A former outfielder for the Cubs and the Yankees who once played for Johnny Oates in the Minor Leagues, Dayett has spent 10 seasons in the Rangers farm system as a hitting and special assignment coach.
He has worked with many of the Rangers young players currently on the team. He has Parkinson's Disease and the promotion allows him to be covered by Major League health insurance through Opening Day. That is a significant benefit.
"He is a guy as an organization we feel strongly about," Rangers general manager Jon Daniels said. "It's a small gesture of our appreciation. It's about showing respect for what he has meant to the organization, especially with the young guys that he has worked with."
In other front office news, assistant general manager Thad Levine has withdrawn from consideration for the D-backs GM opening. He will remain with the Rangers and will add director of international scouting to his list of duties.
