Brewers call up George Kottaras
Nieves was 7 for 50 without a homer or RBI in 20 games. Kottaras started the season with the Brewers and appeared in nine games, going 7 for 26 with four RBIs before getting sent to Triple-A in late April.
The Brewers announced the moves before Wednesday's game against the Chicago Cubs.
