who gets hit by a batted ball. It doesn't matter if he intended to interfere with the ball or even if the runner clearly is trying to avoid contact with the ball. As long as the ball makes contact with the runner before a defensive player touches the ball, the runner is out.

In this case, the runner coming home from 3rd is not permitted to move out of a direct path between where he's running and home to initiate contact with a catcher. As soon as the runner (a) deviates from a straight path to home, and (b) in the process makes contact with the catcher, he's violated the rule. Given the level of injury to Lucroy, a two game suspension is extremely reasonable.
