The Sydney Swans reserves have booked their place in the NEAFL Eastern Conference Grand Final with a commanding 81-point win over Belconnen in Saturday afternoon's 2nd Semi Final.

In warm and sunny, but breezy, conditions at Blacktown Interntational Sportspark, the Swans were never headed as they controlled the match from start to finish to secure a spot in their third successive conference decider.

Jed Lamb, who returned to the reserves line-up after being the sub in last week's senior loss to Geelong, got the team off to a flying start with two first quarter goals and plenty of run and carry through the middle of the ground. Such was Lamb's impact to start the game that Belconnen moved their captain Lexie Bennett on to Lamb to play a run-with role on him.

In his first final for the club, Tim Membrey showed that he could be a future big game player, finishing as the leading goal kicker on the ground with six majors, as well as providing a leading option off the half-forward line and assisting multiple goals for his team mates.

All eyes at Blacktown - including those of senior coach John Longmire - were on Lewis Jetta, who was playing his first competitive game since the start of June.

Jetta - who played for the Swans in the inaugural Eastern Conference Grand Final in 2011 - finished the game early term after getting some run into his legs and showed brief glimpses of form including a running, long-range goal from outside 50 which was one of his last involvements in the match.

The Swans midfield, led by Lamb, Daniel Robinson and Jake Lloyd, were outstanding for the majority of the match and fed on first use of the ball provided by ruckman Sam Naismith.

In just his second game for the season, Naismith showed he will be an important player as the finals series progresses, finishing the game off well with two goals from contested marks late in the final quarter.

The Swans defence was rock-solid all game, and save for a ten minute period in the third term, restrict Belconnen's ability to kick consecutive goals and build any momentum. Tony Armstrong was one of the standouts as a rebounder from defence, while the key posts of Xavier Richards and Jordan Lockyer, supported by top-up Stephen Wray, shutdown the highest scoring offence from the home and away season.

The contribution of the top-ups was significant, with seven of them featuring on the goal kickers list, with Lloyd Perris leading the way with two, including a fine effort after accelerating through a pack and bouncing one home from just inside the 50 metre arc.

The Swans reserves will again have a week off next weekend and will play the winner of the preliminary final between Belconnen and Ainslie in the Eastern Conference Grand Final, scheduled for Sunday August 15.
