On August 16, 1920, while at bat, Chapman was struck in the head and killed by a pitch thrown by
Carl Mays during a game against the
New York Yankees at the
Polo Grounds. At the time, pitchers commonly dirtied balls with soil,
licorice, and
tobacco juice, and otherwise scuffed, sandpapered, scarred, cut, or spiked them, giving a "misshapen, earth-colored ball that traveled through the air erratically, tended to soften in the later innings, and as it came over the plate, was very hard to see." Mays threw with a
submarine delivery, and it was late afternoon. Eyewitnesses recounted that Chapman did not react to the pitch at all, presumably unable to see it. The sound of the ball striking Chapman's skull was so loud that Mays thought it had hit the end of Chapman's bat; he fielded the ball and threw to first base. Chapman was taken to St. Lawrence Hospital, a short distance from the Polo Grounds, where he was diagnosed with a depressed
skull fracture. Despite emergency surgery to relieve swelling on his brain, Chapman died at 4:40 am the next day. His pregnant wife Katie, summoned from
Cleveland by phone, arrived at 10:00 am and fainted upon learning he had died. Thousands of mourners attended Chapman's funeral at the
Cathedral of St. John the Evangelist in Cleveland, Cleveland players wore
black armbands for the remainder of the season. The Indians won the
1920 World Series and dedicated their victory to Chapman. ==Honors==
