Leading jockey Kerrin McEvoy and trainer Peter Snowden combined to extend their recent domination of the Group Two Sandown Guineas on Saturday.

McEvoy rode the Snowden-trained Tatra ($5.50) to a long head win over the Bart Cummings-trained favourite Lunar Rise ($5) for the jockey and trainer's third win in the race since 2008.

Four years ago they won with Caymans and then they snared the race the following year with Kidnapped.

Snowden narrowly missed the quinella this year with Proverb steaming home for third, only a short half-head behind Lunar Rise.

Both McEvoy and Snowden admitted Tatra was not an elite performer but praised his determination.

"Lunar Rise was coming at me but my fellow just dug deep," McEvoy said.

"He's no world-beater but he's a good old grinder and gives his best.

"He's always shown nice promise and he's gotten stronger and better throughout his preparation last time and this time as well.

"He toughed it out well and it was nice to win this race again."

Snowden and McEvoy had a day out at Sandown after they earlier collected the Listed Twilight Glow Stakes (1400m) with Meidung.

Meidung and Tatra are both owned by Sheikh Mohammed al Maktoum whose brother, Sheikh Hamdan al Maktoum, owns the winner of the opening race, Bulbula.

Snowden said that Tatra and Proverb had been selected at the start of the Melbourne spring season and aimed at races within their reach.

"These are two horses that we identified fairly early in the carnival and thought, well, they're not A-graders, they're not (Caulfield) Guineas horses but they're the next level down," Snowden said.
