Wtf does this even mean
It means that the loss, while an upset, is not an "upset of monumental proportions." Didn't Stony Brook have 7 or 8 guys drafted? Thats an awful lot of talent on that roster. It's not unheard of for smaller schools to compete in baseball. All you need is for your team to get hot at the right time and servicable pitching. Stony Brook had both.
Yes, it sucked, but hardly was embarrassing.
