Blackpool survived relegation despite Callum Harriott's hat-trick securing Charlton a third win in four games.

Harriott, who also scored twice in the 3-1 victory over Watford on Tuesday, slotted home to put the Addicks ahead.

The 20-year-old added his second of the afternoon after being teed up by Jon Obika, before adding a late third.

Blackpool, who started the day in 19th place, finished the season two points above the relegation zone as Doncaster lost and Birmingham drew.

Losing end for Blackpool Blackpool had only lost once in eight years on the last day of the season before today - against Manchester United on 22 May 2011

It was a close shave for the Seasiders, who were in the Premier League three years ago.

In a turbulent season, manager Paul Ince was sacked in January, with caretaker-boss Barry Ferguson having won just three of his 20 league games in charge.

But they started the final game knowing a point would be enough to guarantee safety.

And they started brightly, with Stephen Dobbie forcing keeper Ben Hamer to tip his 13th-minute shot behind.

Defender Craig Cathcart then headed Tony McMahon's free-kick over as the hosts created the better chances before the interval.

But Harriott's clinical finishing proved the difference.

The former England Under-19 international opened the scoring in the 61st minute with a neat finish before completing his hat-trick with two goals in the final eight minutes.

His second, a left-footed strike after brilliant work from Obika, gave keeper Matt Gilks no chance.

And the Norbury-born winger completed his hat-trick in the last minute, latching onto Joe Pigott's pass and firing low to the left of Gilks.

Blackpool caretaker manager Barry Ferguson:

"It's a strange day because we should be really happy keeping the club in the Championship.

"But I just wanted the boys to go out on a high.

"This isn't the way I wanted to finish it."

Charlton manager Jose Riga:

"I asked my players to end the season with a good feeling and they were able to do it."

On Callum Harriott's hat-trick:

"He has speed, he has pace and it's more a question of trying to manage his emotions.

"Everybody knows that he has talent."
