When stretching, the 1B should land on the heel of his foot, as this will push you back to the bag making sure you don't pull your foot.
When fielding a bunt you should always use two hands. Anticipate getting the lead runner by setting up your feet to throw in that particular direction.
If you have to tag the runner, hold the ball with the throwing hand inside the glove. After tag, sweep arms in the direction of the runner and immediately separate hands with the ball still in throwing hand.
If you have to feed the pitcher covering first, move towards the pitcher, not the bag, and make sure you are showing him the ball. Underhand the ball whenever possible, and make sure it is a chest high throw. Use a stiff wrist when throwing underhand and only follow through to around eye level. Get the ball to the pitcher before he gets to the bag. If you have to throw overhand, throw the ball like you are throwing a dart.
