A lot is being made about Carlos Guillen’s move to first base and what should be a decrease in stress on his knees because of the move. Seems like this might be a myth because Will Carroll still gives Guillen a red light in a column on surprising red and green lights and he talks about how most of the stress on the knees comes from standing, not running. He’ll be doing just as much standing first and he’ll have to get used to a newer position, hence the chance that he lands on the disabled list isn’t really diminished. Still, the move makes sense with Edgar Renteria being the at least moderately slightly superior fielder at shortstop.
