A Sam Baldock penalty has cancelled out Miguel Llera's opener as Sheffield Wednesday and Bristol City go into the break with the score at 1-1 at Hillsborough.
The hosts got off to the perfect start when Llera turned in a corner to put the Owls ahead inside four minutes.
The Spanish defender nearly doubled his side's lead a few minutes later, but his low 25-yard free kick was stopped by Tom Heaton.
Wednesday continued to control the match, as Gary Madine saw his effort smothered by Heaton.
Despite their early dominance, the home side were pegged back when Baldock successfully converted a City penalty after he was brought down by Llera.
Chris Lines then went close to putting Wednesday back in front, but his shot was blasted just wide after a knock-down from a long ball.
