It's all over at the Oval. Second-half goals by Hrvoje Plum, Robbie McDaid and Marcus Kane secure three points for Glentoran having fallen behind to Cathair Friel's opener in first-half stoppage time.
Marcus Kane's header surely seals the points for the Glens!
Robbie McDaid turns the game on its head with a close-range header!
Hrvoje Plum brings the hosts level with a fine strike after some fine work by Robbie McDaid.
Friel's goal is the last action of the half as the irate Glentoran players storm down the tunnel.
Cathair Friel opens the scoring for Ballymena United from the penalty spot, but it's a hugely contentious goal.
Jude Winchester wins the penalty after being fouled by Conor Pepper.
Friel steps up, but it's a weak penalty which is easily saved by Antolovic. The rebound comes back to the Sky Blues striker, who makes a hash of his rebound as the Glens 'keeper gets across to palm the ball away.
However, referee Tim Marshall awards a goal having adjudged that the ball crossed the line before Antolovic made the save.
A hugely dramatic end to what's been a dull first half.
