Rawlings bat help. Newbie question

[Tunis]

Hello,
I have used the search function and learned a couple of things but I still have a question. I recently purchased a Jose Lopez Rawlings bat. It is blond in color with a blue stripe.
The knob has the following:

Lopez-written in pen
M433B
454 05

The barrel says "Big Stick"
"Jose Lopez" in block letters
Professional Model

Is this a minor league bat? He was called up in 2005 and I have found a picture(Getty) of him holding a similar bat in July of 2005.

Maybe he carried up to the "Big Leagues"?

If it is a Major League bat, should it say something different than "Professional Model"? Maybe "Pro" or "Mariners"

Thank you in advance.
Paul

You're correct, Paul. It's a minor league bat made in 2005. MLB bats made in 2003 and later have -PRO- under the player's name. If he was called up in 2005, it well could be a minor league bat he brought up with him.

Thanks for your help, Jeff.
