Reigning world champion Luke Littler started his Bahrain Darts Masters defence with a 6-3 victory over Lourence Ilagan to book his spot in the quarter-finals.
Littler is looking to keep hold of what was his maiden title on the PDC circuit, just a couple of weeks after he was crowned the youngest world champion at Alexandra Palace at just 17 years of age.
It is also the tournament at which he hit a nine-darter against Nathan Aspinall in the 2024 quarter-finals, his first of four across the year.

The 'Nuke' was in control throughout his opening encounter at Bahrain International Circuit and managed to survive a mid-match fightback from Ilagan, a silky 142 checkout plus two breaks of throw helping him to wrestle back the momentum.
"It felt good and I'm just happy to get past that first game," Littler said. "I played alright in patches and did the right things at the right time.
"It would mean the world to come back and retain this title. I know it will be a long night tomorrow but I'll be up for it."
Littler will now face Gerwyn Price who put in a solid showing with a 6-3 victory over Ally Pally crowd favourite Lok Yin Lee.
The other big story of the night saw Paolo Nebrida put his name in the record books as he became only the second player from the Asian Tour to beat a PDC player on the World Series with a 6-3 win over Rob Cross.
Cross looked out of sorts and had a terrible time on the doubles, a break of throw and loss in a 29-dart leg setting him back to 3-1.
From there, Nebrida did the tough work and a clutch 116 checkout was followed by 62 on tops for a game-winning break of throw which awarded the Filipino player his own slice of darting history.
"I'm proud to win and I know there's more to come," Nebrida said. "I felt good but Rob is a tough player. The 116 was important and when my first dart goes in, I have a chance."
World No 1 Luke Humphries put in a stellar performance as he cruised to a 6-0 win over Abdulla Saeed.
Humphries came out ready to entertain the crowd and his checkouts of 151, 100, and 141 did just that, 'Cool Hand' hitting 180s with ease on the way.
Fourth seed Stephen Bunting booked a quarter-final showdown against Chris Dobey with a 6-2 domination of Nitin Kumar.
Bunting came out firing, 142 and 122 checkouts plus three big breaks of throw helping him take control and send out a statement that his form is not going anywhere after his run to the semi-finals in the World Darts Championship.
Dobey also made his mark with a 6-0 whitewash win over Basem Mahmood, while Peter Wright put in the work early on to cement a 6-3 win over Alexis Toylo and make it through the first round - where he will face Nebrida - for a third year in a row.
The final match of the evening saw Nathan Aspinall put in a professional performance to wrap up a 6-2 victory against Xiaochen Zong.
