In fact, Afghanistan did not perform as expected in this match, Pakistan batsmen batted well and the bowling line was also excellent. However, Afghanistan batted badly from the 12th over to the 15th over and Afghanistan fell far behind here. Afghanistan collected only 6 runs in these 4 overs from 12-15 overs and lost 5 important wickets, due to which they were eventually all out. Rashid Khan tried well, but in the end could not lead the team to victory, Rashid Khan's performance is very commendable.
Now Afghanistan need to do both batting and bowling well in the next match, but Pakistan will be ahead in this series. I think Pakistan will win the series.
This match between Afghanistan and Pakistan was major turning point for series. You pointed out that Afghanistan loss came down to bad stretch from 12th to 15th over when they only scored six runs and lost five wickets.
You also noted that Pakistan strong batting and excellent bowling were key to their win. Only Rashid Khan played little well but it was not enough to lead Afghanistan to victory. Given Pakistan strong performance I also think that Pakistan will win this Tri Nation series.
