The former Newcastle man galvanised his side with his introduction in the second half. He was a constant aerial threat and helped his side get back into the game when he took his chance well when presented with the ball just mere yards out in front of the goal.
But the main talking point of the game came late on when Carroll powered in a header from a Luis Suarez cross that the Liverpool players thought had crossed the line before Petr Cech clawed it out.
But the goal was not given, and Cech was adamant that was the right decision.
He told ITV: "I don't think it was over the line. If the ball was behind the line I couldn't have kept it out. I'm 100% sure it was not in, and I felt that from the first moment."
Unsurprisingly, Carroll argued the opposite view, and said his own fine performance was of little consolation.
The much-maligned striker said: "I thought it was over the line. I thought it hit the other side of the bar. We were unlucky. We had a few chances but we couldn't put them away. It wasn't to be."
Liverpool manager Kenny Dalglish insisted the officials should get all the credit if they called the toughest decision of a dramatic FA Cup final correctly.
With Liverpool's players believing they were back in the game referee Phil Dowd consulted his assistant Andrew Garratt, who ruled it was no goal. Television replays were not conclusive as to whether the ball had crossed the line, although computer graphics suggested later it might have done.
Dalglish, however, said: "I've not seen it on television but somebody said sometimes you get it and sometimes you don't. This time we didn't get it. If the officials have got it right I hope they get the credit they deserve for it.
"It is credit to the lads that they went close to getting an equaliser after big Andy scored, but we left ourselves too much to do and I don't think the first hour was a true reflection of the quality of the players.
"They were excellent for the last half hour but the game lasts for 90 minutes and with a team the quality of Chelsea you can't give them two goals start and expect to give yourself an opportunity to get something from the game."
