Paredes misplayed three grounders in the outfield on Friday and Saturday, a problem interim manager Tony DeFrancesco said was about equipment.
"We're finding out that his glove was not the proper glove," he said. "It really had a loose top to it, and every time he put the glove on the ground the top would break down, so there was really no pocket for the ball to go in."
Astros third-base coach Dave Clark, who works with the outfielders, made Paredes ditch the glove for Sunday's game.
"We don't want to see any of those plays," DeFrancesco said. "You see one of those every five months, inconsistency on ground balls, but to see three in two days is not what we're looking for. We're going to make some adjustments to that."
