Dunn (shoulder) will resume throwing off a mound in approximately five days, Ryan Divish of The Seattle Times reports.
Dunn has been sidelined since mid-June with a right shoulder strain. He began a throwing program in early July and is now close to tossing a bullpen session. If all goes well in his initial sessions throwing off the mound, the next step for the right-hander figures to be a minor-league rehab assignment.
