Laws: Keogh responded perfectly
"Andy has responded perfectly to being left out of the team," said Laws.
"He may not have liked the decision but he understood why. The goal will be a terrific boost to his confidence and underlines the strength in depth that we now have in our squad.
"It was another terrific home performance by us and how Billy Sharp failed to get onto the score sheet I just don't know.
"He had numerous chances to hit the back of the net but just could not find his finishing touch. The result gives us back-to-back home wins for the first time this season and lifts us towards a mid-table position.
"Now we have got to see if we can produce these kind of performances away from home."
Cheltenham boss John Ward was disappointed, but admitted the Iron were good value for the win.
"To be honest it was a difficult game for us. Scunthorpe put us under a lot of pressure," he said.
"They were the better side but we dug in and defended well. I can have no complaints about the effort or commitment from my players.
"We can take a lot of positives from this game. But it is still a learning curve for us in this division this season."
