Given the weather, you really have to take the results so far with a couple grains of salt - some guys just struggle with the cold (how often has Eflin pitched in those kinds of conditions, for example?).
Altherr keeps impressing, I think he's pretty much a fixture in the OF, and playing LF at times just makes him more valuable, how many OFs are plus plus fielders where ever you put them? He's a highlight film in the field.
And he's consistently getting on base as well as hitting for power. And has good speed on the basepaths.
He just might be better than anyone expected. Maybe the 5 tool star they've been trying to draft for over a decade (Golson, Hewitt et al).
