Chavis (elbow) is expected to be activated for Tuesday's game against the Cubs, Alex Stumpf of DKPittsburghSports.com reports.
The Pirates will finish up a road trip Monday, and Chavis will be ready to rejoin the team when it returns home for a three-game series against Chicago that begins Tuesday. He had been playing regularly for six games in late August before suffering the injury. Chavis hit .364 with one home run and four strikeouts in 22 at-bats over that stretch. Kevin Newman has been seeing most of the starts at the keystone recently, and it's unclear how the playing time will be split over the final six games of the season once Chavis is activated.
