Tigers activated C Alex Avila from the 15-day disabled list. Avila has been sidelined since August 10 with a concussion, but he didn't report any issues after catching seven innings on back-to-back nights during his rehab stint. The 26-year-old is batting just .198/.288/.340 over 73 games this season, though he was showing signs of a turnaround prior to going on the disabled list.
