Southend United 0-0 Wrexham
Wrexham remained second in the National League after being held by battling hosts Southend United.
In a tight first half, it needed a fine save from Collin Andeng-Ndi to deny Wrexham's Ollie Palmer.
Jake Hyde thought he had put Southend ahead against his former club after the break, only to be called back for a tight offside decision.
Nathan Ralph could have won it for the Shrimpers but could only head a dangerous cross over the Wrexham bar.
