Second hand of a SNG

[flytrap]

This SNG is $80, and the winner gets a seat in a $650 buy-in wsop qualifier. This is the second hand, so everyone has 1500 in chips. Blinds are 10/20.
I'm dealt 7 5 in the sb. Late posistion limps, I complete, BB checks.
Pot is T60
Flop is 753r
I bet 60, bb makes it 300. What's my play?

It looks like he's trying to protect his hand. Most likely hands are A7 or a set of threes. Any 7 is the most likely and I think you push here.

Push.
