Stuart McCall was pleased to see his side carry out a professional job on their Scottish Cup opponents from the First Division. The stuffing was knocked out of Morton in the first half as Motherwell ran up a 5-0 lead before getting a sixth and final goal in the second half. This win and other cup results could also help them win the battle for third place in the SPL. While Motherwell's name will be added to the Scottish Cup draw on it's own, fellow SPL sides St Mirren and Aberdeen will have to win replays if they are to book a place in the last eight. The Fir Park side stunned their visitors as Tom Hateley scored directly from a corner before Jamie Murphy, Shaun Hutchinson, Henrik Ojamaa and Nicky Law all scored before the break. Murphy then blasted home his second goal midway through the second half to complete a one-sided scoreline. McCall said: "Hopefully having to play one game less than our opponents will give us a little edge over them when we meet in the league. It was a professional job, we asked at the beginning of the game for a high tempo as we couldn't afford to go out and take liberties or we would be in for a rude awakening. I am delighted that we have been able to address our poor home form in recent weeks. We had a team meeting and discussed three massive home fixtures, it is very pleasing that we have managed to win all three and score 12 goals in the process." McCall was delighted to see the goals shared around the team as Motherwell won their last three home games. He said: "I have been looking for Nicky (Law) to add goals to his game and he has now scored two in our last three games. It was also good to see Shaun Hutchinson score, he regularly goes up for corners and we spoke to him about getting on the end of them more regularly." Morton manager Allan Moore was disappointed that his players did not carry out individual instructions discussed ahead of the game. He and his staff now have to pick them up after slumping to a heavy defeat. The First Division side were unable to cope with Motherwell's attacking threat and speed in the first-half at Fir Park. Moore said: "I thought this could have been a real morale problem for our league campaign. We took a big support with us to Motherwell and certain individuals let us and them down. We must pick ourselves up quickly from what was a painful day for everyone."
