Sahibzada struck the first ball of the fifth over for a four, followed by a six off the second.
He took a single off the third to rotate the strike to Agha, who then dispatched the fourth delivery for a four towards the off side.
Agha ended up taking one risk too many, hitting the ball straight to the fielder and getting caught out.
Babar Azam walks into the middle.
Pakistan are 52-3 at the end of five overs.
