The Broncos No.7 laid on two tries for Selwyn Cobbo with pinpoint kicks and scored one of his own as Kevin Walters' men made it four wins on the trot.
Reynolds set the tone for the night when he clean bowled Tom Trbojevic with the kick-off to get the ball back for his team and two minutes later he set up Cobbo for the game's opening try.
The Sea Eagles launched an air raid of their own in the 14th minute when Tom Trbojevic flew high to bring down a Kieran Foran bomb and looked certain to score but desperation defence by Billy Walters denied the superstar fullback.
