Tom Barkhuizen's goal early in the second half did the damage, after Josh Windass was sent off in the first half.
Here's how the players fared on the day...
1. Darnell Fisher - 7
A real outlet down the right hand side all game, including when he moved into a back three. His final ball sometimes liked that extra bit of finesse but showed his worth.
Tom Barkhuizen wheels away after scoring Preston's goal.
3. Patrick Bauer - 7
A solid showing from the German who provided a good foundation for the players in front of him. The Owls did try to cause problems, normally from set plays, and the defence stood strong.
4. Paul Huntington - 7
A number of key headers from set plays may have gone unnoticed but it's worth remembering it's a key attacking threat from a Tony Pulis team. Edges towards that 300 mark.
