Chaz Mostert was the eventual winner of a bizarre third race at the Beaurepaires Melbourne 400 late yesterday, after his Tickford teammate Cam Waters collided with the previously undefeated Scott McLaughlin in a warm-up lap, forcing both the Monster Energy and Shell V-Power Ford Mustangs to miss the race.

Mostert will start from pole position for this afternoon's final race of the weekend, while McLaughlin will be back on the grid, starting from second, in front of Holden's best driver of the weekend so far, seven-time Supercars Champion Jamie Whincup.

In the second race of the weekend, a 13-lap sprint around the Albert Park Grand Prix circuit, McLaughlin got a solid start from pole to lead into the first corner, with Coulthard slotting into fifth, with Cameron Waters in second. McLaughlin set the fastest lap of the race on lap three, and had a two-second lead by lap five

Coulthard struggled with balance, tuning the car with the roll bars as he looked to pass Whincup who sat in fourth. By lap 10 the gap was over four-seconds, now to Mostert with Waters having been relegated to third.

Coulthard was solid in fifth, sandwiched between Whincup and Davison. As they started the last lap McLaughlin was three-seconds ahead of Mostert, eventually winning the 1000th ever Australian Touring Car/Supercars race by 2.5s to maintain his perfect start to 2019. Coulthard finished fifth.

McLaughlin again dedicated the victory to the people of Christchurch, his home town.

"It was awesome to win the 1000th ever Australian Touring Car race this afternoon. I love a good stat, so that's a very cool thing," McLaughlin said.

"It's a real shame about what happened this afternoon, but we race humans and humans make mistakes. I'm just really sorry for my team, who have a damaged car to repair tonight. Eyes forward, we get another opportunity tomorrow and we'll try to grab another win."

The second race of the day would be over before it began for McLaughlin in extremely bizarre circumstances. While on the out lap for the evening's 25-lap, 130km race, Tickford's Cameron Waters came into contact with McLaughlin, forcing them both into pit lane prior to the race start.

The damage was too great to repair, so McLaughlin's car did not start the race. With the front row of the grid empty, Coulthard's fifth place start effectively became a third placed start.

After a slow start, Coulthard slotted into fifth place on the road, and settled in there. By lap five was just under one second behind Reynolds.

A late Safety Car period was called when a wheel came off Shane van Gisbergen's Triple Eight Holden, however, the result was unchanged with Coulthard securing another fifth place finish. He is now sixth in the points.

McLaughlin continues to lead the Championship by 24 points over Whincup. The team remains at the top of the Teams' Points, with a 64 point lead over Triple Eight.
