After a slow opening 15 minutes, Hawthorn hit overdrive to grab a 22-point lead at quarter time. It helped that skipper Jai Newcombe threaded a classy 40m drop punt right on the siren.
The Hawks handed up three of the first four goals to the hard-tackling Suns, before wrestling back moment and kicking five straight.
Dylan Moore kicked two for the quarter and there were singles to Mitch Lewis, Blake Hardwick, Nick Watson and Newcombe.
Damien Hardwick will be perplexed. The Suns started on fire, bringing the heat and laying heavy tackles. Then they went missing.
