A base runner approaches home plate from the right side of the infield. When the ball is hit, he swiftly returns to third base, places his left foot on the home plate side of the base for a solid push off, spins his head to look for the catch, and sprints towards home plate on the catch. If no one has him, he enters the house with the ball. The base runner can also tag up if there is a chance he will be able to reach it before the batter reaches first base. In this case, he turns and runs towards second base while keeping an eye on first to see if the batter hits into a double play. If he does, then he continues running to third base. If the base runner doesn't get to any of the bases, he is out. If the ball is caught at any other position besides first base, the umpire calls "Tag!" and all the base runners continue toward home plate until only one base runner remains. He is entitled to a return trip if he wants it. The umpire signals that he is safe by calling "Out". This is very important because it gives the pitcher room to work in. If the batter hits into a double play, the catcher has time to retrieve the ball and throw to second base or first base if needed. This allows him to make better decisions about when to apply pressure to the ball and keep the batter from reaching base.
