I may not be remember this totally correctly, and if so I'd certainly like to get it straightened out Bob.
In regard to the rule you cited, 7.05h AR:
Notice how it says the ball "remains on the playing field". This could just as easily say "and comes to rest", because I believe that is what it is interpreted as.
If a pitch is trickling to the dugout, and the catcher leans over, stumbles, and muffs it into the dugout, its one TOP because the ball did not come to rest. If he does so intentionally, he is considered to have changed the status of the ball to a thrown ball, and two is given from the time of that deflection. Same thing goes on a ball that richocet's off the baskstop, back into the catcher, and then into DBT, 2 bases, time of deflection.
I really am almost sure of this Bob, because I think 7.05h AR (the second paragraph that is) only applies when the ball comes to rest.
If someone has J/R or JEA on this hidden away somewhere, either way, now's the time!
Don't care if I'm wrong, would just like to know it.
