United via the 2011 MLS Re-Entry Draft, and the signings of out of contract players Michael Gspurning and Adam Johansson.

A week later, in the 2012 MLS Supplemental Draft the Sounders took University of California-Santa Barbara defender Tim Pontius and former Leicester City F.C.

On the same day as the Supplemental Draft, the Sounders traded the rights to defender Leone Cruz, whom the Sounders acquired in the second round of the 2011 MLS SuperDraft but did not sign to a contract, to Real Salt Lake for UCLA defender Andy Rose, whom Real Salt Lake had drafted in the first round of the Supplemental Draft.

The Sounders played 50 matches during the 2012 season across all competitions and including major friendlies—the most in the team's history.
