It's Opening Night for baseball, and most teams have their Opening Day Monday. I looked at the Orioles' roster and the oldest player is catcher Gregg Zaun, born in April 1971.
I met him as a 19-year-old playing in Bluefield, the Orioles' Appalachian League team. The Los Angeles Times called the team's office to find out how he was doing, and as the team beat writer I informed them of his progress. Now he has a World Series ring (Marlins in '97) and comes to Baltimore as the veteran teacher to hopefully a phenom - Matt Weiters.
