Hibernian head coach David Gray said his side were "reliant" on goalkeeper Jordan Smith to keep a clean sheet in their goalless Scottish Premiership draw with St Mirren.
Smith made a few fine stops as the hosts made it 12 games unbeaten and consolidated their hopes of a top-six finish, despite Alasana Manneh receiving a red card just 13 minutes into his debut.
The Gambia midfielder, a graduate of the Barcelona youth academy, came on in the 70th minute, was booked a minute later for a trip, then saw yellow again for a reckless aerial challenge on Killian Phillips.
"The clean sheet is a big positive because we pride ourselves on that," Gray said. "That's the biggest thing, because if you're keeping clean sheets then you can't lose games of football, so that's a good habit to get into.
"We were reliant on the goalkeeper, makes a big save in the second half. If you look at Rocky [Bushiri] getting man of the match, his defensive display was excellent.
"I actually thought we defended the box reasonably well and we needed to be defensively good because we were by no means good enough to really go and win the game.
"I thought it was a really poor game with no real quality within it. We found a way to not lose the game and, especially going down to 10 men as well, when the character would be getting questioned and tested, it would be easy to fold."
The visitors held on with 10 men for a point and remain in fifth place, while St Mirren jump to sixth, above Kilmarnock on goal difference.
