Dwayne Dunn is in the enviable position as the regular jockey for two of the most exciting sprinters in training and will be more than happy if Team Hawkes keep Chautauqua and Deep Field apart.

Dunn rode the the world's third-highest ranked sprinter Chautauqua and the unbeaten Deep Field to comfortable wins in jump-outs on Friday at Flemington and gave the stablemates the thumbs up.

"I had a couple of jets out this morning and they are both going really well," Dunn said.

"They will appreciate this morning's gallop around here. They should tighten up with fitness and it's exciting times going into the autumn."

This month's Lightning Stakes could be a first-up target for valuable entire Deep Field to chase his first Group One success.

The son of the late Northern Meteor is unbeaten in five starts.

The Newmarket Handicap looks a logical target in Melbourne for multiple Group winner Chautauqua who was runner-up to Terravista in the Darley Classic.

Co-trainer Wayne Hawkes suggested on Melbourne radio station RSN that Chautauqua could resume in the Group Two Rubiton Stakes on Saturday week.

Dunn said he would be surprised if the pair's programs clashed with senior trainer John Hawkes non-committal about their programs.

"Probably John's biggest asset is how to place them properly and he'll work out which one is fit enough to go to the races first and go from there. I would like them not to clash and I think the stable would probably prefer that as well," Dunn said.

Deep Field cruised to lead his heat and Dunn was pleased with how he dashed to the line under no pressure in 48.42sec to win by about a length.

Chautauqua sat just off the leader before moving to the front mid-trial and extended nicely in the straight, clocking a quicker overall time of 47.18sec to win his heat by about 2-1/2 lengths.

"Deep Field idled really well to the corner and picked up nicely," Dunn said.

"Chautauqua stepped really well. I couldn't really get him in behind them as is his normal racing pattern so I didn't really want to fight him.

"I just let him come through his gears and he extended really nicely to the line."
