Former major leaguer Jimmy Piersall, who bared his soul about his struggles with mental illness in his book “Fear Strikes Out,” has died. He was 87. Piersall died Saturday at a care facility in Wheaton, Illinois, after a monthslong illness, according to the Boston Red Sox, for whom Piersall played for seven of his 17 seasons in the majors. He played 56 games in the majors before being admitted to a mental hospital with what was later diagnosed as bipolar disorder. He returned to the majors in 1953 “sound and healthy” thanks to “shock treatments, faith, a wonderful wife, a fine doctor and loyal friends.” He went public in an attempt to shatter society’s stereotypes of the mentally ill.
