JOHN HENDERSON came through an incredible five-set battle to send world number seven Dave Chisnall crashing out of the 2014 Ladbrokes World Darts Championship.

Henderson took the first two sets and was within touching distance of a straight sets win before Chisnall came roaring back to win the next five legs and force a deciding set.

The number seven seed held the initiative in the decider, but let four darts to win the match slip away and Henderson held his nerve to claim a famous victory.

"I feel speechless at this moment. I'm just so relieved to have won," said a delighted Henderson.

"Even at two sets up I knew that Dave would really come back at me which he did and I felt my chance may have gone.

"Somehow I managed to stick in during the deciding set and I've now got my first win on this great stage. I would have to class this as my biggest win."

Henderson won the opening two legs of the match only for Chisnall to reply and claim the next two, and the number seven seed looked on course to take the set in the deciding leg.

However, Henderson stunned his opponent with a brilliant 122 checkout to take the first set before doubling his advantage by taking the second without reply, including a party-piece 132 checkout of two bullseyes and double 16.

Chisnall was 2-1 down in the third set and a leg away from going out but found double 18 to his liking as he hit the bed in five successive legs to force a deciding set.

The fifth set proved to be a dramatic affair as Chisnall missed three chances to win the match in the fourth leg and was off-target with another match dart, at the bullseye, in the sixth.

Those errors proved to be expensive for the World Grand Prix finalist as Henderson won the decider 5-3 in the tie-breaker to progress to the second round.
