Michael Cahill has history to support him when he says Someday can overcome an outside alley to win Saturday's Glasshouse Handicap.

Someday drew the widest barrier in the 16-horse field but Cahill remains upbeat about his chances of winning the Listed sprint.

"I rode Scenic Peak when he drew 20 out of 20 in the Glasshouse a few years back and he was good enough to overcome it and win," Cahill said.

"When the rail is in the true position and you get to the crown of the track it's not the end of the world to draw out wide."

Cahill rode Someday at Eagle Farm last Saturday when the gelding finished an unlucky third to Fire Up Fifi.

"When Diademe crossed me her jockey Blake Shinn took hold and I kept getting shuffled back through the field," he said.

"I certainly didn't set out to be back there but I couldn't go anywhere because I had horses improving to my outside."

Damian Browne, who rides topweight Belltone, agrees with Cahill that wide barriers aren't the obstacle they might seem in the Glasshouse.

"If you're going to be drawn badly then Caloundra's probably the place to do it," he said.

"You've got plenty of time to slot in before the first turn and I'd rather be drawn 12 to 14 then one or two and have to be worried about the whether the fence is going to be off."

Belltone has drawn two positions to the inside of Someday in stall 14 and will carry 59kg, a rise of 2.5kg on the weight he carried to victory in last year's Glasshouse.

The seven-year-old ran 16th to Linton in the Stradbroke Handicap on June 8 but Browne believes he has a class edge on his Glasshouse rivals.

"I don't think any other horse in the race is Stradbroke quality apart from him which is probably why he's got the 59kg," he said.

Browne is aiming for his second Glasshouse victory after riding Woorim when the gelding scored his second consecutive win in the race two years ago.
