I'm not an expert on MLB jerseys, but the stitching looks crisp and the patches look well defined. In my limited opinion I'd say it's probably genuine, but I think we need someone with more experience with these majestic jerseys. Hopefully someone will confirm it for you.

i would say that is legitimate. any time you have a jock tag that is screen printed on like that instead of sewn on, you are pretty much in good shape. everything else looks legit too. plus it has the 6300 on the tag.
