 During a 2015 Lamar Hunt U.S. Open Cup match against the Portland Timbers on June 16, however, Obafemi Martins left the game with a groin injury and Clint Dempsey was suspended after tearing a referee's pocketbook, though he would be called away for the 2015 CONCACAF Gold Cup.The injury and suspension of the team's main attacking duo led to a death spiral during the summer, with Seattle winning only one match in nine games.By late August, Martins had recovered and led the team to an 8-match unbeaten streak to secure a playoff spot, finishing fourth in the Western Conference.
