After the Brewers were swept by the Twins in a four-game series last week, Garza and Ryan Braun directed a players-only meeting in an effort to increase communication between players.
Garza told the team, "We have 162 [games]. We're not done yet, so let's just keep going. Let's have fun. Let's get back to playing the way we played."
He'll have a chance to act on his words after struggling in his last start on Tuesday against Minnesota, when he allowed a season-high eight earned runs, which included four homers, over 3 1/3 innings.
The Brewers' offense will look to build off an impressive comeback effort against the Reds on Friday, when they scored seven runs in the sixth inning. Milwaukee also got home runs from Travis Shaw, Braun and Eric Thames on Saturday in an extra-innings win.
"We just needed to score some runs," Brewers manager Craig Counsell said after Friday's win. "In baseball, the energy that you want is created by scoring runs. I love great starting pitching, but there's not a line of high fives after the first inning when there's a zero on the board."
Romano has thrown six innings in each of his last two starts, but he allowed a combined nine runs in those outings.
