In 1999,
Baseball America named Hill as one of 10 people in baseball whose prominence will increase significantly in the first decade of the new century. It quoted strong sources who said he would turn into a successful
general manager before the 2010 season. That year, he began working for the
Colorado Rockies, serving as their director of player development until leaving to join the front office of the Florida Marlins (later renamed the
Miami Marlins). Hill was a part of the Marlins organization for over a decade, having joined their front office in 2002. At the age of 32, Hill was named to the "Hot List" by the
Black Enterprise magazine in their December 2003 issue, a list that represents the best and brightest African American executives under the age of 40. Over time, Hill has served positions such as vice president, assistant general manager, and general manager. Hill worked closely with then-
president of baseball operations Larry Beinfest, focusing on roster management, payroll and contract research and negotiation, and waiver and rule compliance. Hill signed an extension through the 2015 season on September 29, 2007, and was promoted to president of baseball operations of the Miami Marlins in September 2013. In 2021, Hill was named a co-Senior Vice President of On-Field Operations for MLB. ==Personal life==
