Gomez was in right field on Tuesday because the Brewers' athletic trainers wanted Corey Hart to take one more day to rest his sore right hamstring. The center fielder was rookie Lorenzo Cain, who has made the most of an opportunity that opened when Gomez was hit in the head by a pitch on Aug. 3 in Chicago.
Entering play Tuesday, Cain had a .333 batting average and a .377 on-base percentage in 48 at-bats. Gomez had a .228 batting average and a .286 on-base percentage in 246 at-bats.
Macha said playing time would go to whomever is playing best. He'll have to juggle Cain, Gomez and recently-acquired Chris Dickerson in center field between left fielder Ryan Braun and right fielder Hart.
"Right now, Cain is in that spot," Macha said. "The way I do things, I'm not going to bury anybody. Cain will probably get a day off and somebody else will be in there playing. They'll get an opportunity to go out there and prove their worth. That's the way I operate."
Gomez told MLB.com over the weekend that, "I'm not a backup. I'm 24 years old. I'm the center fielder, and I have to take my job again."
He stood by that stance on Tuesday, telling the Milwaukee Journal-Sentinel, "I'm the best center fielder on the team."
The Brewers didn't need to make a corresponding roster move for Cain on Tuesday because they had already released reliever David Riske on Monday's day off. By the time Riske was let go, Gomez had already passed the series of Major League Baseball-mandated tests required of players who suffer concussions.
