Pre-flop question

[rabbitlover]

MTT, this is live event. Only been at table for about 10 minutes.

Blinds are 100/200/25 9 handed, there is $225 in pot antes

I am SB with $5400
BB $7000
Button has $12400 and is table big stack.

Folded all around to button who makes minimum raise to $400

I have 9-7o in SB, I can only guess button is making a move, and I also guess that BB will call.

<font color="blue"> Is my hand worthy of making a $300 call into what I think will be an $1125 pot? </font>
