he clears waivers either the first or a second time through, a team can attempt to trade him to any club.
