Smith (knee) completed a 25-pitch bullpen session Friday, Adam McCalvy of MLB.com reports.
The mound session was Smith's first since suffering a torn LCL in his right knee while attempting to take a shoe off in the clubhouse in late March. He decided to forego surgery and take the rest and rehab route, and while Smith seems happy with his progress to this point, he's not out of the woods yet by any means. The lefty will continue to build up strength for now with eye toward ultimately heading out for a rehab assignment.
