Two Tone Maple Bats-2009

[gamer35]

I was wondering why so many players went to two tone maple bats with natural handles during 2009, but it seems as though it is now mandated by MLB:
*All bats must conform to slope of grain wood requirements. Slope of grain is a term that quantifies how straight the grain is on the wood.
*All manufacturers must place an ink dot on the tangential face of the sugar maple and yellow birch bats before finishing. This enables the slope of grain to be viewed easily.
*The orientation of the hitting surface on sugar maple and maple bats should be rotated 90 degrees. To facilitate the change, all manufacturers must rotate the logo they placed on bats by 90 degrees.
*The handles of sugar maple and yellow birch bats must be natural or clear to allow for the inspection of the slope of grain in the handle.
*Manufacturers must track each bat they supply.
*Officials from each manufacturer must participate in an M.L.B.-sponsored workshop on engineering properties and grading practices of wood.
*M.L.B. will visit manufacturers regularly to audit each company’s manufacturing processes.
*Random audits of bats will be conducted by M.L.B. at ballparks.
*A third-party bat certification and quality control program should be established to certify new suppliers, approve new species of wood, provide training and education to manufacturers and address non-compliance issues.

This should be useful in identifying maple game bats from BP bats as only maple bats with natural handles can be used in game action.

not 100% sure of this, I swear Giambi is using all black M9's occasionally right now.

Brian any chance Jason has given you any insight as to why he chooses to flip back and forth between the maple and the ash?

Can anybody provide better definitions than MLB did of things like 'slope of grain' or 'tangential face' (I didn't know a bat had a face). Also, does this mean that yellow birch is now allowed in MLB games?-->

"*The handles of sugar maple and yellow birch bats must be natural or clear to allow for the inspection of the slope of grain in the handle."

BTW, it doesn't say that rock maple bats have to have a clear handle--only sugar maple (and yellow birch).

The 90 degree rotation rule seems interesting, although probably useless...does this now mean that players are hitting what used to be equivalent to the front/back barrel, instead of the left/right barrel? Couldn't players just rotate the bat back 90 degrees in their hand?

Here's a pic from 4/12/2009 of Giambi using an all-black M9:

Looks like it still says New York Yankees under his signature....

I noticed Ryan Ludwick had one AB with an all black Rawlings with the old logo -- so it likely was a maple bat from last season. Other than that, the maple bats used by the Cardinals have conformed to the new rules. As long as players have bats left over from last season, you could see a contraband black maple slip in here and there.

I also noticed David Freese using a B45 yellow birch bat, so they must be legal. B45 is a licensed/approved bat maker.

Well the OP only mentioned sugar maple and yellow birch as requiring a natural handle. Unless there's an omission or if rock maple counts as 'sugar maple,' then rock maple bats don't have to have a natural handle.

Jeff - saw the birch Freese bat...pretty cool.

As for "Rock" maple...IS there a difference? Isn't all Maple - 'sugar maple'...and ROCK HARD MAPLE is the description from LS?

Interesting stuff.

Isn't it possible to see grain with only a light coat of dark stain?

Maybe so. I don't know much at all about wood 'species.' I just thought it was weird that one of the OP's lines said "sugar maple AND maple" bats, which made me think there must be something about 'sugar maple' that MLB isn't liking.
