Former NFL Super Bowl-winning offensive lineman and current ESPN analyst Mark Schlereth must be very proud of son Daniel. When the younger Schlereth took the mound for the Arizona Diamondbacks in a scoreless 6th-inning relief appearance May 29, Schlereth-squared made father-son history as only the 6th duo to have an NFL and MLB player in the family.

The other five? There's an ex-Cub in there ...

Yogi Berra (MLB) - Tim Berra (NFL)

Lou Brock (MLB) - Lou Brock (NFL)

Jack Snow (NFL) - J.T. Snow (MLB)

Lee Gross (NFL) - Gabe Gross (MLB)

Don Patterson (NFL) - Corey Patterson (MLB)

Schlereth the elder has a history of being a huge backer of his son, going so far as to produce a documentary on Daniel's season as the University of Arizona closer in 2008. And he was all a-Twitter for the kid's Big League debut against Atlanta.

Daniel Schlereth was a first-round pick in the 2008 draft.
