From Murray Chass:

Rizzuto was then a Yankees broadcaster, but he was also a bunting instructor in spring training. One day, he stood at the net as players bunted in the batting cage under the stands along the right-field line at Fort Lauderdale Stadium. Scooter knew better, but he absent-mindedly held on to the net behind home plate, putting his hand through an opening between the cords.

A foul ball came off the bat and smashed Rizzuto’s finger. ...

When we arrived at the hospital, the nurse at the outpatient desk asked Rizzuto for the usual information. Date of birth was one of her questions.

“Sept. 25, 1916,” Rizzuto replied without hesitation. With “16” hardly out of his mouth, he turned to me and said sternly, “Don’t you tell anybody.”
