Will Clark made one of the more memorable MLB debuts in San Francisco Giants history against the Houston Astros, just 26 days after his 22nd birthday.
When Clark stepped to the plate that day, he had a tall task ahead of him, beyond whatever inevitable nerves must come with that experience. Nolan Ryan, then a 39-year-old veteran entering his 20th season in the big leagues -- the Ryan Express himself -- stood on the mound staring Clark down.
You already know what happened. Clark took Ryan deep to center field for the round-tripper.
