PETER WRIGHT overcame World Youth Champion Michael Smith with a thrilling 4-3 triumph in the last 16 of the Ladbrokes World Darts Championship.

Smith, who created shockwaves around the darting world with his sensational win over reigning champion Phil Taylor in the second round, came from a set down to lead 2-1 and also movd 3-2 up as he took out a fabulous 136 checkout to win the fifth set.

Wright, though, recovered to win six of the next seven legs to pull through to reach his first World Championship quarter-final, and will now play Wes Newton for a place in the last four.

"It's probably the best performance I've ever produced in a televised game," said the colourful Wright, who ended with a 105.07 average - eclipsing Adrian Lewis' superb 103-plus effort in round two against Vincent van der Voort.

"I'm shattered right now, it was very nerve wracking. Michael was playing amazing and I was just trying to keep with him. I maintained my level and was sharper on my finishing in the last two sets.

"Many people think I'm just a bloke with a flashy haircut and a loud pair of trousers, but I can really play good darts and I've shown that this year."

Both players traded 14-darters at the start of the match, before Wright edged ahead by taking the third leg, after Smith wasted four darts at doubles.

The St Helens ace then won the fourth leg in 13 darts to level, only for Wright to reply in kind with a 13-dart finish of his own to take the first set.

Smith hit finishes of 74 and 118 to take a 2-0 lead in the second set, before Wright hit back to win the next two legs, landing a fantastic 161 checkout to break throw in the third.

The deciding leg saw Smith leave 40 after 12 darts, and he held his nerve with an accurate third dart at double top to level the game, with his opponent waiting on 45 for a two-set lead.

The first two legs of set three were shared, which included a 136 checkout from Wright in the second, before Smith edged ahead with an 84 finish.

Wright levelled with a 15-darter, but Smith held his throw in the decider by converting a 70 finish to edge 2-1 up.

The fourth set fell into a similar pattern of the previous three, as it also went to a deciding leg - and Wright opened with two 140s against the throw before taking out 116 to square the contest.

Wright then won the first leg of the fifth set, before Smith won the next two, taking out a 60 finish in the third after Wright missed two chances at double 12.

The fourth leg proved to be a brilliant one from both players as Smith kicked off with a 180 before Wright hit back-to-back maximums to leave 41, only to see the St Helens youngster take out a fantastic 136 checkout to win the set in brilliant style and lead the game 3-2.

Wright replied to take the first two legs of set six before Smith converted an 88 finish to win the third and keep the set alive.

The number 16 seed, though, won the set with an 82 finish in the next leg, and kept that form up in the final set, as finishes of 95 and 84 saw Wright move a leg away from victory.

Smith hit a tenth 180 as he fought back in leg three, but scores of 140, 140 and 105 from Wright saw him pull clear, and an accurate attempt at double ten sealed a memorable win.
