If the ball bobbled, bounced or whatever in the pocket, which is what I saw, the player did not have control of the throw and the catch was not made until the ball was caught after the bobbled and the ball was securely in the glove. A bobble or bounce in the gooce is no control. Basic rule Definition of a catch.
Then the questions are: did the pitcher have control of the ball (after the bobble) and his foot on the base at the same time? Did the pitcher have control and his foot on the base before the runner touched the base? I need a frame by frame on this.
you are correct BUT the bobble was controlled before the runners foot tapped the bag.
I think the general rule would be that when the ball is finally secure, the catch is made. This is ultimately irrelevant, though, as like I said the ball was secure long before Donald reached the bag.
