Greenock Morton leapfrogged Raith Rovers into the Scottish Championship playoff places after beating Queen of the South 2-0 this afternoon for their fourth successive win.
It was the visitors who looked most likely to open the scoring following a timid start, and their best chance came on 23 minutes when goalkeeper Grant Adam kept out Derek Lyle.
Ross Forbes came close for the hosts when his sneaky free kick was beaten away at the near post as both sides settled for a share of the spoils in an evenly fought first half.
Morton emerged from the break reinvigorated and it took only six minutes for Jim Duffy's side to move ahead.
Good work from midfielder Michael Tidser set up the chance as Johnstone beat his marker, before curling home from 20 yards to open the scoring in style.
Johnstone doubled the lead on 62 minutes by smashing home from a corner as the Ton took a big step toward making it four wins on the spin.
The hosts were unduly untested at the other end, but Swansea City loanee Alex Samuel almost made it three, though his late effort fizzed wide.
