Diving over another player

[Mattinglyfan]

Babe Ruth.. Runner rounds first base. Pitcher fields ball in foul territory, and throws behind the runner. The runner then Dives back to the bag over the first baseman. The umpire calls the runner out stating that it is illegal in Babe Ruth to dive over another player. Is this true ? Either way it was an amazing play. The player showed a tremendous amout of hustle.
