Hi Richard,
The game has changed over the years, and easy steals on H&R’s aren’t that easy anymore.
My old SAC/H&R booklet (purchased in 1974) had the following results on H&R plays:
13 – Strike – runner out stealing; A-C PO-SS; IF RUNNER HAS AN ELEVEN IN THE FIRST COLUMN OF HIS PLAYER CARD, HE STEALS SAFELY
14 – Ball – runner out stealing; A-C PO-SS; IF RUNNER HAS A TEN OR ELEVEN IN THE FIRST COLUMN OF HIS PLAYER CARD, HE STEALS SAFELY
However, my newer booklet (printed in 2013) has the following results on H&R’s:
13 – Strike – runner out stealing; A-C PO-SS
14 – Strike – runner out stealing; A-C PO-SS; IF RUNNER HAS AN ‘11’ IN THE FIRST COLUMN ON HIS CARD, HE STEALS SAFELY
So, in answer to your question… yes, the rules have changed. It was probably way too easy to get a (F) runner with an Eleven on his card to second base, especially with a strikeout-prone hitter at the plate. And APBAGO reflects those newer boards.
