Palace gave Premiership Reserve League leaders Charlton Athletic a spanking on Monday night to move within a point of top spot.
Goals from Tom Soares, Neil Shipperley and Ricci Dolan, as well as a Mark Fish own goal, ensured Palace recorded a reserve team double over the Addicks.
The Eagles could now go top should they win their game in hand on Charlton.
Palace XI: Speroni, Boyce, (Wilson 45) Borrowdale, Hudson, Popovic, Togwell, Andrews (Smith 86), Soares (Dolan 45), R Hall, Shipperley, Torghelle
