3 handed 22

[citanul]

Friend and I are having a debate on the following hand:

We've just busted the 4th place player.

Hero is on the BB, which is about 4 hands into 250/500 blinds.
Next hand Hero will be the button. (short stack will be sb, big stack will be bb.)

Button has 5550, UTG has 2200, Hero has 2250.

UTG folds, button pushes, Hero has 22.

Hero?
