A front office executive recently called up video from Gunnar Henderson's high school days in Alabama and showed the reel to a colleague who did not see Henderson as an amateur.
"Oh my god," said the colleague, stunned by what he saw.
Henderson, likely to be named an All-Star for the first time tonight when starter selections are announced, is 23 years old and already considered to be one of the best in the majors. Just five years since Henderson was drafted by the Baltimore Orioles -- and little more than a year since he was promoted to the big leagues -- he is excelling at just about everything.
