I knew the Minnesota Twins baseball team was young, but the proof was especially interesting.

Yesterday, Joe Christensen of the Strib noted that the Twins' starting lineup -- at an average age of 26.7 years old -- is the youngest in the American League and the second-youngest in baseball. Arizona's lineup is the youngest.

In the AL, the other teams with young lineups include the Oakland Athletics and the Tampa Bay Rays, which have average ages younger than 28.

The teams fielding the oldest lineups in the AL are the Toronto Blue Jays, the Detroit Tigers, and the New York Yankees, which have average ages older than 31.
