Darren Weir is hoping Mahuta's winning streak can continue through to the Australian Guineas after a narrow win at Caulfield.

Mahuta collected a sixth-straight win when successful in the Autumn Stakes on Saturday and will chase his first at Group One level in the Australian Guineas at Flemington on March 5.

Ridden by Brad Rawiller, Mahuta ($3.20) scored a short half-head win from Sailing By ($14) with Snoopy ($6.50) a half-length away third.

Weir said Mahuta hadn't spelled since he made his debut at Seymour in September with his beachside stables at Warrnambool and blinkers keeping Mahuta in winning form.

Mahuta progressed from a Kyneton maiden win in October to the Sandown Guineas in November, remaining in work for a trip to the Gold Coast and taking out the Magic Millions 3YO Guineas last month.

"He's a very tough horse," Weir said.

"He's the sort of horse owners dream of."

Weir said Mahuta wasn't impressive in his win on Saturday but the horse did it the hard way.

"It was his first run in five weeks but was fit enough for the run," he said.

"He walked a bit in the last 100 yards but five weeks between runs, that will give him a good clean out."

Mahuta had his price trimmed from $6 to equal favouritism at $5 with stablemate Palentino for the Australian Guineas ahead of New Zealand galloper Xtravagant at $6.
