Henry Zimmerman (February 9, 1887 – March 14, 1969), known as "Heinie" or "the Great Zim", was an American professional baseball third baseman.

In the fourth inning, the game was scoreless when Eddie Collins of the Chicago White Sox was caught between third base and home plate.

Catcher Bill Rariden ran up the line to start a rundown, expecting pitcher Rube Benton or first baseman Walter Holke to cover the plate.

With no one covering the plate, third baseman Zimmerman was forced to chase Collins, pawing helplessly in the air with the ball in a futile attempt to tag him.

A quote often attributed to Zimmerman, but actually invented by writer Ring Lardner years later, was that when asked about the incident Zim replied, "Who the hell was I supposed to throw to?

Based on testimony by McGraw during the Black Sox Scandal hearings in the early 1920s, Zimmerman and Chase were both indicted for bribery.

Zimmerman denied McGraw's accusations, and neither he nor Chase was ever proven to be directly connected to the Black Sox.
