The top five in the Group 6 first grade comp has been finalised for 2019 following a dramatic round of football.
The Oaks Tigers and Oakdale Workers both secured important wins in round 17 action.
The Tigers proved too strong for a young and competitive Mittagong Lions side, winning 48-10 on Sunday at Mittagong Sportsground
The Lions started well through Blake Jeffrey, who scored a nice solo try from dummy half. Mittagong led 6-0 after 18 minutes in a rare highlight for home supporters.
The cool and blustery conditions made life difficult for the outside backs.
However, the Tigers' Mitchell Brasington mastered the weather conditions well and caused havoc for the Lions.
Ben Scambary, who played in the back row, finished with a double as the tries flowed for the visitors after the 30-minute mark.
The Tigers crucially scored tries either side of the half-time break, and added three more tries in an eight-minute period to blow the game wide open.
Brasington was accurate with his goal kicking, landing all eight attempts at goal in a personal haul of 16 points.
The Tigers cleared away from the Lions, who could only manage one try after half time.
The win sees the Tigers book their own finals berth.
Narellan can't reach the finals, even if the side secured a win on Saturday night in the final round.
Brasington, along with brother and co-coach Matthew, would be happy with how the Tigers are firing ahead of the finals.
The Oakdale Workers also won their their way into the finals following a 29-16 win over the Narellan Jets on Saturday night. The match was effectively a sudden-death playoff at Sid Sharpe Oval.
The Workers sprung out of the blocks to score two tries inside the first 10 minutes via Beni Nawai and Alec Bush.
Matt Jones then scored a well-deserved solo try to extend Oakdale's advantage to 14-0.
The Jets then started their comeback through a try to Hakaraia Toi Toi.
The Workers held a 16-6 lead at half time.
Jackson Kuli gave the Narellan supporters hope with a try just after the break.
However, that was a long highlight for the visitors as Oakdale kicked into gear.
Tries to Arthur Little and Jake Steadman sealed victory for the Oakdale, before Leon Longbottom scored a consolation try for Narellan.
Little then kicked a field goal in the final minute to seal the 13-point win, and to book a place in the finals.
