Rubbermatch 

Most commonly used in boxing and MMA (mixed martial-arts), a rubbermatch is the third (and tie-breaking) match between two teams or individuals who have previously beaten each other once.

After the outcomes of Couture vs Liddell 1 & 2, a rubbermatch was inevitable to decide the superior fighter.

The tie-breaking game between two baseball teams in a series. They call it a rubber match because the winning pitcher receives a tote bag full of condoms. All rubber matches are sponsored by Trojan. The policy was implemented in 1957 when pitcher Guy Hugesac died of "explosive syphilis" while pitching game 7 of the World Series.

Josh Beckett won the rubber match today! Thank God he won't be dying of explosive syphilis any time soon.
