Agreeing with everyone else, he looks very safe in real time, in the replay, it looks a lot closer. If his foot is down, he's safe, but if it's up in the air a little bit, he's out.
He should have been safe by a mile. If you watch the replay, after he hits third, he's looking out at the outfield (over his left shoulder) and slows up while doing so. If he finds the 3B coach before hitting 3rd and picks him up after hitting the bag, he'd have seen him windmilling him home and Bernadina would have been safe by a step.
