Phillies President Andy MacPhail announced today that Michael Stiles has decided to retire from his full-time role at the Phillies as executive vice president and chief operating officer on June 30, 2017. 
Stiles, 71, joined the Phillies in 2001 as vice president for administration and operations, after a legal career as a city prosecutor, trial judge, and the United States Attorney for the Eastern District of Pennsylvania. In February 2015, he was promoted to the position of Phillies executive vice president and chief operating officer, spearheading all business operations and supervising the general administration of the club.
"Mike has played a vital role in his 17 years at the Phillies, leading a talented management team during some of the most successful years in the club's history," said MacPhail. "His contributions will be missed by all who have had the privilege of working with him, but we certainly respect his decision to test retirement after an exceptional career both in the law and at the Phillies. I am very pleased that Mike has agreed to stay connected to our organization, in a consulting capacity, after he leaves his full-time role." 
As a result of Stiles' retirement, David Buck, who currently serves as senior vice president of marketing and advertising sales, will be elevated to executive vice president. Additionally, John Nickolas, who currently serves as vice president and chief financial officer, will be promoted to senior vice president and chief financial officer. Rick Strouse will be promoted from vice president and general counsel to senior vice president and general counsel. The aforementioned promotions will be effective July 1, 2017. MacPhail commented further: "We are very fortunate to be able to draw upon these accomplished executives, and others, as we restructure our organization after Mike's retirement."
