Phil Taylor and Dave Chisnall face a potentially make-or-break night in terms of their Premier League Play-Off aspirations as they get set to contest two matches in Belfast on Thursday.
The race to secure Semi-Final places is heading for a fascinating finish with just four weeks of round-robin fixtures remaining before Finals Night at The O2 in London.
Just one point separates the players positioned from third to sixth in the league table, though four players still have game in-hand on their rivals.
They include six-time Premier League champion Taylor, who looks to climb in to the all-important top four following his two fixtures at The SSE Arena this week.
Taylor starts the night on 13 points, one adrift of Raymond van Barneveld in fourth, and faces a crucial opening clash against two-time Premier League winner Gary Anderson.
The duo played out a gripping 6-6 draw in the reverse fixture last month and could be poised for a similarly close-run battle this time around.
Anderson claimed three points from a possible four in Liverpool last week and will be keen to pick up from where he left off in a 7-2 rout of Peter Wright - averaging 113 in the process.
The world number two has failed to defeat 'The Power' in their last four Premier League meetings, but ending that run here could see him take a huge step towards securing his play-off spot.
Taylor will return later in the evening to take on rock bottom Chisnall - who knows he must realistically take maximum points from his two matches if he is to have any chance of gatecrashing the top four.
Chisnall is two points adrift at the foot of the table but is no stranger to picking up points when needed, having claimed back-to-back triumphs in Exeter earlier in the season to stave off elimination.
Chisnall's first test comes against another Stoke great in Adrian Lewis - who lit up Liverpool with a sensational nine-dart finish in his victory over Van Barneveld last Thursday.
Lewis is now just one point adrift of fourth spot and with a game in-hand, but after suffering an early exit in the German Masters over the weekend, will be determined to return to winning ways here.
Five-time World Champion Van Barneveld marks his 50th birthday with a mouth-watering all-Dutch show-down with reigning champion Michael van Gerwen in the pick of the night's matches.
Barney hits the bullseye in Belfast and will be doubly-determined to celebrate in style by denying his nemesis all two points in what promises to be a special occasion.
Van Barneveld is the only player to claim victory over MVG this season, having done so in Manchester a month ago, but will drop out of the play-off places if the world number one can return the favour.
League leader Van Gerwen battled back from 5-1 down to salvage a 6-6 draw with Peter Wright last week, before going on to lift the German Masters title for the third consecutive year on Easter Monday.
The night's other contest sees world number three Wright taking on James Wade - who defeated the colourful Scot en route to the Semi-Finals of the German Masters earlier in the week.
Wright is sitting pretty in second spot and knows that one final push is required to secure his place in the final four for the first time.
Wade, meanwhile, is second from bottom, four points adrift of the play-offs, but victory over Taylor last week and his run to the last four in Jena will have injected a timely confidence boost.
The action gets underway from 7pm BST, with all matches to be contested over the best of 12 legs, making a 6-6 draw a possibility. Two points are awarded for a win and one for a draw.
