Harrysson 0-0 Pietreczko (2-1)
Image source, Getty ImagesAndreas Harrysson has already caused one major upset this year, eliminating 12th seed Ross Smith in round one. He is very much the underdog again here.
One thing Harrysson does have though, in the words of Hot Fuzz, is a great big bushy beard. It is quite exceptional facial hair.
And he has game too - a hold of throw here after a 95 finish. Some excellent darts from the bearded man so far.
Harrysson 0-0 Pietreczko (1-1)
There are some very loud German fans in the audience chanting for Pietreczko. But Andreas Harrysson is not cowed as he hits another 180.
Pietreczko responds with 140 to set up a 121 finish - but is just wide of the bull!
Harryson is on 82 again, but this time is well down on tops. Pietreczko cleans up.
Harrysson 0-0 Pietreczko (1-0)
Is Andreas Harrysson nervous about his debut at this stage? Well, he's thrown a 180 with the first visit of the game. That may be your answer.
Harrysson gets to a finish of 82, and bangs in tops to convert. Excellent start from the Swede.
Harrysson v Pietreczko
Ricardo Pietreczko is nicknamed 'Pikachu' because of his soundalike surname, and walks on to the classic Pokemon cartoon theme song.
My little 90s nerd heart is swelling. Love it.
Harrysson v Pietreczko
Right, let's play darts.
First up we have a meeting of two unseeded players both enjoying an unexpected post-Christmas adventure at Ally Pally.
That certainly is the case for Sweden's Andreas Harrysson - the 50-year-old came through qualifying and is making his World Championship debut.
Standing in the way of Harrysson's dream run continuing is the German world number 33 Ricardo Pietreczko. The winner here faces fifth seed Jonny Clayton in round four.

Will be interesting to see how Littler handles the slow style of Suljovic tonight - one things for sure, he won't speed Mensur up!

Luke Littler has come through [the first two rounds] pretty unscathed, although he could have lost a set in his previous match.
It doesn't look like the pressure's got to him of being a defending champion and I don't think it will affect him tonight.
Mensur is a slow player but each player he's played has been quite methodical so that's nothing new for Luke and I think he'll be fine.

Fifth seed Jonny Clayton needed a deciding set to eventually overcome world number 44 Niels Zonneveld and reach the last 16 of the PDC World Championship.
Welshman Clayton, 51, was back in action after a 12-day break, having received a bye through to round three because his second-round opponent Dom Taylor was suspended for failing a drugs test.
The first six sets of a high-quality match all went with the throw, Clayton moving a set in front of Zonneveld on three separate occasions, but the Dutch left-hander kept responding in an impressive display.
However, the former Premier League champion found the key break of throw in the second leg of the deciding set before sealing victory.
Luke Woodhouse, the 25th seed, defeated fellow Englishman Andrew Gilding 4-1 to reach the fourth round for the second successive year.
Woodhouse will next face Poland's Krzysztof Ratajski, who beat Dutchman Wesley Plaisier in a deciding set.
Welcome back to our live text coverage of the PDC World Darts Championship, where we have three more matches from round three to come this evening.
Players run the gamut from qualifiers and lesser-known hopefuls, to some of the biggest names in the sport - none bigger than top seed and reigning champion Luke Littler, who is involved in the final match on stage tonight.
Don't go anywhere.
We are going to pause this live text now, but will return in a couple of hours for the evening session.
Catch up with what happened in Saturday's afternoon session in our daily report.
Tonight we will see some of the biggest names in darts, including "people's champion" Stephen Bunting and defending world champion Luke Littler.
See you then.
Result: Clayton 4-3 Zonneveld
Jonny Clayton, speaking to Sky Sports after beating Niels Zonneveld in a deciding set:
"I don't watch the games but I follow all the results. It's a chance [to go far in the competition], I'm not going to lie. I look and see there's another gone, it gives me more hope that I can do it.
"I'm looking forward to every time I walk on this stage and I feel good."
Result: Clayton 4-3 Zonneveld
Given Jonny Clayton had not played for 12 days before this match, he will be very satisfied with that performance.
A 98.44 match average, 11 180s and 46.67% checkout rate is not to be sniffed at.
Clayton will face Swedish qualifier Andreas Harrysson or unseeded German Ricardo Pietreczko in the round of 16.
Result: Clayton 4-3 Zonneveld
Niels Zonneveld averaged 99.36 in that match against the fifth seed, threw seven maximums and 27 140-plus visits, and hit a highest checkout of 126.
He can exit these world championships with his head high.

Clayton 4-3 Zonneveld (3-0)
Jonny Clayton gets two match darts - and lands the second in the D16.
A huge celebration from Clayton, that shows how hard he had to work in this match. A massive test from Niels Zonneveld, passed by the fifth seed.
A reminder that Clayton is a real contender for the title this year.
Clayton 3-3 Zonneveld (2-0)
What on earth has Jonny Clayton done here? He's chucked in an opening visit of 42 to completely hand momentum back to his foe.
He shakes that off with a couple of big scores, and with Zonneveld also struggling, Clayton needs 86 to win...
