Via the Advocate:
Hamilton usually pitches wearing what appears to be glasses, but they are not really functional because the lenses have been removed. It's a ritual she started in high school.
"Every athlete has a superstition, something that gives them a good feeling," Lotief said. "For (Hamilton), it's the glasses. There was a time when she took them off. I told her to put them on. She's more confident when she has them on."
The specs work for Hamilton, just like the beard works for this Minnesota hurler.
