Diekman (abdomen) was activated from the 60-day disabled list Friday, Jeff Wilson of the Fort Worth Star-Telegram reports.
As expected, Diekman was reinstated with active MLB rosters expanding to 40 players Friday. The lefty showed no real ill effects while on his rehab assignment from the three separate surgeries he underwent earlier this year to repair and rebuild his colon, posting an 8:0 K:BB in 6.1 scoreless innings between Frisco and Round Rock. He should immediately step into a back-end role in the Texas bullpen.
