Alastair Clarkson said the Hawks were simply beaten by a better side on Saturday night.
St Kilda led from start to finish, recording its third win of the season against a disappointing Hawthorn outfit.
Clarkson said the Saints put together one of their best performances of the season against the Hawks in Round 7.
“We’re disappointed when you lose by 10 goals, but you’ve got to give credit to the opposition, they were pretty good,” Clarkson said.
“We lowered our colours to a good side. We lowered our colours to a really experienced and strong St Kilda side in that space.
"The opposition we're pretty good. Probably for the competition, they haven't see the Saints like that for the year.
"It isn't meant to be a slight on them but they're a very, very capable side and I don't know the reasons why they haven't been playing to the level they produced today."
