2.25 COMMENT:

COMMENT: Determining when a ball becomes dead on a foul is sometimes tricky. With R1 on second and no one out, consider the following: (1) An attempted bunt on a third strike by B2 is a foul fly that is caught by F2. B2 would have been out without the catch, but because of the catch, the pitcher is not credited with a strikeout and R1 may attempt to advance after the catch. (2) The first strike on B2 is a foul fly that comes down near the wall with F2 attempting a catch. A spectator reaches into the field of play and deflects it and (a) prevents the catch, or (b) F2 makes the catch. In (a) and (b), the ball shall be dead at the moment of spectator interference. B2 is declared out and R1 will be awarded the bases the runner would have reached in the judgment of the umpire had there been no spectator interference (8-2-12). (3) B2 hits a high foul fly to right field which is not caught. R1, who was on second, has passed third before the ball becomes dead. The runner must return to second. (4) A pitch touches the bat of B2. In (a), it goes directly to the catcher's glove then caroms against her protector and rebounds into her hand or glove; or (b) it goes directly to catcher's protector or mask and rebounds into her hand or glove. In (a), it is a foul tip and a catch. The ball remains live. In (b), the ball becomes dead when it touches the body of F2. (5) A pitch touches the bat of B2 and loops over the catcher's head (never higher than the batter's head). F2 lunges backward and makes a diving catch. B2 is out and the ball remains live.


The ASA case book has this same ruling. But the PDF I have is copy-protected, so I can't cut and paste...and I'm not typing out all of that! The case play in my several years old case book is 1-59.
