Sheikh Ahmed's daughter of Cape Cross had produced a string of good efforts this season including when second in the Group 2 Middleton Stakes and conceding 12lb when runner-up to Irish Oaks winner Covert Love in the Hoppings Stakes at Newcastle.
She travelled extremeley well under William Buick, who settled his mount on the heels of the leaders.
She quickened into the lead at the furlong pole before sticking on gamely to beat Speedy Boarding by half a length.
Roger said: "Talmada deserved to win a Stakes race and I am delighted she has done so. She is a talented filly with some very good form."
Shortly afterwards, Fool To Cry gained a first win in the 7f 100yds Auction maiden at Beverley.
The daughter of Fast Company came from the rear to get up close home under Jack Mitchell.
Roger added: "Fool To Cry found the seven furlongs at Wolverhampton too sharp last time and the stiff track has suited her today.
"There should be more to come from her up in trip."
