Dave Barnett takes indefinite leave

ARLINGTON, Texas – Texas Rangers television broadcaster Dave Barnett has chosen to take an indefinite leave of absence that he expects will last the remainder of the season.

Steve Busby will continue to handle the play-by-play duties on television and Matt Hicks, recently hired from Double-A Corpus Christi by the Rangers, will stay on with Eric Nadel on the Texas Rangers ESPN Radio Network.

Barnett, 54, issued a statement through the club.

“I want to thank everyone for your kind sentiments and words of encouragement over the last couple of weeks,” Barnett said. “It has meant a lot to me during what has been a very difficult time. Effective immediately, for health reasons I will be taking an indefinite leave of absence from my broadcasting duties that I expect to last for the remainder of the season.”

Barnett has not broadcasted a Rangers game since June 18, when he had a strange on-air issue in the eighth inning of that game in San Diego.

"A 2-1 game, the tying run at second on a leadoff single by Chase Headley," Barnett said on the telecast. "The go-ahead run ... is at fifth, on what Adams is insisting on calling a botched robbery. What actually happened was his henchman took a piece literally out of ..."

Barnett finished the game without any further issues, but went in for a battery of tests to determine what caused the incident. He said shortly after that game that he thought it might be migraine headaches. The club has not said what caused Barnett's on-air issue.
