A hat-trick from DEAN NYMAN boosted Redbridge's treble hopes as they hit first division high-flyers Brady for six at Fairlop.
Steve Summers, Daran Bern and Sam McCarthy completed the rout for the 10 men of RJC.
RJC manager Sam McCarthy told JC Sport: "It took us to the first half to get into gear. Although we had the majority of play in the first 45, we struggled to service the front men as quickly as we should have and this compromised us creating the chances.
"After going 2-1 up early in the second half, we found ourselves down to 10 men with Craig Sanford being red carded. The game started to open up at this point, fortunately in our favour.
"We dominated the second half and created some excellent football. Our pace up front proved to much for Brady and it was only a matter time before the gates opened."
Josh Rosenfield, the Brady manager, told JC Sport: "6-1, I think, flattered Redbridge a bit. We kept them at bay for about 65-70 minutes at 1-1 and we were well in the game. We approached the game well and tactically made it difficult for them to break us down. They soon when down to 10 men and we got careless with our approach. We went a bit more gung-ho and we got caught out a few times.
"We gifted Redbridge two or three goals with individual errors, but overall we can't be too disappointed. The difference between Premier League teams and Division One teams is when these guys, yesterday, were presented with an opportunity, they would take their chances.
"However, we will move on and have set our sights on promotion and playing teams like that week in, week out. I think with a full strength side we would have given them a better game and would have taken the game to them.
"They have quality all over and we wish them luck in the next round."
