I read in the Rule Book that the pitcher can't wear a two tone glove. But I noticed pitchers in the World Series wearing them. What does this rule actually mean?

What World Series ... MLB, NCAA, Legion?

OK,
 

As with many things in MLB this rule is only enforced IF there is a complaint by one of the two teams. It is much like when F3 has a foot in foul ground at the start of the play. If there is a complaint the umpires enforce the rule, to the letter, for both teams.

In the Braves game a few nights ago there was a complaint lodged about the pitcher's glove being two-toned (actually the glove had WHITE piping on it) and the PU made the pitcher change.

Showmanship by the visting team . . . sure but that is MLB.

Ask the M's Arthur Rhoades what he thinks of Omar Visquel.

If you meant the Little League WS, the LL rules allow multi-color gloves if they aren't distracting and they aren't white or gray.

as stated in the July '02 - Volume 8.4 issue of LL's Fairball newsletter:
One of the rules changes for the 2003 season is the amendment of rule 1.15-(a); which, will allow multi-colored gloves.
So, do not be surprised if you see such combinations as: black/brown, red/blue, green/gold, etc.....

Visquel????? That miserable litte $#&%head. Distracting? I'll show him distracting. One of these days I'm gonna take an earring and put it right through his tiny little poor excuse of a manly protrusion. EFF him!

Sincerely,
