The home side offered a huge aerial barrage to the Owls, who defended diligently and would have been well worth a win after Julian Borner netted his first goal for the club.
But who else were the star men on the day and who was below par? Take a look at our player ratings from the Welsh capital.
9. Massimo Luongo - 6
A rare quiet showing from Luongo, who worked hard as ever but couldn't quite get into the game as much as so many of his teammates. Wasted a great chance to make it two on 48 minutes. Photo: Steve Ellis
10. Kadeem Harris - 8
Back at the club that let him go for nothing in the summer, the boy done good. His pace frightened the life out of Cardiff all evening and it was his shot that Borner deflected in. Hit the bar from a free-kick, too. Photo: Steve Ellis
11. Steven Fletcher - 6
It was always going to be a fascinating aerial battle as Fletcher went up against Aden Flint and Sean Morrison. The bout was drawn, you feel, but Fletcher battled hard. Photo: Steve Ellis
