DAVE Chisnall and Michael Smith went through to the second round of the partypoker.com World Grand Prix after winning sudden-death legs in Dublin - but Stephen Bunting has been knocked out.

Chisnall progressed after winning the night's most dramatic clash as he escaped from four missed match darts from Peter Wright to snatch victory from the jaws of defeat.

Wright edged a tight opening set 3-2 after Chisnall missed two darts at double 12 in the fifth leg to claim the lead, only for the 2013 Dublin runner-up to take the second set 3-1 to level.

Wright moved 2-0 up in the decider, but missed the bull for the match in leg three and the saw Chisnall finish a 13-darter to send the game into a sudden-death leg.

Wright landed a 180, but missed three more match darts to allow the Premier League semi-finalist in to take out 60 on tops to claim a narrow triumph.

"It was very hard and I had to keep battling," said Chisnall. "I gave him that first set by missing the double 12 and I had to dig in, but I won and I'm happy with that.

"Peter was quite good with his doubles and I didn't think he'd miss at the end, but it was always going to go to the wire."

Chisnall now plays Jelle Klaasen in round two, after the Dutchman knocked out Northern Ireland's Brendan Dolan by coming from a set down to win 2-1.

Klaasaen said: "I'm very happy and I feel confident. In the first set I missed too many doubles but I was opening well and I felt confident that I could win the game and I'm happy with the way I played.

"It's difficult to play against Brendan but Dave has the same rhythm as me and I hope if I can keep opening like this that I'll have a good chance to win. We're both playing well in the floor tournaments so I hope we can show it on stage."

Number eight seed Michael Smith overcame two missed match darts from Gerwyn Price before claiming a dramatic sudden-death leg win over the Welshman.

Price, on his World Grand Prix debut, kicked off the game with a 160 opening score and won the first set 3-1, but Smith hit back from a leg down in the second to level the game with two 14-darters and also found himself behind in the decider.

Price led 2-0 in set three, with Smith hitting back with a 100 finish before capitalising on two misses from the Welsh ace - at double top and ten - to send the game into a one-leg shoot-out which he claimed on double 14 with a whitewash as his opponent missed 15 starting doubles.

"I didn't get going but Gerwyn let me in and I took my chances," said Smith. "I've played a lot better here and lost, so to get the win I'm happy because I've never won here before.

"During the game I felt like I was playing like the world number 100, but I kept telling myself that I'm the world number eight and to start playing like that, and I battled through where two years ago I'd have lost this game.

"I'm into the last 16 for the first time and it's the business end of the tournament. I've not proven myself on TV yet so that's my focus now."

Smith will now meet another Welshman, youngster Jamie Lewis, in the second round on Tuesday after the Cardigan-based thrower saw off Ireland's William O'Connor 2-1 in another game which went all the way.

But there was defeat for the third St Helens man in tournament - Bunting.

Welsh left-hander Mark Webster held off Bunting's fightback with a superb deciding set as he moved into the second round with a 2-1 up.

Webster – who is battling to maintain his top 32 status - came from a led down to win the opening set 3-1 before Bunting found top gear to win the second set in a deciding leg, despite finding himself 2-1 down at one stage.

The left-hander, though, took out 70 and 104, for a 12-darter, to move 2-0 up in the deciding set, before punishing Bunting's missed doubles by firing in tops for the win.

"I really enjoyed that," said Webster. "It was a big game but I've never lost to Stephen before and I was confident and I thought I did okay.

"Stephen missed too many doubles but when he got back to one set all and it was big, mentally, to get back on top and knock the stuffing out of him in the final set.

"I'm in the last 16 and I'm really pleased."
