At the All Star break:
Bryce Harper's 2012 MLB stats:
.282/.354/.472 for an OPS of .826, with 8 HRs, and 10 SBs. Bryce has 277 PAs is 63 games.
Todd Frazier' 2012 MLB stats:
.278/.345/.556 for an OPS of .901 with 9 HRs and 1 SB. Todd has 200 PAs in 60 games.
Yet not only is Harper an all star, Frazier was never even mentioned. Heck, Frazier hasn't convinced Dusty that he should be starting at third over Scott Rolen.
