GREENOCK Morton boss Jim Duffy said he wants to make more use of striker Frank Ross after his "terrific" performance helped the Championship side into the Scottish Cup quarter-finals with a 3-0 victory over Dumbarton.

Ross put Morton ahead on 12 minutes after combining with Gary Oliver in a slick one-two move before Jack Iredale doubled their lead early in the second half. Substitute Bob McHugh put the tie to bed with 10 minutes to go as he got on the end of Ross’ cross with a sublime first-time volley.

It was Morton's fourth win on the trot in all competitions and Duffy said Aberdeen loanee Ross, who played in all those victories, was proving to be a star player.

“Frank was terrific," he said. “He was a joy to watch and it’s like with any flair players you need to get them on the ball more so we still need to work him into the system that we play.

“We’re into the quarter-finals and that’s something to look forward to for the players.”

Dumbarton were hoping to get revenge on Morton after the Greenock side sent them out of the cup in 2010. They did show attacking promise in spells but struggled to create many clear-cut chances against the hosts who were oozing with confidence.

Dumbarton manager Stevie Aitken said they must pick themselves up quickly with their Challenge Cup semi-final against The New Saints on the horizon.

“We can’t feel sorry for ourselves," he said. "We’ve got a semi-final next week and our league campaign is still going OK so we’ve just to keep going.”

Cove meanwhile, lost 3-1 to Ladbrokes Championship side Falkirk with Alex Jakubiak scoring a double.

Jakubiak gave Falkirk the lead in a frantic start at Harlaw Park with a goal after two minutes but Cove's Mitchel Megginson replied within a minute. Falkirk went back in front just after half time through Craig Sibbald with Jakubiak grabbing his second two minutes later as they took control of the game.
