Small sample size + right conditions (weaker opponents and hitters park) will do that:
They clearly played very well vs reds (2-157 team with relievers beyond tired) and Spring Hill Sluger II (65-94 Coors team).
I've only check 4, and quickly (so there might be a little mistake or two):
-Metivier 47/119 total, 15/28 vs reds, 10/14 vs Coors team. 22/77 otherwise looks ok to me on a Baker Bowl team (8 contact, 5 power).
-Matanguihan 46/104, 17/34 vs reds, 7/11 vs Coors. 22/59 thats very good but not .442 (10 contact 3 power).
-Ware 39/79, 19/33, 9/15. 11/43 (7 contact 1 power)...
-Monroe 33/89, 16/33, 6/14. 11/41 (8 contact 1 power)...
Monroe hit 22/47 .480ish and the 3 others were 25/42, 24/45 and 28/48 clearly above .500 vs 2 weak pitching teams for somewhere between 35% and 55% of their ABs.
You use them in the right conditions, which is not a bad thing, but it looks quite normal to me.
Maybe I missed something, but its the first thing that jumped to me when looking game log.
