The Brewers placed second baseman Scooter Gennett on the 15-day disabled list with right oblique tightness on Thursday and selected infielder Hernan Perez from Triple-A Colorado Springs.
Gennett felt oblique tightness in the batting cages before Tuesday's game and was scratched about 30 minutes before first pitch.
Perez has thrived in Triple-A to begin the season, hitting .339 with one home run, four doubles and 11 RBIs in 16 games.
