The result ended a poor run of five matches without a victory and McCall said: "It's three points, three goals and a clean sheet and I'm pleased with that after the run we've had of late.
"We started brightly and I felt that it was important to get the first goal against a team struggling to find goals and we did that.
"Simon Whaley did well - he was a threat all night and we know he can do that. His touch in difficult conditions was superb and his goal was a great strike.
"We went back to a system that's tried and tested for us and it worked well. There's still a long way to go this season but we've moved closer to the top with a good win."
