An awful sound, something like a broken plastic bat hitting a Whiffle ball, echoed throughout RFK Stadium when Rajai Davis made contact against starter Tim Redding in the second inning.I am all for capitalizing proper nouns, but Whiffle ball, as the story has it, is not the name of the perforated plastic ball. The trademarked name is Wiffle ball.
The generic name for it is whiffle ball, so it may be lowercased.
So what could you call an error like that? A whiff?
