ARLINGTON -- Texas Rangers owner Thomas O. Hicks announced on Tuesday that John Hart has resigned as executive vice president/general manager to become senior advisor/baseball operations and that assistant general manager Jon Daniels has been promoted to general manager.
Hart, 57, was the Rangers' GM for four years. He had been the GM of the Cleveland Indians the previous 10 years. After the Rangers finished 89-73 in 2004, Hart signed a two-year contract extension designed to keep him with the organization through the 2006 season.
"John has brought a new level of professionalism to the Texas Rangers over the last 4 years," Hicks said. "During his tenure, the organization has improved on the field at the Major League level while enhancing the Minor League system with a number of top prospects.
At one point in his Texas tenure, it was anticipated that Hart would move into a consultant's role with Grady Fuson becoming general manager. But Fuson left the organization last year after it was determined that Hart would again be the GM in 2005.
"The management team he put in place allows me to promote Jon Daniels to become the youngest general manager in Major League history," Hicks added. "I am confident in his abilities for the continued growth of the organization."
Hart just completed his fourth season as general manager of the club after being appointed on Nov. 1, 2001. He built the Rangers with a core of younger players, signing players such as Michael Young, Hank Blalock and Francisco Cordero to multiyear contracts. He also helped build the club's minor league system by acquiring 11 top prospects in trades during the course of the 2003 season.
Daniels, who becomes the youngest general manager in Major League Baseball history at 28 years, 41 days, becomes the eighth general manager in club history. He joined the Texas organization in 2002 as a baseball operations assistant before being promoted to director of baseball operations in October of 2003 and then again to assistant general manager in July of 2004.
A 1999 graduate of Cornell University in upstate New York, he earned his degree in applied economics and management. He is a native of New York City.
