Basic question.........(stupid)

[flamin-gitaur]

Hey guys, I have a question, hope you can help.

If there is a runner going to 1b, and the ball gets thrown to the first baseman but drops it, has to reach for it, so his foot comes off the bag, then scoots the ball to him while trying to get his foot back on the bag, would the runner still be out if the ball never came off the ground? In other words, if the first baseman simply made contact with the ball with his glove while it was on the ground and the bag, is the runner still out, or does he have to have full posession of the ball, and by full posession I mean off the ground "in" his glove or hand?

Thanks
