Padres owner Peter Seidler has died at 63 years old, the team announced Tuesday.

“The Padres organization mourns the passing of our beloved Chairman and owner, Peter Seidler,” Padres CEO Erik Greupner said in a statement.

“Today, our love and prayers encircle Peter’s family as they grieve the loss of an extraordinary husband, father, son, brother, uncle, and friend. Peter was a kind and generous man who was devoted to his wife, children, and extended family.”

A cause of death was not immediately announced.

Seidler previously had two bouts with cancer, and underwent an unspecified medical procedure in September.

Seidler made his fortune in private equity.

He joined the Padres’ ownership group in 2012, and became the team’s largest stakeholder in 2020.

Seidler was the grandson of former Brooklyn and Los Angeles Dodgers owner Walter O’Malley and nephew of former Dodgers owner Peter O’Malley.

While the Padres did not have great success on the field in Seidler’s final years, it was not for lack of trying.

The team initially gave Manny Machado a 10-year deal worth $300 million in 2019, and then extended him last offseason on an 11-year deal worth $350 million to stave off an opt-out.

The Padres also acquired superstar Juan Soto from the Nationals in 2022, and gave Fernando Tatis Jr. a contract worth $340 million over 12 years last year.

The statement from Greupner, the Padres’ CEO, also paid homage to Seidler’s altruism.

“He also consistently exhibited heartfelt compassion for others, especially those less fortunate. His impact on the city of San Diego and the baseball world will be felt for generations,” Greupner continued.

“His generous spirit is now firmly embedded in the fabric of the Padres. Although he was our Chairman and owner, Peter was at his core a Padres fan. He will be dearly missed.”
