Mackay said at his after match press conference "I'm frustrated after that, just like my players.
"With the amount of chances we created we deserved something, if not all three points.
"That's as good as we have played in the first half. We peppered their area and the keeper made a great save to deny Jon Harley.
"We've got to win as many games as we can between now and the end of the season.
"There are a lot of points up for grabs and if we play like that the ball will drop for us and we will score goals."
