The Chris Waller-Tye Angland show has continued at Randwick with the pair combining for three winners including I'm Imposing who claimed a sentimental victory in the Shoot Out Handicap.

Shoot Out was trained by Waller to win three Group One races after arriving at the stable as the winner of the Randwick Guineas and Australian Derby.

Angland, who returned to Sydney in May near the end of his fourth riding season in Hong Kong, racked up four winners at Rosehill two weeks ago, three for Sydney's premier trainer.

Waller believes the Hong Kong experience has been the making of Angland who drove I'm Imposing ($16) to a one length win over Single ($8).

"Hong Kong irons out mistakes in jockeys and Tye has come back a very, very good rider," Waller said.

"We like to use the best jockeys we can and we are having a lot of success with Tye."

I'm Imposing almost left the Waller stable with his owners, who include racing commentator Richard Callander, considering a recent offer which failed to materialise.

The eight-year-old came back to 1600m on Saturday from the 2000 of his previous race a month ago.

"He has had a freshen-up," Waller said.

"I have always thought he is a good horse over a mile and I wanted to win a race named after Shoot Out.

"Even though we are a big stable, we still get attached to the horses, especially a horse like Shoot Out and I'm thrilled we have won."

Shoot Out's owner Linda Huddy was on hand for the win named after one of her best horses who now lives on her Sunshine Coast property.

Waller and Angland also combined with Specific Choice in the TAB Rewards (2000m) and Forever Crazy in the Spring Carnival (1600m).

Specific Choice had not won since November 2012 and Waller admitted he had worked hard on his mental attitude.

"He was over racing, so we have had to concentrate on those shorter races," Waller said.

"It was just a matter of getting him in the right head space. He has always shown ability and now he is in the right zone I think he should keep going."

It was Angland's first ride on the four-year-old and he said he had studied his races.

"I have seen his last couple of runs and he is not 100 per cent honest but, in saying that, he did a good job today," he said.

"I was in a lovely position in behind the speed and working my way up. I had cover right around the corner and he let down nicely."

The treble took Waller to 153-1/2 wins for the season, 14 short of his record total in 2012/13 with six meetings remaining.
