Like Steve suggested..........always walk the field prior to calling the coaches for the plate meeting........
Tonight I called on a field that I have probably called 200+ games on........and I still gave the field a walk through............
AND.......you guessed it.......same situation.......sprinkler head exposed.......took me about 20 seconds to remedy the potential problem........
If I have not been on the field in awhile........I will usually even go as far as walking the fences and look for possible areas that the ball may enter DBT.......
Go ahead and call me anal.........but better safe than sorry..........
