I).Gagliano, 39, has been in various capacities with Magna Entertainment, which owns the Maryland Jockey Club, since 2002. The Maryland Jockey Club encompasses Pimlico and Laurel."It was becoming increasingly difficult for me to maintain a high level of work performance while still residing in New Jersey. This was a difficult decision, but one I needed to make for personal reasons," Gagliano said in the release."We are disappointed to lose Jim from our management team, but understand his desire to spend more time with his young family in New Jersey," stated Maryland Jockey Club president and CEO Joe De Francis. "His contributions over the past year here in Maryland have been enormous and we wish Jim all the best in his future career." Gagliano added, "My time in Maryland has been very fulfilling. While there is plenty more to accomplish, I believe we achieved a great deal, culminating in a record smashing Preakness."Gagliano was executive vice president and general manager at Philadelphia Park when he joined Magna to oversee the company's off-track betting operations.He moved to Philadelphia Park, which is part of Greenwood Racing, after having served as associate general manager at Meadowlands in New Jersey.
