Grant Balfour (knee) threw 40 pitches off a bullpen mound on Wednesday morning in Athletics camp.
That's up from his 35-pitch workout on Monday. Balfour has now thrown three full-intensity bullpen sessions and should be able to fit in several Cactus League relief appearances before the start of the regular season. He will open the 2013 campaign as Oakland's closer.
