Faisalabad: Zimbabwe's stand-in captain Hamilton Masakadza won the toss and opted to bat in the fourth day-night international against Pakistan at the Iqbal Stadium here.
The tourists, already without captain Prosper Utseya who failed to recover from an ankle injury for second match in a row, received a further blow when their paceman Tawanda Mupariwa sprained his ankle during practice on Tuesday.
Chris Mpofu replaced Mupariwa in the only change in the tourists' line-up.
Pakistan, leading 3-0 in the five-match series, made four changes from the side that won the third match by 37 runs at Multan on Sunday.
Opener Salman Butt, wicket-keeper Kamran Akmal, Younis Khan and Yasir Arafat made way for Khalid Latif, Sarfraz Ahmed, Fawad Alam and Sohail Khan as the home team attempted to try out more youngsters.
