He was 80.
"My personal condolences to the Buck family and the Phillies family," Phillies general manager Ruben Amaro Jr. said. "It's a tough loss for a very special family. He will be missed."
The Phillies have a limited partnership with David Montgomery, the general partner. The four limited partners include: Claire S. Betz; Tri-Play Associates, which included Buck and his brothers J. Mahlon Buck Jr. and William C. Buck; Double Play Inc., with John S. Middleton its chairman; and Giles Limited Partnership, which is Bill Giles' family partnership.
"Over the last 29 years, I cannot tell you how supportive they have been of me personally, Dave Montgomery and the entire organization," Amaro said of the ownership group. "They've given us the ability to do a lot of special things here in this organization. It's just our hope that we provided some special memories for he and his family."
