Is this callable?

[Niwa]

Prima 1/2

Hero: ~$250
Villain: ~$200

I get A [img]/images/graemlins/spade.gif[/img]K [img]/images/graemlins/heart.gif[/img] on the button.

Preflop: Villain raises to $10 (5xBB), I call.

Flop 9 [img]/images/graemlins/spade.gif[/img] T [img]/images/graemlins/heart.gif[/img] x [img]/images/graemlins/club.gif[/img], check, check
Turn: A [img]/images/graemlins/heart.gif[/img], check, I bet 2/3 pot.
River: A [img]/images/graemlins/club.gif[/img], all-in, fold.

Anyone call that river? Its the first good hand I pick up in a long time and I have no reads whatsoever on villain but he seems decent.
