Dungannon Swifts manager Kris Lindsay has warned he will not accept any drop-off in effort from his players over the rest of the season.
The Swifts have little to play for in the league, with the threat of relegation gone and it seemed to show as a dismal display was punished by Carrick Rangers, who ended a six-game losing run.
It was a stark contrast to Dungannon's performance in a 1-0 win at Ballymena earlier in the week.
A frustrated Lindsay said: "We pretty much got what we deserved today, which is disappointing. We talk about playing the teams around us, and we haven't got much against them.
"So far this season Warrenpoint have beaten us here, Portadown have beaten us here and now Carrick have beaten us here. That's not good enough and it's something we have to rectify, and quickly."
The game had produced few clear-cut chances until Carrick took a 39th minute lead. Cathair Friel was fouled on the edge of the box and Mark Surgenor stepped up to curl home a sublime free-kick.
Dungannon stepped up the pressure without creating much and Carrick wrapped it up when Jordan Gibson converted Lee Chapman's pass 11 minutes from time. Neither team can be relegated after the Champinship season was scrapped, but for Lindsay that is no excuse to ease up.
He added: "There is a lot riding on these games. I don't like losing games, I don't like performances like that. It is not a free ride to the end of the season by any stretch of the imagination. Players are playing for contracts, players are playing for their futures, they are playing for my future as well.
"It is not a case that there is no relegation so we will coast it - that is not going to happen."
