Not sure if Zimbabwe will lose by an innings as they will be taking their time batting to try and make Afghanistan bat again and maybe if they can get a small lead of say 100 runs, then it puts all the pressure back on Afghanistan to try and win the match. We don't see teams follow-on much anymore and to see Afghanistan ask Zimbabwe to follow-on shows that the Afghan team are confident they can get the job done and win the match.
Zimbabwe is still trailing by 234 runs. If they want to build a lead of 100 runs, then they need to make a total of 358, which looks very difficult. Both Rashid Khan and Amir Hamza looks to be in splendid form, and as match progresses, the surface will give more and more assistance to the spinners. In the first innings also, only Prince Masvaure and Sikandar Raza showed resistance against the Afghan spin bowlers.
