And that's not the only practice in which they differ with the owners of the OBR.

Where have the owners ever commented on this?

"The running lane does not come into play unless the throw is coming from behindthe batter-runner (so a throw from the 3rd baseman will not involve the running lane)"

This point is not present in the OBR!So,the running lane in the OBR,is it good for all the infielder's plays?

Yes. The general thought is that a throw from outside the box where the plate and the pitcher's mound are opposite corners that hits the runner cannot be a "quality throw".

Not that interference isn't possible; just that it's extremely unlikely.

Grazie BOB!!! I understand, but an ultimate question: what do u mean for "quality throw"?

Catchable with ordinary effort by the fielder taking the throw at first base. If the fielder has to leap, go after, dive, or whatever it isn't a quality throw. If he can't catch it at all it's not a quality throw.

With experience, you'll get a better feel for the game and it will become more and more obvious.

Good luck.

But what if the "quality throw" is not quality because of the BR running outside the lines.... Bunt, catcher comes out and feilds ball, BR is running outside the lines towards the pitchers mound, catcher comes up throwing and throws HIGH..... If if the opinion of the PU his throw was errant becasue of BR he's out for interference.

OBR: no INT, play on
FED: INT

This is exactly the reason why FED wants INT here, regardless of the quality of throw. Catchers playing under OBR need to know to throw it to F3 even if it hits the BR.

Agreed.

But (for completeness), if BR was running on the foul side of the lane (the ball is fair in this play), and F2 makes an errant throw, BR is not out even in FED.

Too often I read, "If BR is out of the lane, he's out, evne on a non-quality throw" and that statement is just a little too broad.

Right. The FED rule says the infraction is ignored if the B/R does not interfere with either the fielder or the throw. The rule needs no interpretation. Nevertheless, FED mucked it up when they tried to clarify that a runner need not be hit with the throw for INT to occur. It came out, as Bob said - if the B/R is out of the lane and if there is a throw, INT is presumed (no quality throw required). That's more than an interpretation - it's a rule change.

I think Tim C was at the board/committee meeting and reported the interp. on this forum. It might have emanated from Elliot Hopkins.

It was an interp (throw over the head of F3), like in 2005. I don't recall seeing it in rule or in case book. If you can point me to it I will stand corrected, and thank you for the education.

but the OBR clarify that is interference only if the batter-runner INT with the taking of first baseman, not with the shot of the catcher....ex: the assistance of Catcher hit the body of batter-runner outside the line....is INT because that INT with the taking of first baseman.....is right???

That's how the rule reads, yes.

We have a coach here that teaches his players to run inside the running lane on ground balls to the infield. Now, a throw from the F5 (charging in), which F3 has to reach for (up the foul line), causes either a hit runner or a minor collision (with F3's mitt), just before B1 reaches the base. (B1 is/was clearly out of the running lane leading up to the base.
Would we have anything in iether fed, obr or mlb?

I fixed it for you.. read the rules, it does not say anything about a quality throw..LOL dont read into the rule so much.

Rule 6.05k
In running the last half of the distance from home base to first base, while the ball is
being fielded to first base, he runs outside (to the right of) the three-foot line, or
inside (to the left of) the foul line, and in the umpire’s judgment in so doing
interferes with the fielder taking the throw at first base, in which case the ball is
dead; except that he may run outside (to the right of) the three-foot line or inside (to
the left of) the foul line to avoid a fielder attempting to field a batted ball;
