LL's often have lightning detectors that go off if lightning is within X number of miles. Any park that utilizes metal bats on a regular basis should have them. That would include college parks. I realize Rosenblatt is a pro stadium but this is a huge college event. At worst, play should be stopped on the first sign of lightning. Most youth baseball governing bodies use twenty minute delays from last spotting of lightning.
It's never been proved statistically metal bats are a safety issue for pitchers. But everyone knows metal elevated off the ground attracts lightning. I wasn't watching last night. Was there lightning and wet ground? If the lightning hits wet ground it can affect every player on the field.
Didn't the recent football events convince you major D1 sports are all about money and the term student-athlete is a joke?
