The 2013 University of Oregon Invitational concluded with Sam Schwartz & Keegan Williams-Thomas from Cleveland High School defeating Lake Oswego for the Robert Clark championship.

In 2014 Schwartz & Williams-Thomas were back in the UO final round and once again had to fend off challengers from Lake Oswego - this time Max Groznik & Ammas Tanveer. Tanveer walked into the round having just been given the Top Speaker Award.

Cleveland affirmed the resolution "The USFG should ratify CCBW" (a treaty banning chemical and biological weapons) and, on a 2-1 decision, defended its tournament title.

Cleveland High School also won the novice division; Jesuit High School (coming all the way from Sacramento, CA) placed second.
