Lyons (knee) was activated from the 10-day disabled list Thursday.

Lyons will take the roster spot of Jhonny Peralta, who was sent to the 10-day disabled list with an upper respiratory illness. He looked sharp in his three rehab appearances with Triple-A Memphis, allowing just two runs while striking out 14 batters through 14 innings. He'll rejoin the Cardinals and provide some length out of the bullpen.
