Jim Richards ate into John Bowe's Touring Car Masters series lead with victory in Round 5 at Sandown.
The Ford Falcon Sprint driver improved third and seventh place finishes from the opening two races on Saturday with a win in the final.
The result came after a mid-race mistake from early leader Kim Jane at Turn 9.
Andrew Miedecke finished second in Race 3 ahead of Jane, Jason Gomersall and Race 2 winner Greg Crick, while Bowe managed just ninth.
Richards subsequently trims Bowe's points lead by 10 to 48 ahead of next month's round at Bathurst.
“I've always liked this place, I came here for the first time in 1975 and have raced here every year since,” Richards said.
“I thought at the start I would be fourth or fifth in that one and the big cars would get me on the straight, but when Kim made his mistake I was able to take advantage and get through.
“I don't know what happened to John but he got a terrible start and that helped.
“I was quicker than the guys in front but it was hard to pass and once I was in front I had to scrap for it – I was looking in the mirror.
“It's been a great weekend and I'm looking forward to going to Bathurst and then getting the Javelin back on track.”
The result marked Richards' seventh TCM win at Sandown and his 19th podium from 24 starts.
