Mark Grace and Daron Sutton will not return as television announces for the Arizona Diamondbacks next season.
The club confirmed that it is seeking replacements for the pair.
Grace, the popular former major leaguer and the team's color analyst, left the crew voluntarily in August after his second driving-while intoxicated arrest in 15 months. Sutton, the play-by-play announcer, was suspended on June 30 for unspecified ''philosophical differences.''
Greg Schulte, who had taken over the television play-by-play duties, will return to his role as radio announcer.
