We got so much better - McKinnon
Manager Ray McKinnon praised the second-half improvement after Dundee United recovered to win their play-off quarter-final first-leg 2-1 at Greenock Morton.
Simon Murray and Blair Spittal were both on target following the interval to give the visitors the advantage going into the return meeting on Friday evening. Thomas O'Ware had headed their opponents into an early lead.
"We didn't really have any quality up top in the first half but it was a fantastic response in the second half," McKinnon told BBC Scotland. "We changed the system, got a lot of pressure on their back four and thoroughly deserved to win the game.
"In the second half the players were outstanding and we scored two really good goals," he added. "We deployed Simon Murray on the left in a 4-2-3-1 system but he didn't really have an impact on the game, so we put him up top and he made a real impact straight away."
