This was ultimately in vain, as Plange netted his hat-trick 62 minutes in. Grante again played a defence-splitting through ball pass down the right for Plange to get on the end of, he drove into the box before picking out the top corner on his left foot.
The south Londoners almost netted a fifth with 15 minutes to go, after a well-worked short corner between Jack Wells-Morrison and Mathurin almost found Craig Farquhar at the back post, but there was just too much on the delivery.
The Villains pulled another goal back with 10 minutes to go, as Omari Kellyman picked out the top corner with a free-kick 20-yards from goal on his left foot.
There was almost a possibility of a grandstand finish, when Lamare Bogarde found himself through on goal just moments after the free-kick, but Whitworth stood tall to pull off a fine stop.
Palace saw out the remainder of the game, with Mathurin almost being in for a fifth late on, to move up to 11th place in the Premier League 2. They are three clear of Manchester United and one behind the likes of Reading and Middlesbrough.
