This ball represents the last run given up and the last home run given up during the actual part of Bender's major league career. He did pitch one bullshit inning 8 years later as a coach but that shouldn't really count.
It is definitely the ball that caused the last loss.of his career. It is also the last run he gave up as a pitcher for a Philadelphia team.
The two run homerun by controversial Benny Kauff turned a 1-0 deficit in the 8th into a 2-1 victory. The victory clinched the 1917 pennant for the Giants, and this is the ball that propelled them to victory.
