Perez (ankle) likely won't be activated until rosters expand, Eric Stephen of True Blue L.A. reports. Perez hasn't pitched since Aug. 3 after hitting the DL with bone spurs in his right ankle. Prior to landing on the disabled list, the 29-year-old reliever owned a shaky 5.03 ERA and 1.45 WHIP on the year. The team simply feels comfortable enough to extend his rehab work, and call him up to provide bullpen depth in September.
