Sheffield Wednesday cruised to a 2-0 victory over newly-promoted Bristol City in Carlos Carvalhal's first competitive match in charge.
Second half strikes by defender Tom Lees and midfielder Lewis McGugan ensured the Owls claimed the spoils in front of a crowd of 23,255 at Hillsborough.
Both teams struggled to string anything together in the early stages.
Luke Freeman, the Robins' dangerman, cut inside from the left flank before dragging a shot well wide.
Marco Matias, one of five debutants for the hosts, mis-kicked a volley just before the half hour mark after neat approach play involving Atdhe Nuhiu, Alex Lopez and Ross Wallace.
Bristol City, who finished top of League One last season, occasionally looked threatening on the counter attack, with skipper Aaron Wilbraham shooting tamely at Keiren Westwood after a dangerous delivery by Joe Byran, who was later forced off with an injury.
Moments later, Matias latched on to Sam Hutchinson's raking crossfield pass but drilled an effort inches wide from an acute angle.
The best chance of the first half came in the 34th minute when Nuhiu's low cross was only partially cleared by Aden Flint straight into the path of Alex Lopez. With the goal at his mercy, the Spaniard's strike from 12 yards was deflected over.
City were mainly restricted to long range strikes. Both Marlon Pack and Jonathan Kodjia tried their luck from distance but failed to seriously trouble Westwood.
Wednesday broke the deadlock on the hour mark, Lees, who recently signed a two-year contract extension, rose highest to plant a bullet header past Frank Fielding after Alex Lopez's corner. It was Lee's first goal in Owls colours on his 49th appearance for the Championship outfit.
Things could have been so different had McGugan not hacked substitute Wes Burns' header off the line.
From the resulting counter attack, McGugan, captured on a permanent basis from Watford this summer, volleyed home from close range after a pin-point delivery by the lively Wallace.
Carvalhal gave a run-out to Lucas Joao in the closing stages and Matias lashed a shot over when well-placed.
In the dying minutes, Matias should have grabbed a third after a good move involving Joao and Kieran Lee but the Portuguese forward some how steered his left foot effort wide with the goal gaping.
