West Indies is quite strong in T20 format, so it was not that surprising to see them taking a 2-0 lead against South Africa in the T20I series. Their main issue is that the players are simply not interested in representing the national side, as they can make far more money by playing various franchise T20 leagues. In both the matches, it was the South African bowling which failed, and ended up in gifting the matches to West Indies. They tried a few inexperienced bowlers such as Kwena Maphaka, Patrick Kruger and Lizaad Williams. But these bowlers failed to perform well.
you are right The West Indies team has always been very strong in the T20 format. West Indies players regularly perform in various franchise leagues. And almost every franchise performs well in the league. So this team is very strong in T20 format.
But the South African team is not weak. The South African squad includes some T20 specialist players like Stubbs, Hendrick Dussen and Marakram. However, the South African team lost both matches against the West Indies. I at least thought South Africa would make a comeback in the second match. But in the second match too, South Africa lost by 30 runs.
South Africa will face West Indies in the third and final match of the series tomorrow. We don't think South Africa will lose all three matches in the series. Hopefully we will see South Africa's comeback in the third match.
