Rivera was recalled from Triple-A Colorado Springs Friday.
With Aaron Hill being traded, the Brewers opted to recall Rivera to fill the vacant infield spot. Rivera spent some time with the Brewers earlier in the season, but struggled to produce at the plate, going 10-for-49 with 19 strikeouts and just one walk. His batting was better at Colorado Springs, although not by much, as he posted a .232/.282/.305 line.
