Do not try hitting the ball for six when its right into your foot (Yorker). Instead, play aggressive shot for sweep. It works quite often.
Try building your confidence meter before attempting any big shots.
When the CPU assigns defensive field, defend the deliveries in the offside more often to clinch a single run. Remember try to clinch the single quickly or you will be run out.
You will find medium fast bowlers tougher to handle than the faster ones. Do not hit slog shots. You will succeed one or two times then will definitely get out.
For Slogging, hit the ball just before it lands on the ground and you will find that it will reach the fence.
