Never Ending galloped shortly after the start of the Alex And Harley Hello Pace (2130m) at Gloucester Park on Friday night, but still powered to the line to finish third behind Louie Dior.

As well as his unbeaten run ending by galloping out of contention, Never Ending was also placed out of the draw for this week's $100,000 event.

Despite the disappointment of defeat, Justin Prentice said he still had confidence Never Ending could add the three-year-old Westbred Classic to his win in the two-year-old event last year.

"He seems really good," Prentice told The Trots WA.

"He pulled up super on Friday and had a blow, which he always does.

"Within no time it looked like he hadn't even had a run.

"You could tell in the run Junior (Gary Hall Jnr) was doing the right thing by the horse and the times suggested he hadn't hurt himself."

Never Ending headlines the nominations for the Westbred Classic and is joined in the event by the likes of Skylord, Rocket City and Louie Dior.

Prentice said while the wide draw would be tricky for Never Ending, he was capable of having to do work in his races.

"I know he's led in quite a lot of races as a two-year-old," he said.

"When he has led and over raced, it's like he's working anyway.

"He's made mid-race moves in the past because he's capable of doing that."

Prentice also nominated stablemate Miki's Beach for the Westbred and indicated he could measure up against some of the state's better three-year-olds.

The gelding won his first two starts, before he finished a game third behind Louie Dior at Pinjarra at his most recent start.

Prentice said he hoped Miki's Beach lack of race experience wouldn't count against him getting a start in the race.

"I really think he's good enough to win it with the right run," he said.

"He was probably the run of the race behind Louie Dior, then he came out and beat Never Ending.

"He's taken a lot of time to get to where he is and there's not much between him and a horse like Rolling Fire on ability."
