catcher stepping and meeting the ball

[fastballbaker]

What is the ruling???

Runner at 3rd base. He tries to straight steal home.
As the pitch is on the way to the plate the catcher jumps
and meets the ball IN FRONT OF THE PLATE. He catches the
ball and tags the runner out trying to steal home.
Factors: The batter did not attempt to hit or bunt the ball. The catcher did not hit the batter while going to
meet the ball. The catcher did not even let the ball cross the plate. Is the pitch a ball or a strike??? What is the
ruling... Thanks
