Saints let Caersws off lightly
TNS had no trouble seeing-off bottom club Caersws, but missed the chance to top the Welsh Premier table on goal difference.
They opened-up a four goal lead before half-time, but were unable to add to their tally after the break to leave Llanelli still top of the pile.
It took a smart save by Paul Harrison to stop bottom of the table Bluebirds taking a shock lead through Geraint Lewis, but the Saints wasted little time in opening their account when Jamie Wood slotted home the first on six minutes from a Craig Williams inside pass.
Ryan Marriott and Alex Darlington both went close before Marriott added the second on the half hour with a well taken effort from Wood's pass.
Williams blazed over from four yards out after a Chris Seargeant shot had been blocked, and keeper Dave Jones did well to save from Darlington in a one-on-one.
But a short free-kick released Darlington who turned and fired his shot past Jones for the third. A superb pass from Darlington found Williams whose shot was parried by the keeper, but Seargeant fired the rebound into the far corner on the stroke of half-time.
TNS were never as effective in the second-half although it took a great save from Jones to keep out Wood's 20-yarder.
But the visitors almost reaped some reward for neat build-up play only for Mark Griffiths to fire straight at Harrison, who then denied the same player after Matthew Prosser had robbed Steve Evans.
Williams should have added to the Saints' tally late on, while the same player and sub Steve Abbott just failed to profit from a cross.
