Thistle got 2014 off to a flying start with a dominant performance and defeat of Edinburgh University Reserves.
The first half was mainly concentrated in the middle of the park, with only Callum Heeps’ bullet freekick from 23 yards separating the sides at the break.
The second period saw many more chances created by Thistle, with four converted from various sources.
Heeps, Orr and McLean stretched the advantage before Heeps completed his hat trick with a cracking effort with the last kick of the ball.
The scoreline did not flatter the peformance of Thistle and provides a confidence boost ahead of the East of Scotland Cup challenge against a strong Stirling University next Saturday.
