Petrus Jeftha, also known as "Oubaas" in his home town (Touws River), started his cricket career at a very young age. Everyone who grew up with him or was a part of his grooming as a child would tell you that his interest in cricket started even before he could walk. He was always involved whenever the game of cricket was played or even practiced. As a young boy he used to play, what is called, street cricket in his neighborhood. There already he was seen as one of the most talented cricketers among his peers.
Petrus started his schooling at the age of 6 when he attended the local primary school Steenvliet Primary School. It wasn't long before he joined the under 11 team to showcase his talent and love for the game. He was soon selected to play for the North Boland (A sub-district of the Boland) under 12 side where he was the youngest player in his team. At only aged 12 he was selected to play for the boland under 13 Schools team as a leg spinner and middle order batsman, where he soon gained great respect for those who watched him play as well as those who played with and against him.
Petrus was only 12 years old when he made his first century for North Boland against a highly respected South Boland. At the young age of only 13, Petrus joined his local cricket club, (Touws River C.C.), to improve on his skills as a cricketer. He soon became one of the club's most valuable players. During his time at the club he received various awards for his craftsmanship, such as man of the match and batsman of the year. When he was only 19 he scored a record breaking century of 180 off 134 balls, making this the fastest century in the history of Touws River Cricket Club.
After completing his primary education Petrus received a bursary to go to the respected Worcester Gymnasium where he spend his high school career. It is here where his talent was truly developed as not only a cricketer but also a rugby player. Petrus continued representing boland at school level in cricket. In 2005 he represented boland at the Coca-Cola under-18 Craven Week annual rugby tournament. Later that same year he was selected to play for the South African under 18 side. He also represented Boland at under 21 level after finishing his secondary education. His cricket career did not suffer because when it was of season for rugby Petrus still played cricket.
