Two horses unbeaten in Australia have provided the motivation for champion jockey Glen Boss to make the first of two scheduled Brisbane winter carnival appearances on Saturday.
Boss is making the trip to the Doomben meeting with an expectation Rhythm To Spare will stamp himself as a serious Queensland Derby chance in the Grand Prix Stakes.
Melbourne's leading jockey also feels import Midsummer Sun has what it takes to make it three wins from as many Australian starts when he runs in the Premier's Cup (2200m) on his way to the Brisbane Cup.
Rhythm To Spare, trained by Mike Moroney, had a New Zealand Derby preparation aborted because of shin soreness but has since won a Bendigo maiden and then a midweek 1600m race at Sandown when Boss had his first ride on the gelding.
"He gave me a really quality feel when I rode him at Sandown," Boss said.
Boss said he felt Rhythm To Spare was "going to launch" and win convincingly at Sandown but didn't go right through his gears on a surface the jockey described as "pretty rock-hard".
"Even though the margin wasn't big, for me he was still really impressive," Boss said.
Rhythm To Spare is on the third line of betting for the Grand Prix (2200m).
"I'd expect him to nearly win tomorrow," Boss said.
The Sam Kavanagh-trained Midsummer Sun is favourite in the Premier's Cup on the back of a last-start 1-1/4 length win with Boss aboard over 2000m at Caulfield.
"He gave me a really good feel as well. The margin wasn't huge but I felt like he's the type of horse who'll lift when the company lifts," Boss said.
"So I figure he's going to be a really good Brisbane Cup ride."
He said it was going to be interesting to see the progression both horses have made.
Boss is set to be back in Brisbane for Stradbroke day.
