Brash (lat) threw a bullpen session Saturday and is scheduled to throw another one in Boston early next week, Ryan Divish of The Seattle Times reports.

Brash threw 15-to-20 pitches in his latest mound session as he continues his recovery from a right lat strain. The hard-throwing setup man has missed extended time with no indication that he has faced live hitters. Given that, a return Tuesday when rosters expand seems unlikely.
