I have some issues with this:
1) His rookie year was 2008, not 2007 like the inscription says, so perhaps this could be from his time in the minors in 2007
2) I didn't think he wore #3 in the minors, like the decal on the knob
3) There appears to be writing under the decal, so maybe it was a minor league bat that was also used in the early part of the 2008 season
4) I checked out getty images and there are only pics from the 2007 futures game, and not many (however you can see he is using a marucci bat in the futures game)

It shows a ton of game use so its possible it was held on to for a while but i'm just not too sure. (I'm approx. 65% confident at this point)

I have no issues with the autograph as I have other signed GU Longoria items and also double checked the psa/dna and it's authentic

I'm not concerned with price at this point, just authenticity.

Your input is appreciated. Thank you.
