Injury "Timeout"

[chapmaja]

Here is the situation.

Team A is at bat. B4 hits a single, routine play, nothing special. At the end of the playing action I see the B4, now standing at first, requesting time. I grant time and she immediately goes down to the ground. Turns out she has a calf cramp. I give her time to stretch out the cramped leg and be able to return. During the quick break (no more than 2 minutes), the DC comes out complaining she is wasting time and they have 3 subs, she has to use them .

What is the proper rule on this. My response was that it was my judgement on the amount of time needed. Was this correct?

The DC was a pain all game, questioning almost every call during the game.
