Bednar (oblique) threw a bullpen session Friday and is progressing well, Jason Mackey of the Pittsburgh Post-Gazette reports.
There are nine games left in the regular season, and manager Derek Shelton said the team should have some clarity on when Bednar will be available within the next few days, so it's not a guarantee he will make it back before the end of the season, despite the fact he is trending in the right direction. Chris Stratton has been working as the closer, but no Pirate has recorded a save within the past week.
