If you have spotted a pokemon in the safari zone that you want, got to where you found it, then DONT MOVE just TAp the d-pad in a direction, you will turn, but not move, pokemon still apear, but you dont lose time, now when you find your pokemon, throw some bait, this will make it unlikely to run, then thow a rock, it is much less likely to run using this method than if you just throw rocks, then throw a pokeball, this will work most of the time.
