The Brewers moved six players off the big league camp roster, including one potential fifth starter candidate, in the first round of cuts Sunday.
That fifth starter candidate is right-hander Amaury Rivas, who was optioned to Triple-A Nashville. He was one of the players mentioned as a potential fill-in for Zack Greinke, who will miss the start of the season with a cracked rib.
The Brewers also optioned pitchers Dan Merklinger and Cody Scarpetta to Double-A Huntsville and returned pitchers Robert Hinton and Roque Mercedes and catcher Anderson De La Rosa to Minor League camp.
The first Minor League full-squad workout was Sunday, but all six players were given until Tuesday to report.
With the moves, 47 players remained in big league camp.
