The Brewers added four minor-leaguers to their 40-man roster Wednesday, protecting them from being plucked away by another team in the Rule 5 draft in December.

The four players added are first baseman Hunter Morris, infielder/outfielder Jason Rogers, right-hander Brooks Hall and right-handed reliever Kevin Shackelford. Wednesday was the deadline for teams to protect players on their 40-man rosters.

Morris, Rogers and Shackelford were expected additions to the roster while Hall was a bit of a surprise. The moves left the Brewers with a full 40-man roster.

Morris, 25, considered one of the top 10 prospects in the organization, was the Brewers’ 2012 minor-league player of the year at Class AA Huntsville but struggled for much of last season at Class AAA Nashville. In 134 games, the 2010 fourth-round draft pick batted .247 with 24 home runs and 73 runs batted in, with 122 strikeouts and a .310 on-base percentage.

Rogers, 25, a 32nd round draft pick in 2010, made a big leap forward this year at Huntsville. He batted .270 with 22 home runs and 87 RBI in 133 games, earning the organization’s minor-league player of the year award. Rogers went to the Arizona Fall League to play the outfield and increase his versatility, and batted .211 with two homers and eight RBI in 18 games.
