Two out of three again yesterday, this time it's a fourth day four-fold.
Steve Lennon v Callan Rydz - 19:15
Young guns battle to go the distance
Kicking off the action on day four of the PDC World Championship sees youngsters Steve Lennon and Callan Rydz duke it out on the Ally Pally stage.
Ireland's Steve Lennon makes his third consecutive appearance at the World Championship, and after a few years on the PDC tour, Lennon has established himself as a strong competitor, just outside the world's top 32 (37).
As for Bedlington's Callan Rydz, the youngster topped the PDC Challenge Tour after a consistently impressive season, impressive on the PDC pro-tour in the process.
This particular tungsten toss-up could well go close and in terms of the pairs performance levels over the course of 2019, Lennon's 3-dart average is superior to Rydz's with a 93.14 compared to 89.24, notably Rydz has competed in 19 more matches than the Irishman.
This will be a closely-contested battle and the over 4.5 sets market is most suitable for this one.
William O'Connor v Marko Kantele - 20:00
Consistency to prevail
It's Ireland vs Finland as William O'Connor takes on Marko Kantele at Ally Pally. For O'Connor it's been another successful year on-tour - winning a pro-tour event and reaching the last eight at the Players Championship finals in November.
As for Kantele, it's been a solid year on the PDC's Nordic and Baltic tour, reaching one final and a semi-final.
As performances on a consistent level are anything to go by, O'Connor should come through this one comfortably.
O Connor's performances in 2019 on-tour have been vastly impressive - averaging 93.56 over 59 matches, firing in 99 maximums along the way.
As for Kantele, he's had a steady season on the PDCNB tour - averaging 87.9, firing in 22 maximums.
For this one, the 180s handicap market is ideal, in favour of the Irishman.
Vincent van der Voort v Keane Barry - 20:45
Irish youngster to battle hard
As Irish youngster Keane Barry makes his debut at the World Championship, he's expected to impress pundits and fans everywhere.
The 17-year old is the third-youngest player to ever compete at Alexandra Palace and he's also the first player to play at Ally Pally twice in different events as the youngster will also contest the Junior Darts Corporation's World Junior Championship final against Adam Gawlas of the Czech Republic later in the week.
As for Vincent van der Voort, the Dutchman has enjoyed a solid year on the PDC circuit, reaching four quarter-finals and a semi-final on the European Tour with his run to the last eight at the European Championship being his most notable achievement this year - picking up £20,000.
As comparisons go in terms of form, the Dutchman has been consistently solid over the course of 2019 - averaging 92.96 over 78 matches, firing in 146 maximums.
As for Barry, he's had a great season on the PDC Development Tour - with an 89.58 seasonal average over 79 matches, producing 82 maximums.
The recommended market for this particular contest would be over 3.5 sets. Barry will certainly produce moments of class as will the Dutchman.
Gary Anderson vs Brendan Dolan - 21:30
Former Champion to find his rhythm
Two-time world champion, Gary Anderson makes his return to Alexandra Palace in the final game of the evening as the Scot comes up against Brendan Dolan.
Anderson's been out-of-sorts over the last year or so after battling a back injury. The Scot's only competed in a handful of events on-tour this season.
As for Dolan, the 'History Maker' produced an impressive display in his opening round win over Nitin Kumar on Sunday afternoon - wrapping up a 3-0 victory over the Indian-based player.
Both players have produced high-quality spells of form in terms of their seasonal averages. Anderson, although he hasn't played in a great deal of events this year, has an overall 3-dart average of 97.03 spread over just 27 matches, producing 73 maximums, which is an impressive statistic.
As for Dolan, the Irishman boasts a 94.51 average spanning over 58 matches, hitting 72 maximums.
As far as previous meetings go, the pair have met on 16 occasions with the shares spoiled evenly at 8-8. Although, Anderson has been victorious in their last three meetings. It's worth noticing that the pair haven't met since February 2017.
I feel that the number of maximums that Anderson's struck this year compared to Dolan, the Scot will hit maximums with more regularity than his Irish opponent.
