The victory of Master Of Arts in the Warrnambool Cup has given Darren Weir his biggest haul at the three-day carnival.

Weir opened with a quartet on Tuesday, had a double on Wednesday while Master Of Arts provided him with the second leg of a double on Thursday.

The victory was also Weir's third-straight Warrnambool Cup success after victories by Akzar in 2014 and Tall Ships.

Ridden by Dean Yendall, Master Of Arts ($8) scored by a 1-1/4 lengths from Vilanova ($31) with Swacadelic ($5.50) 1-1/2 lengths away third.

"These are the races you set horses for," Weir said.

"The jumpers, the Wangoom and the Cup are the main races and then you just run anything else that is around at the time in the other races.

"We had plenty of runners but at this carnival it's very hard to win."

Weir had three runners in Thursday's Cup with Master Of Arts the least fancied of the trio.

Master Zephyr was sent out the $3 favourite before finishing fourth and Falago ($7.50) was seventh.

"It's great for this horse to win for Paul and Angela Fudge who are big supporters of ours," Weir said.

"Paul came up and had a look around and they ended up sending me a couple of horses.

"They have beautifully bred horses and deserve all the success they get."

Weir said Master Of Arts could return to Queensland this winter and be set for the Caloundra Cup at the Sunshine Coast.

Master Of Arts headed to Brisbane last year for the Queensland Derby but had his campaign cut short by a knee problem after running third in the Grand Prix Stakes.

A plan hatched by Weir's track walker Peter Ellis was followed to perfection by Yendall.

While Yendall was able to get out wide, Brad Rawiller was stuck on the inside and unable to get to the best going.

Rawiller cut the corner and got to the lead but Master Zephyr was unable to keep the run going.

"It was a terrific ride by Dean," Weir said.

"They had parts of the track where they had to get to and he got the job done.

"Unfortunately Brad didn't get to the part he wanted."
