PHOENIX -- D-backs television play-by-play man Daron Sutton was not in the booth for Friday's opener against the Cubs at Chase Field.
The club declined to say why Sutton was not working the game and Sutton did not immediately respond to a voice mail seeking comment.
"We've made a change in the broadcast-talent lineup," team spokesperson Josh Rawitch said. "Daron will be taking some time off."
Rawitch declined to say how long Sutton would be away.
Greg Schulte, the team's radio voice since 1998, filled in on TV for Sutton on Friday. Jeff Munn took the radio play-by-play reins for Schulte.
