Conor Coady's second half goal from a cross-cum-shot gave the Terriers all three points. Mackay was keen to defend his goalkeeper Scott Carson after noticable criticsm from supporters of his recent performances.
“I’m disappointed; the boys put terrific effort in today and to be beaten by what looks like a cross in the top corner is particularly unfortunate,” Mackay said.
“We were beginning to look really dangerous in the second half and then young Callum McManaman ends up pulling his calf and has to come off when he really looks as if he’s going to go at them.
“I thought we were pressing them in the second half and we kept going but the goal is one of these freak things.
“We had the penalty claim as well and it really does look like a penalty because the cross comes into the box and Joel Lynch’s hands aren’t in a natural position and the ball strikes both of them so we’re disappointed with the way in which the ball isn’t rolling for us at the minute.
“That’s just the way it is at the moment and we’ve just got to make sure we get our heads back up and don’t get too down-hearted because the performance was reasonable and we’ve got to make sure we take that into next week.”
The result leaves the Latics in the bottom three on twenty-one points, five points adrift of Rotherham in 21st place.
The Latics travel to face Ipswich Town next week who currently sit in third place and convincingly beat the Latics at the DW Stadium earlier this season.
