It will come down to Belt(1b)vs Schierholtz(RF)for a starting job.

If Belt is crushing the ball in ST, IMO he'll be the opening day starter @ 1b, with Huff in LF and Cabrera in RF

CF-Pagan .280-avg 35-sb
2B-Sanchez.280-avg
3B-Sandoval.300-avg 25-hr
C-Posey .295 18-hr
RF-Cabrera .290-avg 15-hr/15-sb
LF-Huff .280-avg 20-hr (assuming he's in shape)
1B-Belt .255-avg 23-hr
SS-Crawford .220 5-hr
Pitcher

I watered down the stats, and it's still not a bad lineup
