Bristol De Mai made every yard of the running to land his first Grade One over fences in the Betfred TV Scilly Isles Novices' Chase at Sandown.
Nigel Twiston-Davies' grey came into the race on the back of an impressive Haydock success and jumped economically in front for Daryl Jacob.
Tea For Two and As De Mee kept close attendance on Bristol De Mai, but the 10-11 favourite got away from the Pond fence much the best and kept a remorseless gallop all the way up the straight.
As De Mee won out in the battle for second place, but was six lengths down at the line.
Jacob said: "I think you can put him where you want to (in a race) now. The more racing he is getting, the better he is getting.
"He's only a young horse and there's lots to look forward to."
