Wilde keeps Saints on title track
TNS pocketed another three points to leave them needing just 11 from their last eight games to retain the title.
The game was settled by a single goal on the hour when, from a quickly-taken Scott Ruscoe free-kick, Nicky Ward mis-hit his shot and the ball fell sweetly for Michael Wilde to pop into an empty net for his 16th goal of the campaign.
Rhyl battled hard but were generally easily contained by a back four which featured an impressive display from Michael Jackson alongside Baker, Evans and Holmes.
A bad tackle by Stuart Graves after just two minutes put Jamie Wood out of the contest, with Martyn Naylor slotting into midfield in his place.
Chris King brought a fine save from Lillies' new keeper John Gann after 17 minutes when set-up by Holmes, while Wilde went close to opening the Saints' account when Timmy Edwards made a mistake.
Wilde was just wide from six yards from a Naylor corner, with Rhyl's Greg Stones forcing Gerard Doherty into action just before the break.
Once in the lead, TNS should have put the game beyond doubt but Nicky Ward was guilty of two glaring misses. Twice the frontman broke clear with only Gann to beat, but grazed the foot of a post with his first effort and sent his second sailing over the bar.
Andy Moran had two snap shots readily saved by Doherty as Rhyl went in search of an equaliser, with Wilde's overhead kick just wide at the other end.
Sub John Leah then brought a superb save from Gann with a 25-yarder before Chris Adamson's surging run from midfielder ended with a shot that was only parried by Doherty and it took a last-ditch tackle to deny Lee Hunt.
