A serious head injury caused by a freak baseball accident changed Jeremy Giambi's demeanor in the six months leading up to his death, a new medical examiner's report reveals.
According to the documents, obtained by TMZ Sports on Thursday, the ex-MLB player was struck in the head by a baseball while working as a pitching coach in August 2021.
The accident caused a serious injury -- investigators say he suffered a fractured zygomatic bone, and required surgery to fix the issue.
But, according to the report, witnesses told them that in his recovery from the injury, Giambi became "very emotional, very negative and would let the smallest things ruin his day.
