The Scotland striker stole the show at London Road as Rovers jumped into the top six while sending their sorry hosts tumbling to the bottom of the npower Championship table on goal difference.
Mauro Formica opened the scoring before Rhodes took over the scoring duties with two before the interval and a third 11 minutes from time. A delighted Berg said: "It was a fantastic feeling to see my team produce a performance like that.
"Crystal Palace had needed two very late goals to beat Peterborough and Brighton had to score in injury time to do it, so going in front so early was key. The difference between that display and our previous games was the quality of our play in the final third.
"We already know Jordan is a great finisher and he proved that again. He did brilliantly in League One last season and is already doing well in the Championship. Hopefully next season he will be in the Premier League with Blackburn.
"Providing we feed him with opportunities he will score lots of goals. It was a shame we conceded a late goal as that stopped it being a perfect day."
