Forget Leicester City, the Chicago Cubs, Ireland and the rest of them - this may be the biggest upset of the sporting year.
Here's the scene.
The University of Maryland has the best college soccer team in the United States. Ranked No. 1, they went through the regular season with 18 wins and 2 draws. Undefeated, and en-route to claiming the NCAA Division I championship.
They had a free ticket in the first round of the NCAA knockout stages before coming up against Providence in round two.
Providence went for 12 wins and 6 losses in their regular season - in a conference that is hardly considered "heavyweight" - and defeated Delaware in the first round.
