BALTIMORE (WJZ) —  He never went to college, but Hall of Fame Iron Man Cal Ripken Jr. knows a lot about life, hard work and success.

He will share what he’s learned with 7,000 University of Maryland College Park undergraduates this spring. Ripken has been chosen to be the commencement speaker for the Class of 2013. 

He says as a lifelong Marylander, he’s excited to deliver the speech.
