The Scarlets region local derby went the way of the Drovers who followed up the win over Cross Keys with another very strong performance at Church Bank.
They conceded a second minute converted try to wing Jordan Williams but then strode confidently on to gain a thoroughly deserved bonus point win.
Playing into a stiff breeze, Llandovery found it difficult early on half but eventually got on the scoreboard after 20 minutes with a penalty from fly half Jack Maynard.
There was plenty of attacking intent on both sides and Llanelli scrum half Justin James made one clear break only to run out of support in the home 22.
Llanelli were giving a lot of penalties away but defended hard in the face of mounting attacks.
Llandovery centre Matthew Jacobs was almost over from fully 50 metres, denied by a desperate tackle from replacement Matthew Owen.
The deadlock was broken when lanky wing Aaron Warren exploited an unguarded blind side to race over unopposed to make it 8-8 at the break.
Straight from the restart, a sweeping move from the home backs ended with centre Rhodri Jones crossing, Maynard converting.
With the wind in their sails, a bubbling Llandovery pressed and full back Will Thomas accelerated away for another converted try.
Llanelli defended stoutly enough and even threatened the home line on occasions but eventually fell to the bonus point try, made by scrum half Lee Rees, scored by No 8 Richard Brooks and converted by Maynard.
Llandovery 32 - 8 Llanelli RFC
