Keith Millen secured his first win as Bristol City manager in what may be Nigel Adkins' last match for Scunthorpe.
Adomah and Clarkson secure City's first win of the season
Keith Millen secured his first win as permanent Bristol City manager in what may prove to be Nigel Adkins' last in charge of Scunthorpe United.
The Robins turned to Millen to replace Steve Coppell just a couple of games into the new season and he has had to wait for his first three-point haul.
Albert Adomah set the visitors on their way at Glanford Park with a 16th minute opener before substitute David Clarkson made certain of the victory in the final minute.
Whether or not it was Adkins' final game at the Scunthorpe helm remains to be seen as he has held talks with Southampton over the vacant managerial position at St Mary's.
The Iron were unchanged from the side which beat Crystal Palace on home soil a fortnight earlier.
Midfielder Cole Skuse was recalled to City's starting line-up after a knee injury and replaced Ivan Sproule on the left-hand side of midfield.
Scunthorpe began the brighter and could have led inside the sixth minute when Jonathan Forte crossed dangerously and Sam Togwell connected with a superb 25-yard volley which David James tipped around a post.
In the 15th minute, the Iron went close again as midfielder Michael O'Connor curled a delightful shot goalwards from 25 yards but the ball narrowly missed the target.
Yet two minutes later City led when Brett Pitman collected possession and provided a fine pass to Adomah, who rifled a right-footed shot into the bottom corner from 12 yards.
Injury blow
Scunthorpe were dealt a blow soon after when defender Rob Jones succumbed to injury and was replaced by Niall Canavan.
In the 25th minute, Eddie Nolan crossed dangerously but Damion Stewart produced a fine clearance.
Moments later Jon Stead hit a fine shot from 30 yards which David Mirfin did well to block.
Yet the Iron continued to probe and were almost rewarded in the 33rd minute when Collins had a fine long-range effort saved by James.
Two minutes later, Pitman fired wide when he should have done better.
Stead then had another effort blocked by Mirfin and Marvin Elliott headed a cross from Nicky Hunt straight at home goalkeeper Joe Murphy.
Four minutes after the restart, Chris Dagnall mis-hit a long-range shot and team-mate Josh Wright fired over from 25 yards.
In the 54th minute, Sproule replaced Adomah and Collins then had an effort saved by James.
Three minutes later, Wright crossed dangerously and Cliff Byrne connected sweetly only for his effort to be blocked by Liam Fontaine.
In the 62nd minute, Stead crossed for Pitman to fire straight at Murphy from 12 yards.
Chances continued to come and go but Scunthorpe could not find a way through as City held firm.
They claimed their second goal in the fifth minute of added time when Clarkson collected a pass from Stead and rifled home from 12 yards.
