It seems like a common theme for several of the young players in Spring Training with the Cardinals:
“This is a make or break year for the young (insert position here).”
Or, for some other players:
“(Insert player name) will look to improve their stock heading into free agency after this season.”
Michael Wacha could be considered to be both of these players. He’s also a player in the “If he can stay healthy/effective, he’ll be an important asset” club. Wacha has had some lingering injury issues that have forced him to miss some time the last few seasons.
