Pakistan maintained 58% possession, while they also achieved a penalty corner in the first quarter which was well defended by Ireland’s Kyle Good.
Meanwhile, Pakistan vice-captain Shafqat Rasool missed an important chance in the second quarter.
Despite a high level of possession by Pakistan, Irish defenders and the goalkeeper handled it skillfully.
The match-winner by Alan Sothern in penalty corner action in the 46th minute kept alive Ireland’s dreams of making its first Olympic hockey appearance in a century.
This was the do-or-die chance for the three times Olympic gold medalist Pakistan team to qualify for the 2016 Olympic Games, which they lost to the Irish squad.
Pakistan lately could also not qualify for the field hockey World Cup.
