Given all the injuries the Cards are now having to deal with to key players, I favor bringing Adams up to the Big Tent ... now. At the start of the season I was not for this move, but I suspect that this injury problem involving mostly the same players will persist throughout the season ... even tho I hope not.
This season the Cards have had to deal with injury & DL assignments for Schumacher, Linewhatever (irrelevant I think), Craig, Jay, Puma, Beltran, and KMac. That list has too many Key players that are needed for the success of the Cards. And the list doesn't include, yet, Holliday, Furcal, or Freese who have had significant injury problems in the recent past seasons.
I appreciate your posting to keep us up-to-date on the farm boys. It does seem like Tavares, Adams, and Wong are sure-fire roster riders within the next two seasons.
