Selected as an emergency for the clash against the Power, McKinley booted five majors in the Tigers' 47-point win to take his season tally to 29.
Hamish McIntosh was a solid performer in his return from injury, winning 17 hit-outs to go with his 14 disposals.
Also pleasing was the form of rookie Majak Daw who finished with 14 possessions and 24 hit-outs.
Ben Warren and Ben Ross were also prominent with two goals a piece.
There was some bad news on the day though with promising midfielder Matthew Scott sustaining a knee injury that forced him from the field.
