Lewes suffered their third defeat in four games, falling to a disappointing 3-0 loss at Wingate & Finchley.
Tony Russell made two changes to the side that lost 3-1 at home to Carshalton Athletic in their previous game, with Archie Tamplin and Ryan Gondoh replacing Marcus Sablier and Tommy Wood in the starting line-up.
These changes saw Ola Ogunwamide play through the middle as a centre forward, as he had done in the latter stages of the Carshalton game.
Ogunwamide could have given Lewes an early lead, as he saw his effort from a tight angle saved by Ben Goode in the Wingate goal.
The Rooks continued to enjoy the better of the early chances, with Tamplin the next to call Goode into action after exchanging passes with Ogunwamide on the edge of the area.
The hosts were struggling to gain a foothold in the game, seeing Elliot Long shoot straight at Nathan Harvey with their first meaningful attempt at goal.
Lewes continued to look the more likely scorers, Chris Whelpdale forcing a smart save from Goode, who then reacted well to keep out Kalvin Lumbombo-Kalala’s effort on the rebound.
It was therefore against the run of play when Wingate took the lead on 34 minutes, Long beating Harvey with a low strike from the edge of the area.
Long doubled his and Wingate’s tally barely a minute later, controlling an excellent cross from Ahmet Biler before firing a superb finish across Harvey and into the bottom corner.
He could even have completed his hat-trick before the break, dragging his shot wide after a long ball forward had caused havoc in the Lewes defence.
Wingate were well on top at the start of the second half and made it 3-0 on 50 minutes, as a powerful long-range strike from Ruben Carvalho beat Harvey.
Lewes were unable to find a route back into the game as the second half progressed, with the hosts looking more like adding to their lead if anything, as Alexander Solomon vollied a Carvalho corner just over the bar at the near post.
The closest the Rooks came to a late consolation saw Goode bravely save at the feet of Ogunwamide after a Whelpdale knockdown.
The rest of the game passed without any meaningful chances, with Lewes now hoping to bounce back when they welcome Billericay Town to the Pan on Tuesday, kick-off at 7.45pm.
