What's Up With Colby?

The Cards top prospect, Colby Rasmus, is struggling. That is putting it very gently. His line is really starting to worry me. In 198 at bats, he is 21 point below the Mendoza Line. His OPS is about 200 down from his career mark. The homers are there---somewhat. He has 6 to go along with 6 RBIs. Early on, I thought it was a fluke--maybe tough luck. Nope. Line drive rate is down from 23% to 8%. That is scary bad. Strikeouts and walks basically line up to his career numbers, but he is just not squaring the ball. Now, he is routinely going 0 for games and hitting 8th in the lineup. Hopefully, he will figure it out soon and cool the worries in the minor league blogosphere, but right now there is cause for concern.
