Lawrence Shankland has now scored 17 goals this season

Ayr United are two points clear at the Scottish Championship summit after trouncing Morton at Cappielow.

Ayr scored four goals in 16 second-half minutes after Ross Doohan conceded then saved Michael Tidser's penalty.

Lawrence Shankland netted twice to take his season's tally to 17. Craig Moore also scored a double, with Declan McDaid completing the rout.

United are two points above Ross County after seven games. Morton, who scored through Charlie Telfer, sit sixth.

Ayr United manager Ian McCall: "Ross saves the penalty which he gave away with a great save and after that, every time we got up the park, we looked like scoring goals.

"We got five and should have scored more. I don't know what team to pick next week against Dundee United - the real pleasing thing for us today was that a lot of boys got on who hadn't had a lot of game time and showed they are totally and utterly ready to play."

Morton manager Jonatan Johansson: "It was really poor defending. We capitulated after they scored their second - it's unacceptable.

"We completely lost our shape. Ayr play their system very well, work really hard and have two really good strikers. But up until the second goal we handled it quite well."
