Whenever you have a question on the rules, its always best to 1st take a look at them. But before you do anything, make sure the rule you’re looking at is the right one! The NCAA rule book is a free download here: : http://www.ncaapublications.com/p-4183-2011-2012-baseball-rules-2-year-publication.aspx
Actually, the way it looks, you’ve stumbled into a rule change for this season. Nice job! As you can see, the wording has been changed about the pitcher’s glove. Now how that rule is chosen to be interpreted is a matter for the umpires and the rule’s committee, but as Zita said, why look for trouble? Is it that important to make a fashion statement?
Also, remember that the rules MLB uses are not not the rules used by the NCAA or the NFHS! When you get to nit picky stuff like this, save yourself a lot of time and trouble and only use the correct rule book as a reference.
