"On a day-to-day basis, there won't be any dramatic difference in the role," Daniels said on a conference call. "I think, more than anything, it's a recognition of the work of not just myself or Rick, but our corps under strong leadership and what the organization has accomplished over the last eight years."
Daniels is in his eighth season as general manager and his 12th with the organization. In the past four years, the Rangers won a pair of American League pennants, three playoff berths and had four winning seasons.
George, who oversees team business, has been the Rangers' COO since 2010. During his tenure, the Rangers set franchise records for attendance in each of the past two seasons.
Team president Nolan Ryan praised the work of the Rangers' front office in a statement the club released Friday afternoon.
"I am proud of what we have accomplished as an organization over the last several years," Ryan said. "That has been due in large part to the efforts of a lot of talented and dedicated individuals who work in all areas of the ballclub. I want to congratulate Jon and Rick on their promotions as the organization moves forward with a tremendous group of employees to achieve an even greater level of excellence in 2013 and in the years to come."
Daniels deflected all that credit right back onto Ryan.
"He's the heart of the franchise in the way that he's created a culture," Daniels said. "With the size of the company, it's a family-type atmosphere and people want to be here."
