Legal force out

Question
(11-12 year old Dixie Youth league): Scenario: With two outs, the first baseman knocks down a ball bounced to him as a throw to retire the batter, stretches and retrieves the ball with his hand wrapped around the ball, but the ball still is touching the ground; can this be considered in possession of the ball or does it automatically count as a trapped ball? The two umpires disagreed with the call. The field umpire called it a trapped ball and the runner safe, letting the winning run score from third. After the game, the home plate umpire told me that he should have been out as he could see clearly that the first baseman had control of the ball.

Answer
If the call went against you the first thing that you should have done would be to appeal to the plate ump.

Even with the ball touching the ground a player can still have control. I once caught a ball in my armpit while playing first base and the out was given to me because I had control.

Having control is a judgement call for the umpires, but the ball touching the ground does not necessarily mean that there is no control.
