Cardinals activated RHP Fernando Salas from the 15-day disabled list; optioned him to Triple-A Memphis. Salas is recovered from his right shoulder injury, but the Cardinals want him to get in more work against Triple-A competition. The 28-year-old right-hander has a 3.86 ERA, 1.10 WHIP and 12/3 K/BB ratio in 16 1/3 innings of relief this season out of the St. Louis bullpen.
