The Metro Series is an annual college basketball rivalry game between the Detroit Mercy Titans and the Oakland Golden Grizzlies.

This created a natural rivalry for the Titans, and with annual matchups between the two Detroit area schools now guaranteed for the foreseeable future, the Metro Series, as it began to be known, started to take off.

Known as the Michigan Sports Hall of Fame Cup, it is awarded to the winner of the season basketball series between the two schools.

Should the schools split the series, the cup is awarded to the team with the better Rating Percentage Index (RPI) at the time of the game.

[1] Oakland has historically dominated the series since its inception, with Detroit Mercy having only won three games against them since the Golden Grizzlies first joined the Horizon League and winning ten straight matchups from 2017 to 2021.
