It's highly doubtful that any logo used at a level like MLB is going to be using off-the-shelf typefaces. It's likely a hand-drawn custom face.

If you are looking for something pretty close try team spirit and sports jersey both free fonts found on-line

with some modification (esp. on the 'C') you might also try Fenway Park:

Thanks for all your posts...unfortunately, it is the "C" that I wish to obtain...
