Stickball is a Native American (Choctaw) sport similar to Baseball.
The Choctaws gave Ireland a consignmentt of grain during the famine as they could identify with the starvation. Taoiseach Leo Varadkar paid the first ever visit by a sitting Taoiseach to the Choctaw Nation on St. Patrick’s Day 2018, and played a bit of Stickball.
