Ireland's Steve Lennon and William O'Connor are through to the second round at the PDC World Championships.
Lennon showed resolve in a pulsating contest at Alexandra Palace as he fought back to win 3-2 against Exeter debutant Owen Bates, who had held a two-set lead.
Carlow native Lennon won nine of the last 11 legs against the 21-year-old crowd favourite to claim the win needed to retain his PDC Tour card.
"I don't know how I won that," he said. "I was panicking deep down, it's a massive win."
Bates had qualified through the PDC Challenge Tour and hit five 180s and producing 101 and 108 second-set checkouts.
But Bates missed five doubles for a 2-1 lead in the fourth set as Lennon, who hit six maximums, grew stronger and booked a second-round meeting with Welshman Jonny Clayton.

Limerick's O'Connor, meanwhile, had a far more comfortable time with a 3-0 victory over Bhav Patel.
The Indian left-hander was close to a 157 finish but he failed to win a single leg and the impressive O'Connor - who hit 64% of his doubles and averaged 98.74 - will play Chris Dobey next.
Poland's Cork-based Radek Szaganski took to the stage on his Alexandra Palace debut wearing the colours of the Irish flag.
Szaganski overcame Finland's Marko Kantele 3-2 with a final set 142 checkout helping him through to a second-round clash with five-time world champion Raymond van Barneveld.
Did Ross Smith just get stung by a wasp live on-air?! 🐝🤣 pic.twitter.com/7VUybFK6x9

Number 16 seed Ross Smith was stung by a wasp on stage at the World Championship after avoiding second-round pain to Niels Zonneveld.
Smith eased to a 3-1 victory over Zonneveld before running into problems.
"There's the wasp," Smith said in his post-match Sky Sports interview as he noticed the insect.
The Englishman then recoiled in pain and said: "He's just stung me like a good one. Little bugger."
Smith, a prolific maximum hitter, was below his best but still produced seven 180s and the second 170 checkout of the tournament to see off plucky Dutchman Zonnevald.
"It wasn't a great game and I didn't play nowhere near what I can," said Smith. "But I can enjoy my turkey and pigs in blankets now.
"I tried to get some fire in my belly, but it was really difficult. I was a bit nervy the last couple of days, everyone is because you just want to get through.
"I will relax now and hopefully be better after Christmas."
Two-time winner Peter Wright crashed out after a 3-0 defeat to Jim Williams.
The 53-year-old, who was dressed as the Grinch complete with lime-green hair, ensured a miserable Christmas after posting a dismal three-dart average of less than 84.
Williams, a BDO runner-up in 2020, was also far from his best in a poor quality clash, admitting afterwards: "I was fighting myself all the way and it's a little bit frustrating – but hopefully we’ll get there."

A star was born earlier as 16-year-old Luke Littler marked his World Championship debut with a blistering 3-0 win over experienced Dutchman Christian Kist.
Littler showed no nerves as he hit seven 180s and finished with an extraordinary average of 110 to mark himself out as a genuine contender for the crown.
The teenager told Sky Sports: "I can’t believe how quickly I settled in. I was a bit nervous going to the stage but as soon as I found my rhythm, I was in."
Richard Veenstra eased past Ben Robb 3-0 while Ryan Joyce was a 3-1 winner over Alex Spellman.
