Leicester put last season's heavy defeats to Bath to bed with a 21-11 victory in poor conditions at Welford Road on Sunday.
Mike Ford's men opened the scoring through Anthony Watson's superb try but the hosts came back into the encounter and led 11-5 at the break.
Tommy Bell kicked two penalties and Telusa Veainu intercepted a stray pass to help the Tigers build a six-point buffer.
George Ford levelled matters in the second period via a pair of three-pointers, but Dan Cole's try and a further Bell effort off the tee secured the win for the home side.
Leicester have struggled for fluency over the past couple of years but, with the addition of former New Zealand international Aaron Mauger to the coaching staff, there have been signs of improvement.
However, they found themselves 5-0 down early on against last season's Premiership finalists.
Horacio Agulla, Niko Matawalu and Matt Banahan all combined to send England international Watson scampering across the whitewash for an early advantage.
Leicester's fly-half responded for the hosts from the tee before Nick Auterac had his pass intercepted by Veainu and the Tongan representative raced away down the left-hand side.
It was a hammer blow for the visitors who were on the front foot and Bell's second penalty made it an even more frustrating first period.
The West Country outfit improved after the interval and successive Ford three-pointers levelled proceedings.
Ed Slater, the Tigers' lock, then received a yellow card as a dominant Bath maul powered towards their line, but they couldn't take advantage.
Instead, Richard Cockerill's men held out and Bell restored Leicester's lead from the tee.
With eight minutes remaining new signing on his Bath debut David Denton was sin-binned for the away team, and Cole went over soon after to seal the win.
