While I sympathize with her injuries, the problem is right in the first sentence: "...never saw...the bat...". If you are sitting in a ballpark - especially in the lower deck down the lines -and a batter is up you had better be paying attention to the game, not your phone, french fries or fiance.
There was an incident in another park caught on film last year where a father caught a bat just before it hit his son whose head was down looking at his phone. He was hailed as a (minor) hero. My first thought was :Nice catch Dad, but maybe you should teach your son safety too.
But Dowdell wasn't. Dazed and bleeding, she couldn't fathom what hit her head and face as she looked at the scoreboard during the game against the Cleveland Indians last July 23 at Oriole Park at Camden Yards. She heard herself moaning as if somehow detached from her body.
It wasn't until the Ellicott City woman arrived at the hospital — where court documents say her injuries included skull and orbital fractures and brain swelling — that she realized the 230-pound first-baseman inadvertently sent his bat windmilling into the seats at the end of a swinging strike."
