Gomez, who is hitting .350, had one of the Brewers' two hits against lefty Mike Minor on Saturday in his fourth start of the season, and had a pinch-hit double on Friday.
Morgan, meanwhile, went 0-for-3 in the series opener against the Braves to drop his average to .167. He batted .304 last season.
"We need to get him going," Brewers manager Ron Roenicke said. "He's obviously very important to our lineup."
Gomez, bouncing back from a .225 season a year ago, also needs playing time.
"I'm trying to get Gomey in there a little more," Roenicke said. "I've got to figure that out."
But the Brewers need what Morgan can potentially bring them in the second spot in the lineup, especially with leadoff hitter Rickie Weeks starting slowly.
"He was seeing the ball so well in Spring Training," Roenicke said of Weeks. "I really thought he was going to get off to a good start."
