His bowling performance of 4 wickets for 9 runs in 4 overs was amazing and clear sign of his talent especially when other bowlers were struggling. You also made key point about Pakistani cricket finding consistent world class spinner since eras of Saqlain Mushtaq and others. Abrar represents huge hope for filling that role. As you said his biggest challenge is not single good game but staying consistent in different formats and conditions. If he can do that he will be great asset for Pakistan cricket for years to come.
