Arizona Diamondbacks' TV color analyst Mark Grace is taking "an indefinite leave of absence" from the broadcast booth.

In a news release, the team announced that Grace – who also played for the D-backs before his retirement as a player – was taking time off "to seek personal assistance."  The release also said, "Due to the nature of Grace's request, the team will have no further comment on the matter at this time."

However, Scottsdale police report that Grace was arrested Thursday night for DUI.  It was his second DUI arrest since May of last year.  Police indicate Grace was stopped for an expired license plate and was given a field sobriety test, which he failed.

Police also say Grace, 48, was driving without an ignition interlock device, required after his 2011 DUI arrest.  In addition, he was driving on a suspended driver's license.

Former Diamondback Luis Gonzalez, currently a member of the team's front-office management, will be the color analyst for Friday's and Saturday's games.  As he usually does, Joe Garagiola will fill that role on Sunday's broadcast.

Grace's departure comes two months after play-by-play announcer Daron Sutton left the D-backs' broadcast booth abruptly.  At the time, the Arizona Republic reported that Sutton had been suspended, but Sutton himself later told the newspaper he was taking a voluntary leave of absence because he had "a personal situation I have to deal with."  Sutton is still on leave.
