Lancaster had gone four games unbeaten in all competitions and looked full of confidence early on, but were stunned in the 25th minute when Thomas converted a penalty after an initial foul on the attacker.

The visitors had come close early on when Aaron Bennett forced Shane Bland into a save, and Nic Evangelinos struck narrowly over the crossbar.

But, despite these early chances, it was Whitby who took the lead from the penalty spot after Thomas was adjudged to have been fouled inside the area. He stepped up to send Andre Mendes the wrong way.

Thomas then sent an effort from inside his own half agonisingly wide after he spotted Mendes off his line, but Town would have a second shortly after with half-time looming.

Then Thomas came close again, this time with a much less spectacular low shot which was held comfortably by Mendes.

Two minutes before the break, Layton Watts found Simpson at the near post with a corner delivery as the striker registered his first goal back in blue since returning to the club from Sacramento in Australia.

Brayden Shaw fired into the hands of Shane Bland via a deflection in a rare opportunity for the away side in the second half.

And Whitby continued to push for more, netting a third in the 61st minute. A sublime bending ball from Campbell Darcy picked out Watts, making his home debut, who rounded the on-rushing Mendes before slotting home into an empty net.

In stoppage time, Town were grateful for Darcy who did all he could to protect the clean sheet, cleaning off the line after Whitby had initially failed to clear following a right-wing cross.

Only the injury to Jassem Sukar which saw Alfie Jackson replace him late in the second half threatened to dampen spirits at the Towbar Express Stadium but Whitby were back to winning ways as they climbed into the top half of the Pitching In Northern Premier League table.
