Pakistan endured a frustrating morning as it took them more than an hour and one ball short of 20 overs to capture the last two Zimbabwe wickets after the home side resumed at 235 for eight.
Junaid Khan took his fourth wicket of the innings when Prosper Utseya hooked a short ball to deep backward square leg after making a stubborn 22 off 82 balls.
Tendai Chatara and Brian Vitori added 46 for the last wicket, enjoying some fortune but seldom being threatened by some unimpressive Pakistan bowling on an easy-paced pitch. Cracks were visible on the surface but the bounce was mainly predictable.
Off-spinner Saeed Ajmal, who took 11 wickets in Pakistan's win in the first Test at the same venue, sent down seven overs without adding to his single wicket of the first day.
