Baseball player Billy Martin inducted into Army

Billy Martin, a star from the last World Series, is leaving the Yankees to join the Army for two years. At 25, he is inducted in San Francisco, marking his second Army service after a brief stint in 1950. This transition involves a salary cut, but it is a gain for the Army as Martin bids farewell to baseball temporarily.
