The reason being that they do not have that form they require. This tournament will surely give the players a little more international experience and they will be more confident in the future ODI's. In the tournament, Kenya have a few new players like Ravindu Shah. Ravindu is a good all rounder and that is the best thing to have in the team. South Africa have been successful in both one day and test due to the all rounding from most of their players.
Motivation has a very important role in cricket.
West Indies in the '96 World Cup is a clear example. Although West Indies has an excellent squad, they were unable to make 167 to win the match. The Kenyan seam bowlers had the motivation and picked up all the wickets before West Indies could reach 100. Although Kenya have a lack of fast bowlers, they have quite a few medium bowlers who can move the ball. Martin Suji is the quickest bowler in the Kenyan side at the moment.
