Christian Reith knew Agent Bauer was city class when he romped to victory at Hawkesbury last month.

But the improving stayer's dominant display on the Kensington track at Randwick two-and-a-half weeks later had the jockey reassessing his opinion.

Agent Bauer handled his midweek city debut with aplomb in a performance that has the jockey confident Wednesday's Listed Australia Day Cup (2400m) at Warwick Farm is well within reach.

The Gwenda Markwell-trained gelding has firmed to $2.90 outright favourite with TAB Sportsbet and he headlines a strong book of Australia Day rides for Reith.

"He's a nice stayer in the making, it's a big step up for him tomorrow but I'm pretty confident he can make that step," Reith said.

Reith first rode the son of Jeune to a 3-1/2-length win over 2000m at Hawkesbury on December 19 before the four-year-old stepped up to 2400m and was even more impressive on the Kensington track, winning by 6-1/2 lengths on January 5.

"The first time I rode him was at Hawkesbury, he gave me a lovely feel and even from that day I knew he was a town horse," Reith said.

"When he then came out and won on the Kenso, and won so impressively, it actually surprised me.

"He just keeps progressing, Gwenda has got him going great guns and I'm excited to ride him again tomorrow."

Reith returned to Sydney racing from Brisbane in March last year and has been getting good support from trainer John O'Shea for whom he has three Warwick Farm rides.

The jockey partnered the O'Shea-trained Viva Las to a narrow win at Rosehill on Saturday.

"He is putting my horses in the right spot to give them a winning chance and a trainer can't ask for much more than that," O'Shea said of Reith.

Reith says working with the Randwick trainer keeps him focused in the saddle.

"He's giving me these opportunities and I'm stepping up to the mark which is what he expects of me," the jockey said.

"He expects you to be professional and to give horses every possible chance and at the moment things are going well. I'm really enjoying riding for him, he keeps you focused and that's a good thing for me."

Among O'Shea's Warwick Farm team is three-year-old Pacquiao, a 7-1/2-length Gosford Maiden winner over 1200m on January 13.

Reith will partner him in the TAB Number 1 Club Handicap (1400m) while Nash Rawiller has the ride on stablemate Freyberg.

Not A Snip A Doubt and Private Label are other O'Shea-trained runners Reith will partner.

"I've got a real nice book of rides and that's what it's all about, you've got to have the right cattle," the jockey said.

"I've got to put them in the right spot and steer them the right way and then the rest is up to them. On their work they should all be competitive."
