Interesting Tourney Hand

[pgec311]

Last night playing in a Headhunter tourney on JSP. These tourneys I play mainly for fun, usally 200 to 250 players, I won the night before so I thought I would go for back to back. Anyway, second hand blinds 10/20 and I am in the BB with AJo. Folded around to the sb who raises to 60. I flat call. I will go ahead and admit that I played this hand pretty passively. Flop comes 4d As 7s. sb bets 80. I just call again here. I really don't think he has a hand at this point and I want to see if I can get one more bet out of him and raise on the turn. Turn is the 6c. SB goes allin...
What do you have him on here and what is the play.
