With the Major League Rules allowing all clubs to expand their active rosters to 40 today, the Cardinals announced a flurry of moves, including a couple of surprises.
Activated OF Jose Martinez from the 10-day IL.
Purchased the contracts of RHP Mike Mayers and C Joe Hudson from AAA Memphis. To make room for Hudson on the 40-man roster, transferred OF Lane Thomas from the 10-day IL to the 60-day IL.
