Geff,
It is catcher's interference..but only if the coach wants it...unless the scorekeeper ruled it a base hit then the play stands as if there were no interference. In this case If I were the manager and it was NOT a base hit, I would take the interference, my batter goes to first and all runners are forced to advance, scoring the run from third. You can read the rules:
The batter becomes a runner and is entitled to first base without liability to be put out (provided he advances to and touches first base) when the catcher or any fielder interferes with him. If a play follows the interference, the manager of the offense may advise the plate umpire that he elects to decline the interference penalty and accept the play. Such election shall be made immediately at the end of the play. However, if the batter reaches first base on a hit, an error, a base on balls, a hit batsman, or otherwise, and all other runners advance at least one base, the play proceeds without reference to the interference. If catcher's interference is called with a play in progress the umpire will allow the play to continue because the manager may elect to take the play. If the batter runner missed first base, or a runner misses his next base, he shall be considered as having reached the base, as stated in Note of Rule 7.04 (d). Examples of plays the manager might elect to take: 1. Runner on third, one out, batter hits fly ball to the outfield on which the runner scores but catcher's interference was called. The offensive manager may elect to take the run and have batter called out or have runner remain at third and batter awarded first base. 2. Runner on second base. Catcher interferes with batter as he bunts ball fairly sending runner to third base. The manager may rather have runner on third base with an out on the play than have runners on second and first. In situations where the manager wants the "interference" penalty to apply, the following interpretation shall be made of 6.08 (c): If the catcher (or any fielder) interferes with the batter, the batter is awarded first base. If, on such interference a runner is trying to score by a steal or squeeze from third base, the ball is dead and the runner on third scores and batter is awarded first base. If the catcher interferes with the batter with no runners trying to score from third on a squeeze or steal, then the ball is dead, batter is awarded first base and runners who are forced to advance, do advance. Runners not attempting to steal or not forced to advance remain on the base they occupied at the time of the interference. If the catcher interferes with the batter before the pitcher delivers the ball, it shall not be considered interference on the batter under Rule 6.08 (c). In such cases, the umpire shall call "Time" and the pitcher and batter start over from "scratch."
