PHILADELPHIA -- Alexander K. "Whip" Buck, one of the Phillies' limited ownership partners, died Sunday.

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."
