I hate bein out of position
 

I have AcAh in the SB of a party 100 6 max no limit. There are two limpers and I make it 7 to go. The two limpers call and the BB folds. I had ~100 to start, limpers have me covered.

FLOP- 7,9,4 (2 daimonds)

I bet out 20 and am min-raised by someone that I see as fairly passive. How do you proceed? Thanks in advance.
