Azhar Ali of Pakistan scored 302 not out against West Indies in the ongoing test at Dubai-DSC to provide the second occasion of a Pakistan opening batsman scoring 300 plus runs in a test innings. Both occasions are listed below chronologically. By an interesting coincidence both the Pakistan batsman have chosen West Indies as their opponent while accomplishing the feat. It took 58 years for Azhar Ali to emulate Hanif Mohammad in scoring a triple hundred

No	Player	Runs	Inns	Team	Oppn	Ground	Start Date
1	Hanif Mohammad	337	3	Pak	Win	Bridgetown	17 Jan 1958
2	Azhar Ali	302*	1	Pak	Win	Dubai (DSC)	13 Oct 2016

One more coincidence that is noted with interest is that when these two Pakistan opening batsmen scored triple hundreds, their opening partners were dismissed in nineties. When Hanif Mohammad scored 337, his opening partner Imtiaz Ahmed was dismissed for 91 against West Indies at Bridgetown in Jan 1958. When Azhar Ali scored 302 not out, his opening partner Sami Aslam was dismissed for 90 against West Indies in the ongoing test at Dubai-DSC in Oct 2016
