Adelaide United continue to lose ground on A-League leaders Melbourne City following a 0-0 draw with Wellington Phoenix.
The hosts saw Ryan Strain sent off 16 minutes from time to dampen hopes of a late rally, with Carl Veart's men winless in four.
Adelaide are now six points behind City and have played a game more, with a trip to Melbourne to face their rivals next on the agenda.
Having been held to a goalless draw last time out against Western United, Adelaide started brightly and Stefan Mauk should have capitalised on Josh Cavallo's fine delivery, but instead miscontrolled when well placed.
Tomi Juric saw a strong header saved smartly by Oliver Sail as the home side pressed, but after a blank first half ambition had to take a back seat when Strain got his marching orders for a second yellow card after he kicked the ball away.
