Ankiel’s place on Cards’ roster a mystery

The St. Louis Cardinals are reporting that Rick Ankiel is injured:

In making the transition from pitching to playing the outfield, talent has scarcely been an issue for Rick Ankiel. A balky body, however, keeps protesting. On Monday, Ankiel sustained his third injury in the 12 months since he made the switch, suffering a strained left patellar tendon in an intrasquad game. He underwent an MRI at Jupiter Medical Center on Tuesday, and he will be held out for at least 10-14 days. The injury was characterized as a Grade 2 strain, the middle of three levels.

Here’s my question: why the heck is Ankiel still on the Cardinals’ roster? This kid imploded in the post-season six years ago and has never recovered. Yet they don’t send him to the minor leagues, but keep him on the 40-man roster and try to convert him to an outfielder.

Why? Is his dad on the board of directors or something? I’ve never heard of a team keeping a dead weight like this for more than half a decade. It’s time to cut the kid loose so he can pursue other interests while he’s still young.
