Sporting News'1962 Official Baseball Guide and Record Book, published in the Colt .45s' maiden season, lists Giles as the club's traveling secretary and publicity director.[6] Subsequently, he became promotions director, and focused on that role after the renamed team moved into the Astrodome in 1965.
Philadelphia Phillies
Giles started with the Phillies as the vice president of business operations in 1969. He worked his way up in the organization, with stops as executive vice president and president, before becoming the chairman in 1997.[7] He was succeeded as chairman by David Montgomery and became chairman emeritus in 2015.[8]
Giles was also part of the ownership group that bought the Phillies from the Carpenter family in 1981, heirs of the Du Pont family fortune.[9][2] The group was composed of Giles, Claire S. Betz, Tri-Play Associates (Alexander K. Buck, J. Mahlon Buck Jr. and William C. Buck), and Double Play Inc. (John S. Middleton).[10] Mahlon Buck died in 2011.[11] Claire S. Betz died in 2014.[12] The group reportedly purchased the team for $30 million.[13] In 2023, the team was valued at 2.8 billion dollars.[14][15]
Around 2012 or 2013, Giles sold his last shares of the Phillies.[1] He owned at one point about 20% of the team.[1]
