Strop (knee) threw a bullpen session Thursday, Mark Gonzales of the Chicago Tribune reports.
A groin strain delayed Strop's recovery from left knee surgery, but he cleared a major hurdle Thursday with his first bullpen session. He said it went "fine" and he may get back onto elevated ground for more work this weekend. The Cubs are probably just focused on getting Strop back for the postseason, but it appears he has a chance to return for the final week or so of the regular season.
