Nova (elbow) has been officially activated from the 60-day disabled list, Bryan Hoch of MLB.com reports. Nova was already announced as the pitcher for Wednesday's game, so it was just a matter of time before the move was made. He will replace Brendan Ryan (who was placed on the 15-day DL) on the 25-man roster, and shouldn't be limited much (95-100 pitches) in his season debut.
