The outside-half racked up all his side’s points – including two tries.

Man of the match Parks completed a complete set of scores by adding both conversions, a penalty and two snap drop goals to kill off the capital men. Edinburgh had made the most of the hosts’ jitters by surging ahead in the fourth minute.

Ben Cairns made the initial break, leaving two markers for dead, before sending Andy Turnbull over in the corner. Phil Godman’s wide-angled conversion dropped short off the crossbar.

Rattled Glasgow burst back immediately thanks to the fired-up Parks.

The Edinburgh defence raced forward too fast, allowing the Scotland playmaker to dash through a half gap for a brilliant solo touchdown.

He followed up by slotting the extra points to put his side in front.

The frantic end-to-end action continued with Cairns again underlining his pace and power to get to within a couple of paces of the target.

The centre could have claimed the glory himself, but unselfishly tried to unload the ball in contact, only for it to dribble forward.

Gunners kept up the momentum and their efforts were rewarded in the 27th minute when Godman confidently banged over a 40-metre penalty.

Glasgow rallied close to the interval and they snatched back the momentum as Parks landed an opportunist drop goal.

But there was still time for Godman to repair the damage with his second penalty which paved the way for a tense second half.

There was another dose of frustration for the home troops within seconds of the restart when Parks sent his next shot at goal wide of the target.

And there was a further let-off for the Gunners as another drop goal bid by Parks was blocked by Matt Mustchin.

The stand-off’s luck took a turn for the better three minutes later when he stroked over a penalty.

Play was still sweeping from end to end and Edinburgh instantly powered back into the attack.

Godman re-entered the penalty duel with Parks and completed his treble to grab back the lead in the process.

Both sides made a spate of substitutions in their quest to rule the crucial final 15 minutes.

And it was Glasgow who struck next with another top-notch score, thanks again to Parks.

The number 10 launched the move and finished in style following great link work by John Barclay and Max Evans.

He then had the home fans on their feet by banging over the conversion to open up a six-point advantage with 10 minutes left.

Even better was to come from Parks when he notched his drop goal double.
