1931 USA Outdoor Track and Field Championships

The men's edition was held at Memorial Stadium in Lincoln, Nebraska, and it took place 3–4 July.

At the men's championships, Percy Beard set the 110 m hurdles world record.

As the event fell out of favor after 1957, the mark is presumed by Track & Field News to be the world record for the farthest baseball throw by a woman as of 2021[update].

One of her return throws struck James McBride, a spectator, and Walsh was subsequently arrested.

Walsh was eventually set free, though she soon after moved to Poland and did not compete again at the USA Outdoor Championships until 1939.
