MILWAUKEE -- The Chicago Cubs are set to make a pair of roster moves Tuesday in an effort to bolster the pitching staff.

Left-hander Alex Hinshaw, who was claimed off waivers from the Padres on Sunday, is expected to be activated, as is lefty Chris Rusin, who will start the night game against the Milwaukee Brewers.

The likely candidates to be sent down in order to make roster space are left-handed reliever Jeff Beliveau and left-handed hitting infielder Adrian Cardenas.

Beliveau had been effective in his short stay in the major leagues until Monday when he gave up two home runs while only facing three Brewers hitters. Before Monday’s outing, Beliveau had been on a run of seven consecutive scoreless outings.

Hinshaw, who was in the big leagues this season for the first time since 2009, was 1-1 with a 4.50 ERA over 31 outings with the Padres. Rusin will be making his major-league debut on Tuesday.
