David Dombrowski (born July 27, 1956) is an American baseball executive who serves as the President of Baseball Operations for the Philadelphia Phillies of Major League Baseball (MLB). Dombrowski also previously served as the general manager of the Montreal Expos, the general manager and president of the Florida Marlins and Detroit Tigers, and president of baseball operations for the Boston Red Sox. He has helped build four different franchises (Marlins, Tigers, Red Sox, Phillies) into pennant-winning teams, and he has won the World Series twice — with the Marlins in 1997 and the Red Sox in 2018. Career Chicago White Sox Dombrowski began his career with the Chicago White Sox in 1978, as an administrative assistant in their minor league organization. He moved up the ladder to assistant general manager to Roland Hemond by his late 20s, but was purged during Ken Harrelson's one-year reign in 1986 as the White Sox front-office boss. Montreal Expos Dombrowski joined the Montreal Expos front office as director of player development for the 1987 season under Bill Stoneman, and on July 5, 1988, he became, at age 31, Montreal's general manager—the youngest in MLB at the time. Dombrowski built up the Expos farm system during his term. He drafted, among others, Rondell White and Cliff Floyd. The team enjoyed .500 or better seasons in 1988–90 but struggled on the field in 1991. Concurrently, the National League expanded to 14 teams, with two new franchises to begin play in 1993. One of those teams, the Florida Marlins, recruited Dombrowski to become its first general manager; he was appointed on September 19, 1991. Florida Marlins Dombrowski spent about a decade in Miami, working under owners H. Wayne Huizenga and John W. Henry. In 1996, he hired Jim Leyland to manage the team; they had previously worked together for the White Sox in the early 1980s, with Dombrowski as assistant general manager and Leyland as third base coach. Although Dombrowski built a sound minor league system, the Marlins achieved their first great success—the NL pennant and 1997 World Series title—with a team composed of many high-salaried players signed as free agents. The following year, Dombrowski presided over Huizenga's mandated fire sale of those veteran players, and the Marlins failed to reach a .500 winning percentage in each of Dombrowski's final four years with the franchise. In November 2001, Dombrowski left Florida to become the president of the
