Glentoran boss Declan Devine said his side's dramatic 1-1 draw with Ballymena United was "extremely hard to take".
Christie Pattison had given the Glens the lead early in the second half at the Showgrounds, but they were hit with a late sucker punch.
Substitute Joe More equalised for the Sky Blues deep into stoppage time and Devine was frustrated his side couldn't hold on to claim all three points.
"The players all disappointed, they should have seen the game out better, we have to accept we took a kick in the teeth right at the death," he told BBC Sport NI.
"To concede in that manner when we were under pressure, it was about game management and seeing the game out, but I can have no complaints with the players and their application."
The result for the second-placed Glens extended their unbeaten run in all competitions to 16 matches.
They will now turn their attentions to their third away game in the space of a week as they face Cliftonville at Solitude in a game that is live on the BBC iPlayer and BBC Sport website.
"It's a Belfast derby against a huge football club," Devine added.
"We're going into their back yard, and they'll be fresh from not playing this week, so it's a game we should look forward to."
