Oklahoma USA Umpires

Any words of encouragement or improvement for this umpire?

Play: B3 is in the batter’s box. R1 is on 3rd base and R2 is on 1st base. B4 swings at the pitch and tips F2’s glove and hits a slow roller to the F1. R1 stays at 3B, R2 makes it to 2B base and B3 is out at 1B. As B4 walks up to bat the head coach for the offensive team asks for time. The coach asks the plate umpire about the catcher obstruction. What is the ruling?

Play: (Coed SP) No outs in the 3rd inning B1 (a female) hits a double to left field. The team manager sends a male roster member in as a courtesy runner for B1. The umpire does not allow the courtesy runner because male runners cannot be used as courtesy runners for female players and female runners cannot be used as courtesy runners for male players. Was this the correct ruling?

Plays and Clarifications: Play: R1 on 2B, R2 on 1B, 2 outs and B5 at Bat with no count. F1 delivers an illegal pitch. B5 hits a ground ball to F6. As F-6 is attempting to make a play on the batted ball, R1 lowers their shoulder and plows into F-6, driving them to the ground. The umpires call time and interference and call R1 out and since this is the third out end the inning. Is this the correct call?
