Perez (ankle) was activated from the 15-day disabled list Monday, Eric Stephen of True Blue LA reports. Perez remained on his rehab assignment at High-A Rancho Cucamonga probably longer than was necessary, but in waiting until Sept. 1 to bring him back, the Dodgers didn't have to make a corresponding move. He's been mostly abysmal this season with a 5.03 ERA, 1.44 WHIP and just 30 strikeouts in 39.1 innings, putting him at risk of being left off the team's postseason roster.
