All the sweeter for the Yorkshiremen was the fact that their coach Jon Callard had been discarded by the West Country side last season, Leeds hooker Mark Regan also being a former regular at the Rec.
Leeds had to wait until the death to claim the points though, Bath centre Olly Barkley missing a tough touchline conversion in the 85th minute which would have shared the points.
That attempt came after Simon Danielli’s injury-time try, but it was not to be for the home side, who outscored their opponents three tries to one.
Barkley had himself earlier scored a try to add to Matt Perry’s five-pointer, but it was the boot of Leeds’ South African Braam van Straaten that did the damage.
He hit five penalties and a conversion, with second-row Tom Palmer touching down their only try, as they continued their superb start to the campaign after a miserable last season.
