Mazda fell from first to third when Peugeot emerged as minor premiers after defeating the former ladder leaders 18-14.

The best match of the contest saw Mirco Gatti withstand a tremendous fightback from Scott McKinnon before winning in five.

Also in the fixture, Paul DeMamiel avenged his first-round loss by accounting for Ian Carter in four games.

Toyota consolidated their finals position with a narrow 17-16 win against Subaru. 

Adrian Baird looked ominous when he won the first two games 10-9, 9-0 against Nic Calcutt.  However, Calcutt rallied to win the match in five, but Baird's three points helped his team to consolidate their chance at a spot in the major semi-final.

The luckless Audi team remained wooden spooners, even after notching an impressive 19-16 victory over Nissan.  

Anthony Ippoliti was on fire when he defeated Vince Staltare in three, and Phil Priest also performed well to defeat David Parrot in four. 

Kay Cunningham kept Nissan’s finals hopes alive with a win against Jason Cooney before Adam Taylor defeated Matt Kirkman in four and helped his side finish equal fourth on the ladder with Subaru.

A countback of winning rubbers throughout the competition was needed to separate Subaru and Nissan, but when rubbers were also equal, a count of all competition points saw Nissan snatch a finals berth by only 12 points.

Tomorrow night, Peugeot will play Toyota in the major semi-final, with the winner qualifying for the grand final.

The sudden-death final will see former leaders Mazda take on Nissan.
