DRJ1960 wroteCollege Mechanics please. (Play occurred in HS game. Partner stated he was using NCAA mechanics on play).
3 man HS Regional game. R1 on first, one out. Deep line drive between F7 and
F8. U3 goes out for catch / no catch. What are base responsibilities for PU and U1?
(In case it's not obvious to all: PU has the plate, U1 is at first and U3 started play on the first base side of second base).
The set up is correct. 1BU is on the 1st base line. 3BU is on the 1st base side of the infield on a direct line from 2nd to 3rd base.
3BU is responsible for catch / no catch (provided he goes out in NCAA) between the left fielder and right fielder (the "V" as many call it). Once 3BU goes out, the umpire revert to a 2 umpire system. In this case, 1BU is responsible for R1's tag-up and for R1 into 2nd base. 1BU is also responsible for the BR to 3rd base.
Plate umpire is responsible for any play on R1 going into 3rd base.
