I expect the Pat Winkel injury will not change his brother moving to CF and Crawford taking over at 1B. I suspect they see Chris as the best solution for the CF spot given his athletic ability, and that if this move works out it could give him more notice on the part of pro scouts. I think the coaching staff wants to establish Crawford as an everyday player first, and will bring him along slowly on the mound, thus reducing the amount of stuff Crawford needs to figure out during his freshman season. At least that is the impression I have gotten in my head, but we will see how that develops. Of course, if Crawford has a slow start at the bat, that could bring Chris Winkel back to the infield, but it really sounds like the coaching staff really likes the offense that Crawford could potentially supply.
I suspect the D.H. spot will now be a revolving door at the beginning of the season unless someone gets hot and takes over the spot. Another possibility depends on Christian Fedko. If his defense at 2B does not satisfy the coaching staff, then Fedko could end up seeing more time as the D.H., especially now that Paul Gozzo will be getting the bulk of his playing time at catcher.
