More details are coming out about what unfolded in the months before Jeremy Giambi died by suicide.

The former Oakland Athletics player died in early February at age 47. His cause of death was confirmed as a suicide two days later.

A report from the L.A. County coroner, obtained by PEOPLE Thursday, reveals that Giambi was hit with a baseball in Aug. 2021, breaking his cheekbone.

Giambi "had not been the same since," the incident, his mother, who found him unresponsive after his death, told authorities per the coroner's report. She said the athlete was "very negative, emotional, and paranoid" following the injury.

She shared that although the Giambi, who was working as a pitching coach at the time, had surgery to treat the injury, he "seemed different." He also went to a neurologist but was never officially diagnosed with any condition. She said after the injury, Giambi was "very negative and would let the smallest things ruin his day."

Following Giambi's death, a number of MLB teams as well as current and former stars shared their condolences to the Giambi family.

Alex Rodriguez, who played on the New York Yankees with Giambi's older brother Jason, wrote on Twitter, "Heartbroken to hear the news about Jeremy Giambi's passing. He was the ultimate competitor on the diamond. Just 47, gone way too soon. My thoughts are with his family and friends. RIP."
