Tim Visser, Matt Scott and Stuart McInally all crossed for the Scottish side in Galway, with Jason-Harris Wright and Danie Poolman touching down for the hosts.

Greig Laidlaw provided the assists for the Scott and McInally tries, in addition to his kicking haul of three conversions and a penalty.

Former Scotland out-half Dan Parks, who finished with 13 points, had a late chance to win it for Connacht but his drop goal effort shaved the right hand post.

One of Edinburgh's five returning internationals, Visser, swept through for a typically opportunist try inside the opening five minutes of this incident-packed encounter.

A poor pass from Parks put centre Poolman under pressure, the grounded ball was hacked on and Visser nudged it on further - 30 metres out - to get his 10th try in this season's RaboDirect PRO12.

Connacht were beaten by the Scotland winger's searing pace and Laidlaw followed up with an accurate conversion for an early 7-0 buffer.

The scores came thick and fast in the opening quarter, Connacht hitting back after a Parks cross-field kick was taken into touch by the covering Tom Brown.

From the resulting lineout, the hosts worked a well-executed drive and young hooker Harris-Wright plunged over for his first league try. Parks' conversion brought Eric Elwood's charges level.

Some of that good work was undone though when Connacht infringed straight from the restart, allowing Laidlaw to kick the Scots back ahead.

Although Edinburgh had the better of possession, they lacked the territory to hammer home that advantage and Michael Bradley's men had to bide their time against an energetic Connacht defence.

The excellent Eoin McKeon and Michael Kearney typified the effort of a Connacht pack missing the likes of John Muldoon, George Naoupu, Michael Swift and Mike McCarthy, who was Ireland's man-of-the-match against South Africa.

Parks made it 10-all with a 17th minute penalty, however the hosts were left reeling when captain Gavin Duffy was forced off with a knock - adding to an injury list which numbered 17 pre-match.

Edinburgh swooped for their second try closing in on the interval, industrious number 8 McInally securing clean lineout ball and Scott scoring off Laidlaw's well-weighted chip through.

Laidlaw's conversion was cancelled out by a late penalty from Parks, who rewarded prop Brett Wilkinson for winning a scrum decision.

17-13 in arrears at the break, Connacht almost handed Edinburgh a 'soft' try in the opening minutes of the second period.

Parks was swarmed over as he attempted a drop goal, it was blocked and McInally showed great pace to press forward. The breakaway ended with Scott knocking on close to the line.

Parks lifted the westerners with a 58th minute penalty, but Edinburgh continued to show more of a try-scoring threat. Replacement scrum half Chris Leck was unfortunate to fumble after a sparkling three-man break.

Young full-back Robbie Henshaw did well to stop David Denton on another dangerous attack, yet Edinburgh's persistence paid off when Laidlaw's inside pass put McInally over for a deserved score.

The conversion was good although Connacht had Edinburgh sweating in the final minutes. The home side lifted the tempo with Henshaw, Tiernan O'Halloran and Fetu'u Vainikolo all coming alive in attack.

A slick back-line move, with Henshaw cutting a very good line, ended with Poolman scoring out wide. Parks swung over the conversion in superb fashion to make it a one-point game.

The ensuing 10 minutes saw proceedings swing in Connacht's favour, but they failed to muster a match-winning score with Parks' drop goal attempt the closest they came.
