Can he really be bluffing here? 2/4 NL

[DeucesNeverLoses]

8 handed 2/4 game, I have $440, both opponents have ~$300.

I am UTG w/ A[img]/images/graemlins/club.gif[/img] Q[img]/images/graemlins/club.gif[/img]. I raise to $16, middle position calls and BB calls. 3 to the flop:

A[img]/images/graemlins/heart.gif[/img] J[img]/images/graemlins/heart.gif[/img] 8[img]/images/graemlins/spade.gif[/img] Pot= $50ish

BB checks, I bet $30, MP pauses, then calls, BB calls.

A[img]/images/graemlins/heart.gif[/img] J[img]/images/graemlins/heart.gif[/img] 8[img]/images/graemlins/spade.gif[/img] 9[img]/images/graemlins/spade.gif[/img] Pot= $140

BB checks, I check, MP bets $60, BB grinds, then folds. Hero...?

I forgot to add the villain is new to the table. Only hands he has been involved in I've seen are he chased a flush draw down to the river against PSB's. Hasn't stabbed in position when I was in previous pots with him.

Fwiw, I am thinking to myself the only logical hands I can beat is AT, combo heart draw, or a weird bluff.
