The Pirates are in dire need of a starting pitcher, but general manager Neal Huntington doesn't appear close to making a move for outside help.
Pittsburgh lost 20-0 to Milwaukee on Thursday.
Chris Jakubauskas will be recalled by the Pirates on Friday. He was a member of the team's Triple-A rotation in Indianapolis.
Kevin Hart, also in the Triple-A rotation, will be summoned to start Saturday, according to the Pittsburgh Post-Gazette.
"By the time we could sign and stretch out one of the free agent options, we'll have internal solutions," Huntington said.
