Shepherd slammed 44 no longer out off 22 balls to boost the West Indies from 161 for 8 to 220 for 8, sharing an unbeaten 9th wicket stand of 59 off 26 balls with Joseph, who made 14 no longer out.
Fast bowler Joseph then took 5 for 40 as South Africa had been limited to 213 for 6.
New West Indies T20 captain Rovman Powell stated the gamers had spoke back to his name “to be fearless, to be natural – but you have to be smart too. The guys were excellent in this series.”
Joseph, who neglected the second one tournament in Centurion when South Africa completed an international file run chase of 259, struck the most important blows when he took the wickets of T20 stars Quinton de Kock (21) and David Miller (11).
Joseph successfully wrapped up the tournament within the penultimate over when he pushed aside top-scorer Reeza Hendricks for 83 and adopted up with the wickets of Heinrich Klaasen and Wayne Parnell.
“We made a total and it was up to the bowlers to defend it,” stated Joseph, who used to be named participant of the tournament.
“I thrive on the opportunity to make an impact.”
The closing two overs of the West Indian innings had been match-changing as Shepherd and Joseph scored 17 off Wayne Parnell and 26 within the ultimate over bowled by means of Kagiso Rabada.
“We would have liked to wrap up the last two wickets but bar the last two or three overs we were really good with the ball,” stated South Africa captain Aiden Markram.
