Andy Jenkins produced his best performance in 13 years of competing at the highest level to knock Adrian Lewis in Purfleet.

The 35-year-old from Hampshire won 4-3 to reach the quarter-finals for the first time, having never previously gone beyond the second round of either the Lakeside or Circus Tavern versions of the world title.

He had to do it the hard way, for Lewis - protege of 13-time world champion Phil Taylor - made his usual blistering start and led 2-0 before Jenkins roared back in a match played at a frantic pace.

The next three sets went to `Rocky', who took advantage of his opponent's dip in form with Lewis perhaps distracted by a continual desire to fist-tap after any big scores or out-shots.

But despite the excellent spirit in which the contest was played, there was no quarter given and Lewis levelled it up at 3-3 to set up yet another decider in a tournament full of epic encounters.

This one did not go the full distance though, for Jenkins put in a fantastic leg against the throw when 2-1 up and showed tremendous composure, needing only one dart at double 12 to close it out.

"I'm over the moon with the way I came back," said 12th seed Jenkins, playing only three weeks after the death of his father.

"I dug deep and really played well. With everything that has gone on recently, I'm as chuffed as nuts.

"That has shown me I can produce my best on television. It's fantastic against a quality player like Adrian. He will be a future world champion - but not this time."
