Neighborhood plays

[mpeterson_1]

I am posting in regard to two different plays that generally get lumped together in discussion. The first is at 2nd base during an attempted double play. F4 straddles the bag, recieves the throw from F6 clearly before R1 gets there, relays the throw on to first, but never actually touches the bag. I am likely to call R1 out as long as F4 makes a throw on to first base. If, however, no throw is made, contact with the bag is necessary.
The second instance is on a play at first base in which the throw clearly beats the B/R and F3 pulls his foot off the base early to avoid injury. I'm also likely to call the B/R out as long as the play clearly beat him. However, if the play was close, F3 must keep contact with the bag.
These are both examples of ad/disad., no? I'd like to hear some thoughts on this.
