SEATTLE — Columbus forward Jeff Cunningham — and former Real Salt Lake player — became the leading goal-scorer in MLS history when he converted a penalty kick in the 59th minute in the Crew's 6-2 loss to the Sounders. That was his 134th goal, eclipsing the previous mark set by Jaime Moreno in a 15-year league career, 14 of which were spent with D.C. United.
