Rivas will start at first base and bat ninth in Monday's game against the Pirates.

After going 3-for-6 with a walk and two runs scored in the Cubs' final two games of their weekend series with Atlanta, Rivas will stick in the lineup for the third contest in a row. He looks like he'll serve as the Cubs' primary first baseman while Frank Schwindel (back) is on the 10-day injured list.
