Athletics' Paul Blackburn: Making progress in throwing program

Blackburn (foot) threw a bullpen session Tuesday at Angel Stadium and is set to complete another one Saturday, MLB.com reports.

The right-hander has been making steady progress over the last week-plus, as he's already thrown two bullpen sessions and has seemingly come away from that activity without setbacks. If Saturday's session also goes off without a hitch, Blackburn could progress to facing hitters as the next step in his recovery.
