The striker netted the Cherries first goal when he seized upon a wayward back pass and then late in the first half saw another effort saved, only for Marc Pugh to lash home the loose ball.
Speaking to afcb.co.uk, Grabban said that he was pleased with his predatory instincts and also with Pugh for carrying out what they work so hard for in training.
“You have to anticipate back passes all the time," he explained. “I was fortunate enough to be able to meet it and go through the keeper. It was a nice goal to score.
“It took the wind out of their sails and although they had possession, they never got any momentum.
“I thought I’d got a second, but it was a good stop from the keeper. It is part of Pughy’s job to follow up and it was great to see him get the goal.
“We work on that and I’m happy whoever scores as long as someone does, so that goal was just as pleasing as mine."
Grabban also highlighted the team’s professionalism following the challenge on Tommy Elphick, and the way they dealt with the often difficult task of playing a team who are a man light.
“As a group, we are very professional and we showed that. We had to put what happened in the back of our minds and take the opportunity to strike against ten men.
“The gaffer said at half time that we had to be aware that teams with ten men can be dangerous. We just had to keep doing the things that we are good at and work hard because that would pay off.
“They gave it a go which we expected, but we weathered that and from there on in, we were in complete control and the result was fully justified.”
