Darren Weir saddled up four winners at Caulfield on Saturday but things didn't exactly go to plan in the feature race and he was far from pleased with riders Damian Lane and Craig Williams.

Lane, who piloted Humidor, and Williams on Amelie's Star, both came under criticism on RSN's Racing Pulse show on Monday morning, with Weir saying neither rode to instructions.

"I wasn't happy with the rides, wasn't happy with the first part of the race with either horses, or either jockeys," Weir told Michael Felgate. 

"They (Humidor and Amelie's Star) weren't trained to be ridden that way and things just didn't go ideally from there."

Amelie's Star, usually a backmarker, was ridden aggressively from barrier 13, charging across to lead in the early stages of the 2400m race. 

Williams then handed up to Sir Isaac Newton who commenced to overrace badly, with Amelie's Star rolling on a fast pace in third. 

When asked if Williams was instructed to go forward on the mare, Weir gave a blunt response of "not really."

"Craig dug his out from the barrier and made her go forward which was a surprise to me."

Amelie's Star, a $9.50 chance, straightened for home in second but was a spent force at the 150m and faded out to finish 11th, beaten 5.3L.

Post-race, Williams was complimentary of his mount's performance.

"I was really proud of her performance. She had a really sticky barrier draw and we wanted to offset that and have her in a really forward position," Williams said.

"She was able to do that. She was amazing but she had to use petrol to get there. It was a gallant effort in the circumstances."

Weir was similarly disappointed with Lane's ride on Humidor ($6.50), saying he was shocked to see the former New Zealand galloper so close in the run.

"Damian said the crowd got Humidor going a bit halfway down the straight but I don't know about that. He had his chance to slot in I thought and elected not to and was then more forward than I anticipated," Weir said. 

Humidor travelled in the first four before joining the leaders at the 300m.

As he did in the Turnbull Stakes (2000m), Humidor wanted to lay in under pressure and proved a handful for Lane over the final furlong.

The five-year-old gelding battled on gamely to finish fifth, 2.6L off shock winner Boom Time.

"He ran well. I settled a lot closer than I anticipated and he got fired up going past the winning post the first time. When I went for him, he hung like a rusty gate and cost himself the race," Lane said shortly after the race.

Weir told Felgate that both runners pulled up well but he hasn't a clear idea of where we'll see them next, saying that the team will monitor their progress over the next few days.

The Weir-trained Kiwia (R5) was the only winner all day to come from the second-half of the field, with the track heavily favouring on-pace runners.
