The Rockies demoted Iannetta to Triple-A Colorado Springs after Monday night. Iannetta had a .133 average and 11 strikeouts in 30 at-bats.
With Miguel Olivo hitting .311 going into Tuesday night's game with the D-backs and having earned regular playing time, Tracy said the best action for Iannetta would be to play regularly in Colorado Springs. Veteran Paul Phillips was called up from Colorado Springs to serve as Olivo's backup.
"Chris Iannetta at times looks very confused as an offensive player," Tracy said. "I see uncertainty in his body language. I see uncertainty in his decision-making process at a time when the pitcher's getting ready to throw a baseball to him and he has to make a decision."
Tracy also detailed some technical issues.
"I see a guy who's working below the ball," Tracy said. "Instead of working down through the ball, he's spending quite a bit of time below the ball and up through it.
"If all that's going on, I don't think you're going to have an opportunity to really solve all of that by hitting off of one of our staff members five out of seven days a week and getting two chances a week to play. I don't think we're going to get it fixed. We needed to be proactive and get him in an arena to give him a chance to fix what's ailing him."
