They're only up 1-0, but Michael Rapaport tells TMZ ... San Antonio Spurs fans can break out the brooms, 'cause they're going to SWEEP the Miami Heat in the NBA finals.

The former "Prison Break" star -- who was leaving Bootsy Bellows nightclub in Hollywood -- admits it's a "lofty prediction" ... but M.R. ain't no dummy when it comes to basketball.

In fact, he was the MVP of the 2010 NBA All-Star Weekend Celebrity Game ... so ... that's gotta mean something. Right?
