Whats my best river action here holding TT

[mackthefork]

Villian is 73/32 with postflop aggression of 1.05 over a short sample ~200 hands. Is there anything I can do other than calling the river I mean if he was on 78 would he not raise on the turn, and what are the chances of him having a 9 really? How often does he put me on two overs and bet his small pair thinking he's got the best hand? Is a raise/fold any good?
