ATs vs Open Shove with 1hand prev history

[SinkRox]

200nl 5max.

Just sat at table. First hand I see, UTG limps, and Mr X is in the BTN he pumps it up to $20.

This seems a bit overly frisky....

Then the next hand, UTG folds and Mr X now open shoves $175.

I have ATs in the SB.

I think this is the bottom of my range to call this likely maniac.

So I call with ATo+ and 77+ ...sounds good?
