He is a young hamster and by the way he sounds he needs a patient taming process. How long have you had him for? I am guessing it has been 1 week (hams shouldn't be homed before 6 weeks). I wouldn't get him out of his cage at all for at least 1 week. Leave him completely alone (so no handling or touching), but still talk to him all the time, and maybe offer the odd treat every now and then. Gradually increase the amount of treat offering in the next week, and maybe place a treat on your palm and put your palm on the base of his cage. Let him come to you. Do this for a week. When he is comfortable with coming to your hand, then you can start lifting him up, but only do it in the cage for another week. Then the next week you can bring him out of the cage and spend some time going hand to hand. Never grab him, skittish hamsters don't tolerate being grabbed very well. If you feel like he's not getting too comfortable after a week, don't rush onto the next step, just prolong that step until he is comfortable. Only move to the next step once he is confident and comfortable in the activity. You can also use things like tubes or his ball to lift him out of the cage.
Balls aren't great, I believe they stress hamsters out and I have not used them due to this. Playpens are great, plus it enables you to interact with them also. I would only do this once he has built up some confidence with you (Like comfortable with being picked up at least).
Here is a tutorial I made on how to make a playpen, it's nice and large and fairly cheap.
