The result sees the Trotters creep into the Championship playoff places with just two games remaining.
"We knew exactly the threats that Middlesbrough posed, that they would come at us down the wings with speed and would look to pass and move the ball in the midfield areas," the club's official website quotes Freedman as saying.
"Not only did we counter that successfully, but we pushed forward and caused problems of our own. We're playing very consistently right now and are hitting the form at the right time.
"We've got an away game now before we're back at the Reebok and we'll need them with again for the game against Blackpool."
Defeat leaves Tony Mowbray's men in 12th place.
