The daughter of Dubawi has won at Thirsk and Lingfield already this month but this was her best performance to date off top-weight.
Dominic Fox, who has been on board for all her wins, was again in the plate and all went smoothly.
She was handy,sat on the shoulder of the leader, Sputnik Sweetheart who raced up against the favoured stands' side rail.
With over a furlong to run all of her rivals were in trouble and Baheeja stretched clear to win by two lengths.
Roger said: "She has really improved given some proper summer ground. She has a great attitiude and seems to enjoy racing."
