The leadership and poise of flyhalf Angus Sinclair help steer Northern Suburbs through a number of hurdles on their way to a 40-26 win over the Western Sydney Two Blues on Saturday.

The Two Blues actually scored the first try of the fixture and showed some genuine promise at different times of the game in the Southern Highlands of NSW but in the end Norths scored six tries to four.

Sinclair was able to turn the big Two Blues pack around and gave Norths a major advantage in territory at critical times.

He also converted five of Norths' six tries in what ended up being quite a fine all round display.
