Kevin O’Malley, a former part-owner of the San Diego Padres and a key figure in California minor league baseball, died Tuesday at the age of 50. He passed away from complications related to sepsis while under hospice care in Santa Barbara, according to his father, Peter O’Malley, the former president of the Los Angeles Dodgers.

O’Malley’s health began to decline last fall after he fell ill while in New York on business. He subsequently returned to Los Angeles for treatment, but his condition worsened over time.

A third-generation baseball executive, Kevin O’Malley was the grandson of Walter O’Malley, who owned the Dodgers from 1944 to 1979 and was inducted into the Baseball Hall of Fame for his role in bringing Major League Baseball to the West Coast. Kevin’s father, Peter O’Malley, served as Dodgers president from 1970 to 1998.

Kevin O’Malley spent the late 1990s working within the Dodgers organization, including stints in Great Falls, Montana, and Dodgertown in Vero Beach, Florida. He later co-founded Top of the Third Inc., a company that owned and operated minor league teams in Central California, including the Stockton Mudville Nine and the Visalia Rawhide.

In 2012, O’Malley joined the ownership group of the San Diego Padres, which included the Seidler and O’Malley families. The group sold the team in April of this year.

“Baseball was important to him,” Peter O’Malley said. “Family came first, but baseball was a close second.”

Born and raised in Los Angeles, Kevin O’Malley played baseball at Harvard-Westlake School before attending the University of Pennsylvania. He went on to earn an MBA from the Wharton School at Penn in 2004.

In 2010, O’Malley founded Carmelina Capital Partners, a growth equity firm where he served as managing partner.

He is survived by his wife Allison, their four children—Grace, Brendan, Brooke, and Margaret—his sister Katherine, brother Brian, as well as two nieces and two nephews. He was preceded in death by his mother, Annette.
