You see as the output of the operation amplifier compensate the transistor effect until Vout reach the limit of the supply voltage - 2x Vbe 
If you reduce the input amplitude, you get a fine sinus output signal again

Your loosing the top and bottom of your wave. Increase the op amp dc supply and battery voltage to 12V

Yes I Know, you should decrease the input amplitude to be avoided as well, but on this input level can see the effect of the supply voltage limitation.

This means the maximum input voltage could be 4.1Vpeak

@PrathikP, you see the difference to your not working amplifier version. Here we have at the power stage no signal inversion while in yours we have, thats why yours is like a schmitt trigger while this one here is fine!
