Here is an excerpt from a David Ortiz Rawlings maple on ebay:

Title:

2006 David Ortiz Game Used Rawlings Bat Boston Red Sox

From his franchise record HR year!54 Home Runs in 2006!


Here is the questionable part:
The knob of the bat features Ortiz's # 34 in the proper handwriting as found on all of Papi's bats. The knob features the factory marks including the number M456B and 75405. Don't miss your chance to own a peice of Boston Red Sox history

My questions are doesn't an 05 at the end of the manufacturer stamp on a Rawlings bat mean this is a 05 bat?Also do many players use bats from previous seasons?I figured this must be debated cause right now there is a huge difference in price of an 05 next to an 06.Thanks
