Rate this play, A9o

UB $200+15 ($120k guaranteed). Started w/ 561 players, top 60 pay.

75 people left, avg stack is about t16,000, I have t10,700. Blinds are 400/800 w/ 100 ante (2200 in each pot pre-deal). I just got moved to this table about 12 hands ago.

A note about the BB: right when I got moved to the table, he was in a hand all-in, but I didn't catch the action, though he didn't show when the other guy folded. The next hand I played I was on CO, I raised first in, he pushed I folded. I'm pretty sure I saw one more aggressive action before the flop, but I still haven't seen him showdown.

This hand I'm in the SB w/ A9o and t11,700. Everyone folds to the button who limps. I raise to 3000 and the BB pushes on me, he's got about t18,000. Button folds. I call.

Bad move?

I don't know much about him, but I got a strong feeling like he was making a play at me. Is A9 strong enough to call here? I'm getting like 16:7 ~ 2:1 chip-odds.
