Triegaardt, who has been Northern Cape’s Head Coach since the summer of 2014/15, has been appointed to lead the amateur side on a two-year deal.
The Kimberley native served as assistant coach for the National Academy for a two-year period from 2014, and fulfilled a similar role for South Africa ‘A’ in 2015.
In his final year as coach of the Northern Cape Provincial Team, he guided his side to the Africa T20 Cup final.
As a wicketkeeper batsman Triegaardt spent four years at Griqualand West from 2009 before finishing his first-class career with a season at the VKB Knights in 2012/13.
The 33-year-old will take charge of Northerns Seniors from 12 July.
“I’m very excited and can’t wait to be part of such a successful Union,” said Triegaardt.
“I am looking forward to the opportunity of working with the younger players and influencing their development into franchise players.”
Cricket Operations Manager Johan Muller said: “We are pleased to have JP with us. His team’s performance in the Africa T20 Cup last year is evidence of his success at this level.”
“JP will be in charge of a fairly mature team, with a good blend between experience and young talent. With his committed and hardworking nature he will fit into our culture with ease. JP will have a strong support base to rely on.”
“Following changes to the coaching staff when we appointed Mark Charlton as Titans High Performance Manager, we believe JP is the best candidate to take the side forward.”
