When Chicago catcher Tyler Flowers lost his grip on his bat, it went flying into the stands above left field.
Depesa, of Naperville, Ill., reached out with one hand and caught the bat before it hit the infant seated behind her. The man seated to her right merely ducked.
"I was more concerned with protecting the baby seated behind me," she told the MLB's Cut 4.
She reportedly got to keep the bat, which was later signed by Flowers himself.
