James Douglas admits he was "in shock" when his shot found the back of the net in Tuesday's 'Big Two' derby. The teenage midfielder's deflected effort earned Glentoran a 1-0 win over Linfield at Windsor Park.
It is the third time this season the Glens have beaten their arch rivals, following successive Premiership victories.
Dluglas - who was sent off when the sides met last month at the Oval - was the hero on Tuesday, firing home in the 88th minute to book his side's place in the quarter-finals of the BetMcLean Cup.

The 18-year-old said: "It is a massive result for us. It was back to the walls during that second half, but thankfully we found a way and got the winner.
"I knew I was in a bit of space on the edge of the box, and I just tried to anticipate the ball coming in and where the clearance header would go. And luckily enough it fell to me.
"I just tried to make good contact and it took a deflection. It was a bit of luck but I'll take it.
"I was shocked when it hit the back of the net. I couldn't believe it. But then I just felt joy.
"It is my first senior goal and I suppose it wasn't a bad time to get it. It was a a great way to score my first goal and I won't forget it.
"I thought I was unlucky to get sent off last time, but we still got the win which was the most important thing. It was good to come back tonight and, maybe not right the wrongs, but it was good to get a goal and win again."
Douglas admits playing in a 'Big Two' derby is a "special" occasion, and one that adds some extra nerves and excitement.
He added: "It is unbelievable being in the middle of it. The atmosphere is electric, and every tackle and throw-in is celebrated like a goal. It is easy to find energy. It is unbelievable.
"You do get a bit nervous beforehand, but it isn't too bad. And once the game starts you just get into it."
Reflecting on his career path at the Oval, Douglas said: "I have been at the club since I was 13 and come through the ranks. I know the club inside out.
"I had a great journey through the academy. I have worked hard to get to where I am, and I just have to keep working hard.
"I am playing in such a great team, and alongside so much experience in midfield. And we have some great young players, too. It says a lot about the academy at Glentoran."
