Seattle Sounders defender Shane O'Neill (27) heads in a goal against FC Dallas during the second half of an MLS playoff soccer match, Tuesday, Dec. 1, 2020, in Seattle. As in his one previous MLS goal before Tuesday night. The Sounders will face either Minnesota United or Sporting Kansas City in the West final next Monday. But O’Neill found himself unmarked in front of the Dallas goal in the 49th minute and flicked Nicolas Lodeiro’s corner kick past Dallas goalkeeper Jimmy Maurer. It was the first Seattle goal by someone other than Lodeiro, Raul Ruidiaz and Jordan Morris in the past five matches.
