What I do is use a medium swing bowler, bowl the ball as close to the bowler as i can get it, swing it in at the stumps, and bowl it as slow as possible. The computer tries to hit the ball as if it were a bouncer and the ball goes under thier bat and hits the stumps. I can bowl any team out from 3 overs usually. this trick works really well if your not good at bowling, but tends to take the realism away from the game.
