Jimmy Calderwood said his side defended poorly

"I think were the better side in the opening 15 minutes, then we got a grip of it and started knocking the ball about," Calderwood told BBC Scotland.

"But there wasn't a lot of quality in the final third.

"It was quite even in the second half and I thought we had most possession. But a sloppy goal cost us and sometimes it's not going to be your day."
