1) BR bits a foul pop up towards left field line, 3B reaches over fence to make the catch then the momentum carries her over the fence and she lands into DBT while retaining the ball in her glove. Good catch (out) or not?

2) BR hits a deep fly to LF and at the warning track the LF reaches for the catch and the fence gives way, LF makes the catch but falls over the fence as it bends into HR land? Good catch (out) or not

In both cases its a "catch & carry" ... its a catch & unintentional carry into DBT. I believe the award is one base from the when ball went into DBT - intentional carry into DBT would be a 2 base award (I believe).
