TT bottom set...awkward river

[DrPublo]

PP 200NL 6max.

Villain seems pretty passive. Only hand we have played togther: I raise in the CO with AJ, he calls on the button. Flop is 235 all spades (I have none). I bet pot he calls. River is offsuit 4. I bet half pot he calls. River is offsuit ace. Check, check and he shows 99.

In this hand, he calls quickly on the flop and turn, making me think he's calling down but the river may very well have helped him.
