Although Pakistan did not bat well yesterday but they have bowled very well and managed to take 5 wickets for South Africa cheaply. If they could make bowl out south africa quickly, they have a good chance to get hold of this test match also.
If Pakistan had managed to score in excess of 300, then I would have said that they have the advantage in this match. But they managed only 272. South Africa is not in a good state, but if they can score above 200, then the outcome will depend on the second innings. Pakistan is very inconsistent and I am not sure whether they will be able to get a good score when they come out to bat latter today.
BTW, Joe Root is batting at 154, with Ben Stokes giving him company. It is just unbelievable the way this guy plays. Back in Sri Lanka last month, he had scores of 228 and 1 in the first test, and then 186 and 11 in the second test. And once again, he is going to make a big contribution in this test match.
