In May 1903, in an away game against the New York Giants, Doheny popped up and then threw his bat in the direction of Giants
catcher Frank Bowerman, angering the crowd. For this, Doheny was suspended for three days. In July, Doheny left the Pirates and returned to his home in
Andover, Massachusetts. He had been acting strangely and was convinced that he was being followed by detectives. As the
Pittsburg Post noted on July 29, "his mind is thought to be deranged". Doheny returned to the team in August. He pitched well and ended the season with a record of 16–8 and a 3.19 ERA, helping the Pirates win the NL championship. He played his last game on September 7. Doheny continued to suffer from paranoid delusions, and on September 22, his brother took him back home to Andover. Doheny was then placed under the care of Dr. E. C. Conroy and a nurse, Oberlin Howarth. Doheny's condition did not improve and was worsened after he read about the Pirates' fourth loss in the
1903 World Series. On the night of October 10, he forcibly removed Conroy from his home. Early the next morning, Doheny attacked Howarth with a cast-iron stove leg and knocked him unconscious. The police arrived, and Doheny held them off while threatening to kill anyone who approached. After an hour, the police finally overpowered him. Doheny was declared insane by doctors and committed to an asylum in
Danvers, Massachusetts. Doheny finished his nine-year MLB career with a 75–83 record, a 3.73 ERA, and 572
strikeouts. He never recovered from his mental illness and died in an asylum in
Medfield, Massachusetts, in 1916. ==See also==
