Ncube first played cricket on the streets of Bulawayo's Gwabalanda township, going on to represent Milton High School before finding a place in the Western Under-19s and B teams, where impressive performances helped him find a place in the Zimbabwe Under-19 Cricket Team. He had represented Zimbabwe at the 2008 ICC Under-19 Cricket World Cup in Malaysia, where he took 1 wicket for 12 runs in 7 overs in the match against New Zealand Under-19s. He plays for Amakhosi Cricket Club in the club league in Zimbabwe.
Domestic career
Westerns career
He spent a couple of seasons with the Matabeleland-based Westerns until the revamping of Zimbabwe's cricket structure in 2009. He made his First-class debut, List A debut and Twenty20 debut for them.
Move to Mountaineers
After the Zimbabwe's domestic structure was reconstructed, Ncube moved to Mountaineers in 2009, but the move was not successful, and returned to Matabeleland Tuskers in 2010. He currently plays domestic cricket for them.
International career
ODI debut
He was selected for the New Zealand cricket team in Zimbabwe in 2011–12 ODI series. After this, he made his ODI debut in the 3rd ODI where he took 3 wickets in his debut match. He became one of only eight Zimbabwean bowlers to take three or more wickets on debut. Zimbabwe won by 1 wicket in the penultimate ball of the innings as they recorded their highest ever successful run-chase.
He made his Test cricket debut against New Zealand at Bulawayo on 1 November 2011. He took his maiden Test wicket with the dismissal of Ross Taylor, caught by the wicketkeeperRegis Chakabva. While it was his first dismissal in this format, it was also Chakabva's first dismissal in Test cricket. It was Ncube who bowled economical overs, maintained disciplined line and lengths, and took most of the advantages of the conditions early on. In July 2016 he was named in Zimbabwe's Test squad for their series against New Zealand.
Bowling speed
Ncube normally bowls at a speed of 128–135 kmph. On his day he can bowl quick and naturally hit the deck bowling inswing cutters but has been working hard on his outswingers. However, now he bowls fine outswingers in tandem to his inswingers as he showed in this debut ODI and Test matches for Zimbabwe.
