plural matchups
A pairing of two things, people or teams, especially for a competition quotations examples
It's not an arcade game—there is no crack of the bat or roar of the crowd or even much in the way of a screen display—but for the true fan, there is the excitement of mathematically structured matchups of real current and past teams with a more-than-passing resemblance to real-life outcomes.
