Apprentice Peter Wells has played a major part in a big day out for his boss Graeme Rogerson with two wins at Canterbury including the feature event, the Lord Mayor's Cup, on frontrunner Penrickson.

Rogerson was in Brisbane on Saturday where Awesome Planet staked her claim for the upcoming Queensland Oaks with victory in the Doomben Roses.

In Sydney, foreman Roger Elliott oversaw proceedings where the day kicked off with victory by More Than Cash ridden by Rod Quinn then Wells booted Rendzina home for his first win since returning from an enforced break due to a broken foot.

He was reunited with Penrickson in the Lord Mayor's Cup (1900m) after winning three races on the gelding in December.

Wells allowed Penrickson to stride to the front and he stretched his lead to around six lengths in the back straight.

Although he seemed to be coming back to the field, Penrickson ($5.50) pulled out plenty and held off Music Review ($12) by a head with Prince Arthur ($15) a half-neck away third.

"It's been a great day for me," Wells said.

"And this horse just loves Canterbury and being allowed to bowl along."

Wells is Sydney's reigning premier apprentice and comes out of his time in July.

He outrode his claim two days before his accident and spent a month on the sidelines.

Penrickson came into the race off a game third to Macknuckle in the Wagga Cup (2000m) on May 1.

"His run at Wagga was good and set him up nicely for today," Elliott said.

"I'm not sure where he goes next. Graeme may have something in mind for him.

"But it was good to see him win today. He loves this track and it was a great ride by Pete.

"Over the last 50 metres I was a bit anxious but Pete rated him perfectly and he just keeps on going."

Wells said the key to Penrickson was not to fight him.

"He is a phenomenal runner, he just keeps going," he said.

"You can hold him up but he doesn't like it so the key to him is just to let him go along in front."

Elliott said there was a chance both Rendzina and Penrickson could head north to Brisbane for some of the minor features over the rest of the winter carnival.
