Microphones for umpires?

R1 never got in a rundown between second and third. The throw from the outfield went to the fielder located right next to the first base bag. The fielder after catching the throw from the outfield on one hop, looked up and saw R1 trying to scramble back to second base. R1 fired to the middle infielder at second, and the tag was applied as R1 was diving head first back into second. R1 was then called out.

IMO, at the moment of the tag, U2 should have called "time".
