Catch or No Catch

[NuggDawg]

Outfileder on the run snags the fly ball, but before gearing down she collides with a teammate causing the ball the pop out of her glove and fall to the ground.

Is simply getting control of the ball in your glove enough for a catch or do you have to also have to show complete control of your body?

Speaking ASA

In the judgment of the umpire, the defender must have complete control and/or execute a voluntary release of the ball.

From ASA's 2009 Case Play Book:

A sinking line drive is caught by F7 who drops the ball after (a) tripping on the catch and hitting the ground, (b) colliding with F6 as they both reach for the ball, (c) starting to throw to the infield, or (d) running the ball into the infield and trips over 3B.
RULING: No catch in (a) or (b) if the umpire feels F7 did not have control of the ball. The fielder must show control and/or voluntary release of the ball prior to the ball coming lose because of contact with the ground or other fielder. In (c) and (d) since F7 has completed the requirements of a legal catch before dropping the ball or falling to the ground.
