What size bat Jackie Robinson used?

Answer 1

He swung a 36-inch, 40-ounce Louisville Slugger with a thick, untapered hitting end and a much thicker than average handle - - - a modern-day variant of the Heinie Groh "bottle bat." If you pick one up it feels like a telephone pole, but remember: Robinson was incredibly strong and had huge hands.

Answer 2

Hank Aaron's preferred bat size and model was a 35 inch 33 ounce, Blond Hillerich & Bradsby A99. This is the bat he used to hit home run number 704. He also used models A93, A96, A99, A112, A115, D89, R43, S2, T73 and Adirondack 63 A. Most of Aaron's game used bats fall into the 35 inch length, 33 or 34 ounce range throughout his career, although a few orders of 34 inch and 35 1/2 and 36 inch models are documented.
