Former Ireland captain William Porterfield announced his retirement from international cricket on Thursday, calling time on a 16-year career during which the team has progressed from an amateur side to a Test-playing nation.

The 37-year-old left-handed batter led Ireland in a remarkable 253 games across all formats, a span that included two 50-over World Cups and five T20 World Cups as well as the Irish men's inaugural Test, against Pakistan in May 2018.

"It's been an honour to represent my country for 16 years," said Porterfield. "It's something I had always wanted to do since I was a child.

Porterfield, who will take up a coaching role with Gloucestershire, played his last international in January at Jamaica's Sabina Park.
