Re: Pakistani pair in world record partnership..
I don't think you really understood the match. Although the Pakistan domestic structure is outdated, this match is not a symbol of that. Rather it is more of a better batting display from WAPDA. Also, Rafatullah is an afghan who apparently has pakistani citizenship. He most recently was barred from the ICC WC qualifiying rounds as part of the Afghan team.
Also, If you look at the scores, both teams batted well. Only thing, seems like Sui gas team did not a good bowling attack since they were not able to take wickets while the WAPDA team bowled Sui out for 466 on the same pitch.
