St Mirren eased to the fifth round of the Scottish Cup with a win over Brechin City.
The first real chance fell to Kenny McLean after 19 minutes, hitting a shot from 25 yards that was well parried by Brechin goalie Craig Nelson.
But the midfielder opened the scoring on the half hour from a free-kick at the edge of the penalty box.
The home side consolodated before the break, Jon Robertson striking with a volley from 35 yards from a corner.
Saints dominated possession early on but were restricted to a number of long range efforts from midfielder McLean that were easily dealt with by Nelson.
McLean was pulling the strings for the home side and came close to opening the scoring after 19 minutes.
A cross came in from the right hand side and McLean fired in a shot from close range but Nelson once again saved low down.
The breakthrough came on the half-hour mark and it was the danger man McLean who found the net.
It was free-kick on the edge of the box and this time Mclean was able to find the corner of the net with a curling left-footed shot.
The twenty-year-old has been touted for a move away from St Mirren in the January transfer window and, if he continues in this form, there are sure to be many clubs interested in securing his signature.
Brechin were forced into making a change before half time as Jonathon Brown hobbled off and was replaced by Jonathon Stewart.
On a rare venture upfield City striker Kurtis Byrne had an opportunity from the angle of the box but the former Hibs player fired high over the crossbar.
Just four minutes before the break the home side doubled their advantage with a terrific goal.
A corner was played backwards to midfielder Jon Robertson who volleyed the ball beyond Nelson and into the net from fully 40 yards out.
The second half began with the home side again dominating proceedings.
Kenny Mclean picked up the ball 25 yards out but his left-footed drive was narrowly over the Brechin crossbar.
Then, Nelson tipped over another McLean effort from a similar distance, this time frmo his right foot.
Dougie Imrie had replaced John McGinn at the break and he almost made it three for Saints with a curling shot that was narrowly over the bar.
Brechin were offering very little by way of a threat to the home goal, but when they did venture forward the Saints back line stood firm.
Lewis Guy then went close when he latched onto a ball at the back post and was inches away from finding the target.
The 220 Brechin fans who made the trip had little to cheer about on a cold Saturday afternoon in Paisley.
And the three-time winners of the trophy easily secured their passage into Mondays fifth round draw.
