There is little room for family loyalty in Group races and that is just as well for trainer Anthony Cummings.

Cummings is the son of master trainer Bart and the pair enjoy a friendly racetrack rivalry.

They will find themselves in opposition corners at Rosehill on Saturday when Bart's exciting colt So You Think lines up against the little-known Bach from Anthony's stable in the Gloaming Stakes (1800m).

It might look a mismatch on paper.

So You Think stamped himself a potential star of the spring when he unleashed a whirlwind finishing burst to run second by a nose to More Than Great first-up in the Ming Dynasty Quality, propelling him to the third line of Caulfield Guineas betting.

Bach is still a maiden after four starts.

But that hasn't stopped Anthony Cummings from declaring So You Think vulnerable on Saturday and making a case for Bach to beat him.

"Plainly he's going to be one of the toughest to beat, it was an excellent run the other day," Cummings said.

"But second-up over 1800 metres that's always a bit of a challenge.

"He might be the best horse there but he might be lacking a bit of fitness.

"We've got a couple of extra runs under our belt and I think if I'm going to take him on I'd rather do it there (Gloaming) than take him on a couple of weeks later."

Bach was paid up for the Spring Stakes at Newcastle on Wednesday but Cummings scratched him in favour of the Rosehill feature.

The colt has had three runs this campaign, the latest when he made late ground for sixth to fellow Gloaming hopeful Gathering over 1550m on the Randwick Kensington track on September 2.

Cummings has been happy with each of his efforts and believes he will continue to improve as he is stepped up in trip.

He also thinks the colt has turned the corner after he was able to resolve a few of his bad manners.

"He gives every impression of being a nice horse over ground," Cummings said.

"We've been trying to work out a few little chinks that he's had, and his mannerisms, and that's why there has been a bit of time between runs but he has responded to that well.

"He used to get on his Melbourne leg all the time and not switch onto his Sydney leg and just get his head up and get a bit awkward.

"We've spent a bit of time on him and now we've got it right and are hoping to get a bit of a pay day out of it."

The Cummings family is also set to saddle up rival runners in the Group Two Hill Stakes (1900m) in which Anthony has Zavite and Nothin' Leica Cat while Bart will start AJC Australian Derby winner Roman Emperor.
