"It was a very physical game and they won the first half and we won the second in terms of physically. We weren't matching them physically and needed to step up and that is what we did.
"We knew at half-time that we needed to keep hold of the ball more as every time in the first half we got into their 22, we gave them the ball back softly and could never build momentum.
"We held on and got more clarity into our game. We managed to hold onto the ball and won more of the 50-50s and managed to come out on top.
"It was a great win and it meant a lot to the supporters, the noise out there was fantastic."
Results elsewhere saw Ulster climb into second place while the Ospreys are now third in the table after drawing with the Cardiff Blues.
The Blues, with a game in hand, are still very much in with a chance of a top four finish. The Scarlets' defeat in Belfast has probably left their fate in the hands of others.
The league now takes a break for a week, with the focus of Leinster, Munster and Ulster turning to the Heineken Cup and Amlin Challenge Cup quarter-finals.
But when the league returns, four of the top six teams will be in action against each other. Leinster will host provincial rivals Ulster on Saturday, April 16, on the same night that the Scarlets entertain table toppers Munster.
The Cardiff Blues and Ospreys are both away on Friday, April 15, taking on Connacht and the Newport Gwent Dragons respectively.
Munster apart, the competition for the remaining play-off places is so tight that the battle could go right down to the wire.
