He will be a starter... at least that's the plan for now.
The Post-Dispatch broke this story earlier this evening.
Good move. Very low risk, possibly high reward. If we're to believe the mainstream media, Adam Wainwright and Mark DeRosa were all but giving the GM a handy to get this guy in house, so I think the players are going to be receptive.
Plus, if nothing else, he's been in a shitload of playoffs, so that's got to help some of the younger players as the Cardinals look to be headed for the postseason for the first time since 2006.
