O'Malley (shoulder) was cleared to play catch for the first time since undergoing surgery in early May, Ryan Divish of the Seattle Times reports.
O'Malley still has at least a month to go before returning but progress is a positive start. The 29-year-old underwent arthroscopic surgery after dealing with a shoulder problem that was causing him issues while he was on the disabled list for an appendectomy. O'Malley hit .229/.299/.319 last season in 89 games of work.
