The winner of Sunday's $150,000 Bow Mistress at Elwick will remain in the state for the $150,000 Vamos Stakes at Mowbray on Launceston Cup Day.

Numerous mares have won both races but, surprisingly, very few have done it in the same year. Flewella (2002), Nuclear Free (2005) and Lady Lynette (2011) have been the only exceptions.

Life On The Wire, I Love It and Rebel Bride won both races but in different seasons.

Hayes' stable foreman in Melbourne, Gary Fennessy, said the Vamos was actually the main target for Zargos.

"We started aiming her at these races a month ago because we thought they were a good chance to get a bit of black type," Fennessey said.

"The 1400m of the Vamos is really her go but we thought if we freshened her up she could also win over 1200m - and she did, with the help of a very good ride."

Zargos got home narrowly over local filly Deroche after her rider Blaike McDougall got a split in the home straight.

Craig Newitt was looking for a similar opening on Deroche but it came too late and she looked a certainty beaten.

Last year's Vamos winner Twitchy Frank was only a long head away in third.

Trainer Glenn Stevenson is set to inherit another Victorian for his Wesley Vale stable.

Nero Veloce, winner of Sunday's Class 1 Plate over 2100m, is likely to stay in the state according to his Cranbourne trainer Matthew Brown.

"There's a benchmark 66 coming up for him in Launceston so we'll leave him with 'Stevo" for a while," Brown said.

"We brought him over for the Derby last year but he travelled poorly."

Nero Veloce still managed to finish a respectable fifth behind Cossetot but then went to Mowbray and got beaten in a much weaker race as odds-on favourite.

"He thinks about it so you've got to catch him on his day," Brown said.

Nero Veloce was ridden by Ben Allen who later copped a two-meeting suspension for mid-range careless riding on Platinum Angel in the Bow Mistress.

His fellow Victorian rider Zac Spain was banned for one meeting for excessive whip use on Appmat in the Hobart Cup - 12 hits before the 100m when the limit is five.

Victorians will break a five-year drought in Tasmania's premier two-year-old race at Mowbray on Wednesday night - if the early market is right.

The Tony McEvoy-trained Jyoti is $2.60 favourite with tab.com.au for the $150,000 Gold Sovereign.

The David Hayes-trained Avenue Of Pleasure is second favourite at $5 with Blushed the shortest of the locals at $8.50.

The last Victorian to win the race was Gold Busker in 2015.
