Ah, found it. The "high intensity data retrieval system" hard at work.

This is actually from April 2010 Plays and Clarifications...

Play: B2 slaps the pitch toward the right side of the infield and F3 fields the ball with their bare hand and dives for 1B. In the base umpire’s opinion, F3 has control of the ball and is holding the ball securely while diving on 1B and touching it with the ball. As soon as F3 touches 1B with the ball, the ball rolls loose into foul ground.

Ruling: This is a judgment call by the umpire in regards to F3 having control of the ball when touching 1B. The runner should be ruled out if the umpire judged the fielder had possession of the ball at the time of touching the base, regardless of the ball coming loose after touching the base. The issue is control for that split second that the ball touches the base. If control is established when the fielder touches the base B2 would be out.
