re: Two feet to the left of the baseline is interference

p. In running the last half of the distance from home plate to first base while the ball is being fielded to first base, the batter-runner runs outside the 3-foot restraining line or inside the foul line and, in so doing, interferes with the fielder taking the throw at first base, except that the batter may go outside these lines to avoid a fielder attempting to field a batted ball;

Note 1: If the batter-runner is running illegally to first base and his being outside the lane alters the throw of a fielder, hinders or alters a fielder’s opportunity to field the throw, or the batter-runner is hit by the throw that has been made in an attempt to make a play, it shall be called interference and the batter-runner is to be called out.

Exception—The batter-runner is permitted to exit the three-foot running lane by means of a step, stride, reach or slide in the immediate vicinity of first base and for the sole purpose of touching first or attempting to avoid a tag. He may exit the running lane on his last stride or step if he has been running legally within the running lane up to that point.

Note 2: The batter-runner is considered outside this 3-foot lane if either foot is outside either line.
