Goals from Barry Corr and David Worrall saw Southend United make it four league wins in a row after they defeated 10-man Northampton Town.
Jack Payne wasted a great early chance for the Shrimpers when he fired wide of the right-hand post from close range.
Northampton goalkeeper Jordan Archer was then sent off after spilling a cross and bringing down Corr, who fired in the resulting penalty.
Worrall made it 2-0 when he swept home a left-wing cross from Myles Weston.
Northampton Town manager Chris Wilder tells BBC Radio Northampton:
“We think Stewart Murdoch has pulled his hamstring. They (the injuries) are hurting me more than anybody can say.
“Some players have not done themselves any justice today. You’ve got to sometimes ride with it until you can change it round.
“My patience is running low on certain aspects. I don’t like the inconsistency of our team”
